Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 1/4-20 UNC elevator bolt combines 18-8 stainless steel durability with precision square neck architecture to solve critical fastening challenges. The fully threaded design accommodates variable material thicknesses in elevator systems, conveyor assemblies, and machinery guarding, while the coarse UNC threading maintains grip under sustained vibration. Its 70,000 psi tensile strength and corrosion-resistant properties ensure longevity in food processing, marine, and manufacturing applications where failure is not an option. The flat head profile with wide bearing surface distributes load evenly, preventing surface damage to connected materials.

Specification Summary & Compliance

This elevator bolt adheres to Unified Standard Class 2A thread tolerances with 1/4"-20 UNC coarse threading and right-hand thread direction. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives. Dimensional specifications include 3" length, 0.26" square neck width, and 31/32" head diameter, maintaining consistent performance across industrial fastening applications.
