The "Petal Fastener" is a dropout prevention spring that provides a loosening prevention effect through the tightening force and pressure of the spring. Due to the influence of the tightening force, the outer diameter triangle is displaced into a hexagon. When the end of the nut side contacts the nut and expands, the installation is complete. Additionally, this causes pressure against the nut from the three sides of the spring. 【Features】 ■ Loosening prevention effect due to the tightening force and pressure of the spring ■ Visual confirmation of installation completion ■ Can be installed on existing bolts and nuts ■ Available sizes range from M4 to M36 *For more details, please refer to the PDF document or feel free to contact us. Our representative will provide an explanation. 　　TEL: 06-6747-4450 　　Mail: kobori-f@info.ne.jp 　　To Shirayama
