Insert nut "Keysert"

Insert nut "Keysert"

Reduced risk of pitch skipping during bolt tightening! A sturdy insert system that replaces wires.

The "Keysert" is an insert nut used for repairing and reinforcing crushed threaded holes. The insertion process does not require specialized tools and can utilize commercially available drills and taps. Additionally, after insertion is complete, the key that protrudes from the top can be driven into the groove with a specialized tool, creating a wedging effect. 【Features】 ■ Driving in the key prevents loosening of the insert and increases pull-out strength. ■ Since it is not a wire type, there is no concern about pitch skipping. ■ The drilling and tapping processes can use general tools instead of specialized ones. *For more details, please refer to the related links or feel free to contact us.

What kind of screws are prone to seizing? Part 1

What kind of screws are prone to seizing? Part 1

I will explain about screws that are prone to seizing in a blog format!

In terms of screw fastening itself, I will provide some examples of what tends to seize easily. For instance, in the fastening of hex bolts and hex nuts, when using JIS supplementary items such as JA hex nut type 1 and high nuts with greater height, the high nuts are more prone to seizing. In the case of high nuts, the grip length of the threads between the hex bolt and hex nut becomes longer, which increases the contact area between the male and female threads, generating friction heat more quickly and at a higher level. As a result, thermal expansion occurs, leading to the threads seizing. *For more detailed content of the blog, you can view it through the related links.

The strength classification of screws and the hardness classification of set screws are actually not used much!

The strength classification of screws and the hardness classification of set screws are actually not used much!

Strengthening Guide for Screws (Vol. 48)! Introduction to the strength classifications of steel nuts and stainless steel nuts.

The strength classification of steel nuts is represented only by numbers. There are eight types: "04," "05," "5," "6," "8," "9," "10," and "12," but in everyday use, they are rarely encountered based on my experience. The likely reason is that there are few, if any, commercially available products that clearly indicate the strength classification, which results in them being seldom used in daily orders and transactions. Please understand that this is solely my personal opinion. So, how are daily orders and transactions conducted? In the case of nuts, it is mostly done by material name rather than strength classification. *For more detailed content of the blog, please refer to the related links.

Insert nut "Ensat"

Insert nut "Ensat"

Recommended for soft materials! An insert with self-tapping functionality that offers excellent workability.

"Ensat" is an insert nut with a self-tapping feature. It eliminates the need for the tapping process required before inserting the wire insert. Furthermore, compared to press-fit types, the external thread section tightly grips the base material without gaps, making it less likely to come loose. 【Features】 ■ Can skip the pre-tapping process ■ Provides high pull-out strength due to its one-piece molding ■ Reduces distortion of the base material caused by insert insertion *For more details, please refer to the related links or feel free to contact us.

[Case Study] Elimination of Defects in Small Nuts and Visual Inspection Work

[Case Study] Elimination of Defects in Small Nuts and Visual Inspection Work

A case where the change of the manufacturing manufacturer and the mechanization of inspection reduced the defect occurrence rate.

We would like to introduce a case where we proposed "switching manufacturers/automating the bagging process" to a battery manufacturer. There was a frequent issue with the small-diameter brass hex nuts used in battery production, where "the taps were cut at an angle." After our proposal, and following audits of two manufacturers, product defects have not occurred since the process changes were approved. 【Case Overview】 ■ Issue - There was a frequent issue with the small-diameter brass hex nuts used in battery production, where "the taps were cut at an angle." ■ Requirements for Solving the Issue - Select manufacturers that can ensure accurate quality control (to prevent occurrence) - Ensure that defective products can be detected during the bagging and inspection processes (to prevent outflow) *For more details, please refer to the related links or feel free to contact us.
