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.

Slack Prevention Bolt, Nut, Washer 'ActiveX'

Achieves a skirt shape that does not sag. It is reusable and can also reduce costs.

"ActiveX" is a bolt, nut, and washer that realizes high anti-loosening functionality with a simple shape, based on the concept of "absorbing the force that loosens screws." The spring effect generated by the elastic deformation of the skirt section absorbs vibrations and shocks, demonstrating its anti-loosening effect. According to the NAS3350 standard, vibration tests were conducted using JQA's high-speed screw loosening testing machine, resulting in a finding that it does not loosen for 17 minutes. 【Features】 ■ The spring effect generated by the elastic deformation of the skirt section absorbs vibrations and shocks. ■ Special shape for full contact of the seating surface. ■ Excellent reusability, allowing for cost reduction. ■ Passed vibration tests under the NAS3350 standard for 30,000 cycles (17 minutes). *For more details, please refer to the PDF document or feel free to contact us.
