Anti-loosening washer (NORD-LOCK)

Safety, no special tools required, maintenance and inspection possible! Sizes available from M3 to M42.

The "NORD-LOCK washer" is a loosening prevention washer that secures bolts using tension rather than friction resistance. This system consists of a pair of washers, one with a cam surface and the other with a radial rib surface. The angle of the cam (α) is designed to be larger than the lead angle of the screw (β), making it difficult to easily overcome the cam. The wedge effect created by the cam surfaces prevents loosening of the bolt due to rotation. 【Features】 - Prevents loosening caused by intense vibrations and fluctuating loads, ensuring safe fastening. - Can be quickly and easily installed and removed with standard tools. *For more details, please refer to the PDF document or feel free to contact us.

Water leak prevention washer

Strongly bonded with metal and rubber through vulcanization! Sizes available from M1 to M20.

In fastening, there are many cases where the flexibility and adhesion of rubber are utilized to provide sealing or cushioning functions. However, since rubber alone cannot maintain strength, backup and holding power from metal washers are necessary, which affects cost performance. The "Leak-Proof Washer" has a strong adhesive force due to the vulcanized bonding of metal and rubber, resulting in minimal rubber escape during fastening. This prevents rubber from being caught in the threaded part, maintaining high sealing performance, as well as providing various functions such as vibration resistance, loosening prevention, shock absorption, surface scratch prevention, and insulation. Additionally, in relation to this product, Azuma Screw also offers "Leak-Proof Screws (Nuts)." 【Features】 ■ Strong adhesion of metal and rubber through vulcanized bonding ■ Material: Metal part (stainless steel), rubber part (neoprene, EPDM, etc.) ■ Size: M1 to M20 *For more details, please refer to the PDF document or feel free to contact us.
