Self-clinching fasteners (press-fit fasteners) are a type of fastener that works by plastically deforming the material when pressed into a pre-drilled hole, causing it to bond securely. The sawtooth-shaped locking ring serves to prevent rotation. They provide stable, high fastening strength and a beautiful finish, and can also be used on thin sheets that are considered difficult for threading. 【Advantages】 ■ Cost-effective and environmentally friendly joining method ■ Strong load-bearing capacity for thin panels ■ Easy installation ■ Reduction in labor costs ■ Pull-out force and load torque ■ Clean appearance

• fastener

A rivet consists of a head and a body without threads (with some exceptions). It is inserted into a pre-drilled component and deformed on the opposite end using a specialized tool to create a fastening. Hand rivets that do not require tools have also been developed.

• fastener

• fastener

It can be installed seamlessly with a very high load capacity. There are two types available: one with a groove and one with three holes, providing various screw inserts according to the required fixing method. 【Features】 ■ It can be installed mainly on soft metals and alloys (such as aluminum, magnesium, zinc), plastics, and wood. ■ Thin-walled inserts are ideal for limited spaces and can also be screwed in by machine. ■ Pre-tapping is unnecessary; as long as a pilot hole is processed in the base material, it can be directly embedded.

By adopting high-strength bolt steel with excellent "delayed fracture resistance characteristics," we achieve a tensile strength of 1,400 N/mm² while realizing an elongation of over 9%. Furthermore, the use of aerospace-grade "MJ screws" results in a shallower valley at the screw section and a larger valley radius compared to standard specifications, which enhances fatigue resistance by alleviating the notch effect.

• fastener

**Features** ■ High Strength: 4 times the strength of SUS304 (A2-50), 2 times the strength of SUS316 (A4-70) ■ Corrosion Resistance: No corrosion observed even after 10 years of testing in marine environments ■ Heat Resistance: Maximum operating temperature in the atmosphere is 600°C ■ Non-Magnetic: Exceptional non-magnetism with a permeability of 1.006 (BUMAX 88) ■ Anti-Seizing: Friction coefficient during bolt tightening is less than 50% of SUS316 ■ Low Cost: Conversion of expensive nickel alloys to affordable BUMAX bolts ■ Environment: Reduces CO₂ and achieves a clean environment

SUS 304CUN is an austenitic stainless steel (A2) that boasts high strength (A2-90, A2-100), high heat resistance, high corrosion resistance, and non-magnetic properties, making it a strong and rust-resistant high-strength material. By adding copper (CU) and nitrogen (N), it is possible to increase strength while ensuring non-magnetic properties, and it has stress corrosion cracking resistance comparable to SUS 316. Furthermore, SUS 304N2, which is SUS 304 with added nitrogen (N) and niobium (Nb), is a stainless steel that enhances strength while minimizing the reduction in ductility. It is used in structural strength members and high-pressure vessels. High-strength stainless steel washers that can withstand A2-100 specifications using SUS 304N2 have also been created. These washers prevent plastic deformation (dimpling) around the holes of the mating components during tightening with high-strength fasteners, providing an anti-loosening effect.

The anti-seizing nut has high adhesion, making it difficult for the plating to peel off, allowing for repeated use. Additionally, the smooth tin plating finish reduces the friction coefficient of the screw surface and seating surface, increasing axial force, while the friction coefficient is not too low, thereby reducing the risk of over-torque compared to anti-seizing agents. 【Features】 ■ High anti-seizing and galling prevention effect: By applying a three-layer plating, not only is the anti-seizing effect achieved, but also improvements in aesthetics and adhesion strength. ■ Reusable: Unlike coating agents, the high adhesion of the plating makes it difficult to peel off, and even after repeating tightening tests eight times, the anti-seizing effect remains. ■ Clean: With a dry finish, there is no leakage like when using lubricants, preventing dirt. Furthermore, no application time is required, which shortens work time. ■ Cost reduction: The time required for replacing seized nuts can be reduced, leading to broad cost savings in labor costs, tool strain, and the risk of injuries related to the work.
