This is a pre-bolting torque type nut that incorporates a nylon washer into the female thread part of the nut, allowing the male thread of the bolt to form a female thread in that area, creating a friction fit that generates a large friction force. Since a nylon material (66 nylon) is used for the anti-loosening mechanism, its fatigue strength under load is higher than that of metal, allowing for several repeated uses. The use of a nylon ring in the female thread part of the nut ensures stable tightening torque and prevents damage to the counterpart bolt. 【Specifications】 ◆ Stainless steel SUSXM7 is used. ◆ The appearance features a glossy finish achieved through barrel polishing, with no chemicals used. ◆ The contact area is circular, preventing scratches on the fastened item. ◆ The use of a nylon ring for anti-loosening prevents damage to the threads of the counterpart. ◆ Repeated use is possible. *For more details, please contact us or download the PDF.
