Professional Applications & Engineering Value
This 1/4"-20 UNC elevator bolt is engineered to solve critical challenges in material handling and industrial assembly. The ribbed neck design is a key feature, mechanically locking the bolt in place to prevent spin-out in conveyor systems, elevator buckets, and machinery platforms where vibration is a constant issue. Manufactured from steel and finished with a protective zinc plating, it resists corrosion, reducing maintenance frequency and replacement costs. The coarse UNC thread and fully threaded shank allow for deep engagement and rapid installation, which is vital for production line efficiency. Its SAE Grade 2 strength ensures it can handle the significant shear and tensile loads common in these heavy-duty industrial applications, providing a dependable, long-lasting fastening solution.
Specification Summary & Compliance
This elevator bolt conforms to Unified Standard Class 2A thread fit for consistent dimensional accuracy and interchangeability. It is manufactured to UNC thread standards with a size of 1/4"-20. The product is REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliant, meeting stringent environmental and safety regulations for use in various markets.
