Thermoplastic resin dedicated tapping screw "Nonsert(R)"

Thermoplastic resin dedicated tapping screw "Nonsert(R)"

It is difficult to apply load to the counterpart resin material! It can be reused repeatedly for the same hole.

"Nonsert(R)" is a tapping screw specifically designed for thermoplastic resin that does not require a metal insert. The metal insert, which was necessary for reinforcing the internal thread, is no longer needed, reducing the number of processes. It can also avoid boss breakage in the mating material. The shaft is triangular in shape and has a sharp screw thread angle of 30° (normally 60°), allowing it to be screwed into the resin material with low torque. As a result, it is less likely to impose a load on the mating resin material, enabling repeated use in the same hole. 【Features】 ■ No metal insert required, allowing for repeated use ■ Shape that prevents boss breakage in the base material ■ High pull-out strength ■ Specifically for thermoplastic resin ■ Available in stainless steel and iron (various coatings) *For more details, please refer to the related links or feel free to contact us.

[Case Study] Successful Miniaturization and Weight Reduction of Enclosures with Ultra-Low Profile Screws

[Case Study] Successful Miniaturization and Weight Reduction of Enclosures with Ultra-Low Profile Screws

We introduce a case where the ultra-low head screw "310 Slim" successfully contributed to the miniaturization and weight reduction of vehicle-mounted chargers.

We would like to introduce a case where we proposed replacing the truss screws with the ultra-low head screw '310 Slim' in the automotive industry. With truss screws, the protruding head of the screw posed a challenge as it would get caught and not fit properly. After the proposal, assembly could be done without interference with other components, and when placing the housing inside the vehicle, the head no longer got caught. [Overview of the Challenge] - The size of this compact vehicle is smaller than conventional products, and each component is required to be miniaturized and lightweight. - Although truss screws are typically used for fastening, the design calculations indicated that the protruding head would interfere with other components inside the housing. - The space on the vehicle side for inserting the housing is also narrow, and with truss screws, the protruding head would get caught and not fit. *For more details, please refer to the related links or feel free to contact us.

[Case Study] Investigation and Manufacturing of Special Screws from a Factory that Went Out of Business and Became Unknown

[Case Study] Investigation and Manufacturing of Special Screws from a Factory that Went Out of Business and Became Unknown

From detailed investigation to product manufacturing, we offer one-stop support! Our strength lies in the ability to calculate setting values immediately.

We would like to introduce a case where we proposed the clarification of details for special screws, which became unclear due to the closure of a factory, using knowledge of drawing production and inspection tools in the plant maintenance industry. During the maintenance of a rod mill, the screws used became unavailable, making maintenance impossible. After our proposal, we were able to manufacture screws identical to the samples by selecting a manufacturing method according to the size and shape of the screws. [Overview of the Issue] - The factory that was commissioned to manufacture the special-shaped screws went out of business, resulting in the unavailability of screws needed for maintenance of the rod mill. - The only remaining item was a sample of the screw, which provided information only about its shape and material, as well as rough dimensions. - Three sizes of screws were needed in the quantities listed below by the maintenance scheduled to start in four months, and without these screws, maintenance of the rod mill could not be performed. *For more details, please refer to the related links or feel free to contact us.*

Strengthening Manual for Screws (Vol. 8) Differentiating Between Binding Heads and Flat Heads

Strengthening Manual for Screws (Vol. 8) Differentiating Between Binding Heads and Flat Heads

Introducing the distinction between bind head and flat head in a blog format!

In terms of head size, the bind head is between the pan head and the truss head (not exactly in the middle). It can be used when the truss head is too large for the workpiece, but the pan head might cause it to sink into the material. Additionally, since the depth of the cross hole is slightly deeper than that of the pan head depending on the screw diameter, it can be said that the cross hole is less likely to be damaged in theory. Next, regarding the flat head, its main feature is that after tightening, the head does not protrude from the workpiece and becomes flat. *You can view the detailed content of the blog through the related links.

Strengthening Manual for Screws (Vol. 7) Differentiating Between Pan Head and Truss Head

Strengthening Manual for Screws (Vol. 7) Differentiating Between Pan Head and Truss Head

Introducing the distinction between bowl heads and truss heads in a blog format!

Next, let's discuss the differentiation in the use of screws with heads. As representative examples, we will look at small screws with a cross recess and bolts with a hexagon socket. First, let's consider the small screw with a cross recess. In this category, let's take the "pan head," which has the highest shipment volume at Ikekin, as our standard. By using a truss head, which has a larger diameter than the pan head, the seating surface, which is the contact area between the screw and the counterpart material, becomes more stable, and the tendency for the screw to sink into the counterpart material is alleviated. *For more detailed information, please refer to the related links on the blog. Feel free to contact us for further inquiries.

Cost considerations for bolts, screws, tapping screws, and drill screws.

Cost considerations for bolts, screws, tapping screws, and drill screws.

Strengthening Guide for Screws (Vol. 6)! Introducing the concept of costs for bolts and screws in a blog format!

Next, from the perspective of cost, in order from lowest to highest, it goes as follows: drill screws → tapping screws → bolts and small screws. The cost referred to here is not only the cost of the screws themselves but also includes the expenses for the work necessary for fastening, commonly known as labor costs, which encompasses direct labor costs. This is largely influenced by the number of processes involved. Drill screws can be fastened directly without any pilot holes or internal threads, so roughly speaking, it can be done in one process. *For more detailed content of the blog, you can view it through the related links.

Differentiating between bolts, small screws, tapping screws, and drill screws.

Strengthening Guide for Screws (Vol. 5)! Introducing the differentiation between bolts and screws in a blog format!

Now, let's go through the eight items that make up a screw, one by one. I believe that such diligent work is necessary at the beginning of screw selection. This allows for the appropriate use of different screws. The keyword for this series of columns titled "Screw Strengthening Guide" is "appropriate use." First, let's discuss screw shapes. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

Strengthening Manual for Screws (Vol. 3) What is Basic Information about Screws?

Introducing basic information about screws in a blog format!

The structure of a screw consists of the following three basic pieces of information: type, material, and size. This applies universally to any object. To slightly deviate from the topic of screws, if we consider canned coffee, it would look something like this. *You can view the detailed content of the blog through the related links.

Screw Reinforcement Book (Vol. 12) is also working hard on the slotted type!

Screw Reinforcement Book (Vol. 12) is also working hard on the slotted type!

Introducing the benefits of grinding in a blog format!

In recent years, it has become quite rare to see, but slotted screws have advantages that other recesses do not have. For example, when adjusting screws for liquids, gases, or the position of objects, if you rotate it 90 degrees to the right, the appearance remains the same for cross slots, hex slots, and hexagonal sockets, but in the case of slotted screws, the appearance shows a vertical or horizontal line, making it immediately obvious when rotated 90 degrees. *You can view the detailed content of the blog through the related links.

What kind of screws are prone to seizing? Part 2

What kind of screws are prone to seizing? Part 2

I will introduce easily seizing fasteners in a blog format!

Let's take a look at what types of fastenings are prone to seizing. When the pitch of the screw is small, the pitch of fine-thread screws is, of course, smaller than that of coarse-thread screws. As the pitch decreases, the friction coefficient increases, making it more susceptible to heat, which in turn makes it more likely to seize. When the tightening speed is fast, electric tools with high rotation speeds generate friction heat more easily compared to manual tools, making them more prone to seizing. *You can view the detailed content of the blog through the related links.

Why do stainless steel screws tend to seize up easily?

Why do stainless steel screws tend to seize up easily?

I will introduce thermal conductivity and thermal expansion rate in a blog format!

The phenomenon where screws expand due to the frictional heat generated when tightening or loosening them, causing the male and female threads to seize and become immovable, is called "seizing." Seizing is also referred to as "galling," and stainless steel, in particular, has a tendency to seize easily due to its inherent properties. The causes of this are attributed to its low thermal conductivity and high thermal expansion rate. *For more detailed information, please refer to the related links.

How do you use martensitic stainless steel?

How do you use martensitic stainless steel?

Introducing treatments for martensitic stainless steel that do not reduce corrosion resistance!

13-chromium martensitic stainless steel has a lower chromium content than ferritic types, which reduces its corrosion resistance; however, one of its characteristics is that it can be hardened through quenching, or heat treatment. So, what types of screws need to be hardened when using stainless steel? A representative example is drill screws. Drill screws need to be hardened because they require a drill at the tip to create a pilot hole. *For more details, please refer to the related links. Feel free to contact us for more information.*
