Special Features

Integrated Wire Holes: Each screw features a pre-drilled cross-hole through the head, designed specifically for safety wiring (lock wiring) to prevent loosening under extreme vibration. Essential for aerospace, motorsports, racing, and high-performance machinery where fastener failure is not an option.
304 Stainless Steel Construction: Manufactured from corrosion-resistant 304 stainless steel, these bolts offer excellent durability and rust resistance for marine, automotive, and industrial applications in harsh environments. They withstand moisture, salt, and chemical exposure without degrading.
Precise Hex Head Dimensions: Features a standard 16.8mm across-flats hex head with 6.4mm thickness, compatible with standard 17mm wrenches and sockets for easy installation and removal. Provides reliable torque transfer without rounding or stripping.
Variable Pack Quantities: Comes in practical pack sizes scaled to length—4 pieces for shorter lengths (20-45mm), 3 pieces for medium lengths (50-60mm), and 2 pieces for longer lengths (80-100mm)—matching typical usage patterns and providing excellent value.
High-Vibration Applications: Ideal for securing critical components on motorcycles, race cars, boats, industrial machinery, aircraft, and any application where vibration-induced loosening must be positively prevented. Safety wire provides visual verification of proper fastening.
