Professional Applications & Engineering Value

This square neck elevator bolt delivers critical engineering advantages in material handling and industrial applications where rotational stability is paramount. The SAE Grade 2 steel construction provides dependable strength for elevator systems, conveyor belts, and machinery platforms, while the zinc plated finish resists corrosion in humid or demanding environments. The integrated square neck design positively locks into mating surfaces, eliminating bolt rotation during nut tightening and preventing damage to soft materials. With fully threaded UNC coarse threading, installation is accelerated while maintaining secure fastening across the entire bolt length. These industrial fasteners solve common assembly challenges in wood, metal, and composite applications where standard bolts would rotate or require additional anti-rotation components.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Unified Standard Class 2A thread fit and 1/4"-20 UNC coarse thread specifications. Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations. Mechanical properties include 70,000 PSI tensile strength and Rockwell B80 hardness, meeting SAE Grade 2 strength classification requirements for reliable performance in industrial applications.
