Abstract

This product is a bolt or nut loosening prevention device that can prevent bolts or nuts from loosening due to rotation caused by vibration or other factors. This product consists of a plate-shaped base member, an engaging part that engages with the bolt or nut, and a screw hole through which a screw or the like passes. By engaging the bolt's screw head or nut with the engaging part and fixing the base member to building materials with a screw or the like, the loosening of the bolt or nut can be prevented.
