About This Product

Spring to prevent bolts and nuts from loosening and falling off.

■Features

1.Loosening effect due to spring tightening force and pressure The loosening effect is generated by the tightening force on the threaded part generated by attaching it to the bolt, and the pressure against the nut generated by pressing the nut surface with the three sides of the spring. 2. Visually confirm construction completion ・Due to the effect of tightening force, the triangle on the outer diameter is displaced into a hexagon. - Installation is complete when the end on the nut side contacts the nut, expands in diameter, and becomes parallel to the nut. Also, this causes pressure on the nut on three sides of the spring. 3.Can also be installed on existing bolts and nuts Installation is possible if the bolt has at least 5 turns of extra length. For new installations, insert the pedal fastener and nut into the 12-sided socket in that order, allowing for integrated installation. The spring structure allows for smooth construction. *Other model numbers are available
