Due to the effects of tightening force, the outer diameter triangle has shifted to a hexagon! Completion of the work can be confirmed visually.
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 displaces into a hexagon. When the end of the nut side contacts the nut and expands, the installation is complete. Additionally, this causes pressure to be applied to the nut by the three sides of the spring. 【Features】 ■ Loosening prevention effect from the spring's tightening force and pressure ■ 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.
