秋野制作 Company Profile

Handling of locking bolts such as wave screw bolts (Japanese Patent Application No. 2014-90133) and left-right threaded bolts and nuts (Patent No. 5360848).

This describes the independently developed right and left-hand screws that exist as standalone bolts, as well as the non-loosening bolts with a lead shaped in a wavy pattern. The right and left-hand screw bolts have passed the NAS (National Aerospace Standards) anti-loosening test. Since these bolts use standard threads, there is no need for stress analysis such as finite element method, and the strength of the bolts can be confirmed as usual.
