The "Return Lock Bolt" is a counter-rotation prevention bolt that allows for one-handed operation without the need for welding or press-fitting, thanks to its unique neck shape design. It resolves the issue where the bolt would rotate together with the nut during installation, making it impossible to proceed with the work unless the bolt is held in place with one hand. 【Features】 ■ The peel strength after nut tightening is comparable to JIS welding bolts. ■ It does not select the substrate material of the counterpart. *For more details, please download the PDF or feel free to contact us.
