Professional Applications & Engineering Value

This 1/4"-20 UNC fully threaded elevator bolt is engineered to address critical challenges in material handling and industrial assembly. The 18-8 stainless steel material offers outstanding corrosion resistance, making it suitable for elevators, conveyor systems, and machinery exposed to moisture or chemicals. The square neck design prevents rotation when installed, a common issue in vibrating equipment, while the coarse threading ensures faster installation and reduced cross-threading risks. With a flat head profile and fully threaded shank, it provides uniform clamping force and ease of access in tight spaces, enhancing operational efficiency and equipment longevity in demanding industrial environments.

Specification Summary & Compliance

This elevator bolt adheres to Unified Standard Class 2A thread fit and UNC coarse thread specifications, ensuring precise dimensional accuracy and compatibility. It meets REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliance standards, confirming its safety and environmental responsibility. Manufacturing follows strict guidelines for 18-8 stainless steel hardness (Rockwell B80) and tensile strength (70,000 psi), providing reliable performance in accordance with industrial fastener requirements.
