Hex Socket Allen Key Metal Screw With Knurled Nylock 18-8 Stainless Steel Inox Ansi Aisi Ss 304 316 316l A2 A4 70 80 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
Food processing equipment – nylon ring prevents vibration loosening, A4 resists detergents. Medical diagnostic instruments – non-magnetic and locking. Outdoor traffic signal poles – resists wind-induced loosening. Automated production line locating fixtures – knurling for quick manual change. Marine deck fittings – 316L with nylon ring resists seawater and loosening. Key Features Nylon ring anti-loosening – reliable vibration resistance, reusable limited times. Knurling assistance – fast hand starting, improving efficiency. Stainless corrosion resistance – A4 grade for marine/chemical environments. Non-magnetic option – 304/316 austenitic grades are essentially non-magnetic. Dual convenience – anti-loosening plus manual operability.
