Product Description

This hex socket head cap screw features knurling under the head and a pre-assembled nylon locking ring (Nylock) at the thread end. The nylon ring provides permanent prevailing torque – when engaged, the nylon is compressed, creating strong friction against vibration loosening. The knurling allows hand starting. Materials: 18-8 stainless steel (304) as well as SS316, SS316L, meeting ANSI/AISI standards and German A2/A4 grades with strength classes 70 or 80. This combination is ideal for applications requiring both vibration resistance and frequent assembly/disassembly, while offering stainless steel corrosion protection.

Applications
Industry Usage
Automotive High-strength applications in engines, heavy-duty machinery, and bridge construction
Mechanical Connecting mechanical parts, circuit boards, engines, transmissions in various industries
Energy Connecting power generation equipment and transmission lines
