Professional Applications & Engineering Value
This steel elevator bolt with ribbed neck design addresses critical challenges in material handling and conveyor systems where vibration-induced loosening can cause operational failures. The zinc plated finish provides essential corrosion protection in environments exposed to moisture and chemicals, while the flat head with wide profile ensures flush mounting that won't damage conveyor belts or elevator components. Engineered with UNC coarse threading and full thread coverage, this SAE Grade 2 fastener delivers reliable performance in heavy-duty applications where consistent clamping force and vibration resistance are paramount. The combination of 70,000 psi tensile strength and Rockwell B80 hardness ensures durability under repetitive loading conditions common in industrial settings.
Specification Summary & Compliance
This elevator bolt features precision 1/4"-20 UNC coarse threads manufactured to Unified Standard Class 2A thread fit tolerances, ensuring consistent engagement and compatibility with standard nuts. The fastener meets SAE Grade 2 specifications with documented 70,000 psi tensile strength and is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards. Manufacturing follows established industrial standards for dimensional accuracy, including the standardized No. 3 elevator bolt profile with ribbed neck configuration for secure installation in conveyor and lifting applications.
