Professional Applications & Engineering Value

This 5/16"-18 UNC elevator bolt is engineered to solve critical challenges in material handling and industrial machinery. The 18-8 Stainless Steel composition delivers excellent resistance to rust and corrosion, making it suitable for elevators, conveyor systems, and outdoor equipment exposed to moisture. The ribbed neck prevents spinning during installation, a common issue with smooth-shank bolts, ensuring the wide flat head remains securely seated. With a coarse thread and Class 2A thread fit, it provides quick, reliable fastening in high-vibration environments, reducing maintenance downtime. Its 100,000 PSI tensile strength and Rockwell B80 hardness offer durability against shear and tensile stresses, providing long-term reliability for industrial fasteners in demanding settings.

Specification Summary & Compliance

This elevator bolt adheres to Unified Standard Class 2A thread fit and UNC coarse thread specifications, ensuring precise dimensional accuracy and interchangeability. It is manufactured from 18-8 Stainless Steel with a tensile strength of 100,000 PSI and Rockwell B80 hardness. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, confirming it is free of hazardous substances and safe for industrial use.
