• Exceptional anti-rotation performance due to the square neck design, preventing bolt loosening under vibration
• Reliable load distribution from the wide flat head, minimizing surface damage and pull-through
• Consistent tensile strength of 70,000 psi with SAE Grade 2 rating, ensuring dependable performance in low-strength applications
• Easy installation and alignment with fully threaded UNC coarse threading and Class 2A fit
• Enhanced durability from Rockwell B80 hardness steel construction, resisting deformation
• Complete assembly solution with included nut, reducing sourcing time and ensuring part compatibility

Professional Applications & Engineering Value

This 5/16"-18 UNC elevator bolt is engineered to solve critical challenges in material handling and industrial assembly. The square neck securely locks into mating surfaces, eliminating rotation in conveyor systems, elevator buckets, and machinery platforms where vibration-induced loosening causes operational failures. Manufactured from steel with zinc plating, it resists rust in humid or outdoor conditions, while the wide flat head distributes clamping force over a larger area, preventing damage to wood or composite materials. With SAE Grade 2 strength and coarse threading, it provides reliable fastening in low-to-moderate stress applications, ensuring long-term performance without premature wear or replacement.

Specification Summary & Compliance

This elevator bolt meets Unified Standard Class 2A thread fit with 5/16"-18 UNC coarse threads and fully threaded design. It conforms to SAE Grade 2 standards with 70,000 psi tensile strength and Rockwell B80 hardness. The product is fully REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliant, ensuring adherence to international environmental and safety regulations for industrial components.
