This is a stainless steel hexagonal nut with a coarse thread that has been cut thinner and more compact than commercial products. Its thickness is approximately 40% thinner than Type 1 and even thinner than Type 3.
The hexagonal opposing sides are one size smaller than commercially available products, allowing for space-saving use. There is also an ultra-thin version that is processed even thinner than this product. The double nut of this product and the ultra-thin type is also effective for preventing loosening.
This is a stainless steel hex fine nut that has been machined to be thinner and more compact than commercially available products. Its thickness is about half that of type 1, and the hexagonal width is also smaller than that of commercially available products.
We also offer an ultra-thin version that is processed to be even thinner than this product. The double nut, consisting of this product and the ultra-thin version, is also effective for preventing loosening.
This is a nylon cosmetic nut that is strong, wear-resistant, has excellent lubricity and chemical resistance, and is oil-resistant.
The resin part is available in two colors: white and black.
By inserting this product into a round hole in a thin plate, you can create screw holes in metal plates, wood, etc., where screw processing is not possible.
The inner diameter has a fine thread hole, but coarse threads are also available in the lineup. It has a structure that tightens with a toothed washer and a hex nut without using a special tool. When using the included toothed washer, you can use it without worrying about loosening. Since it is a hex head type, it can be easily tightened with a wrench or similar tool.
This is a thin, compactly machined stainless steel hex unify nut.
We offer two types: UNF (coarse thread) and UNF (fine thread). They are finished to be approximately 30% to a maximum of 65% thinner than commercially available products, allowing for space-saving use. The hexagonal opposite sides are not in inch standards, so you can use a standard metric wrench. Using double nuts is also effective for preventing loosening.

Capable of simultaneous insertion of more than 10 units! Contributes to improved work quality, labor saving, and cost reduction! Leave the solution to insert nut challenges to us.
We offer the "Multi-Axis Simultaneous Heat Pressing Machine for Insert Nuts," which was developed from the concerns of small factories. This machine allows for the simultaneous pressing of multiple insert nuts while minimizing strain on the wrist, enabling work to be done without variations in quality or speed due to differences among operators. Customers can choose from automatic, semi-automatic, or manual options based on their needs. It is widely used by factory managers, quality control personnel, and pressing operators, and has received great acclaim due to the quick return on investment for the initial cost of the pressing machine. 【We solve the following issues】 - The tilt or height of insert nuts is unstable after pressing. - If one of multiple insertions fails, the workpiece becomes wasted. - The work takes a long time and puts strain on the hands. *For more details, please refer to the materials or feel free to contact us. If you wish to experience the machine, please apply through the <Contact Us> section, and we will bring a demo unit.
We will introduce a case that solved the issue of wanting to shorten the time required for the pressing operation!
Recently, the number of resin products has been steadily increasing. When producing resin products, various issues need to be considered, and we often receive challenges related to the heat insertion of insert nuts. This time, as we launched a new product, we addressed the customer's request to improve productivity due to the time-consuming process of inserting insert nuts. [Proposal] The conventional manual operation took 77 seconds per workpiece, so we proposed a manual simultaneous insertion machine that reduces the working time to about 35 seconds for four locations. [Result] Typically, two people were needed to handle mass production with the conventional soldering method, but with simultaneous insertion, one person can manage it. As a result, once the day's work is completed, the insertion machine can be easily moved to the edge of the desk or a shelf. Currently, we are producing 10,000 units per month, but due to the reduction in insertion work time per unit, we can now increase production to 16,500 units within the working hours. *For more details, please refer to the PDF or contact us.
