• Full-length coarse threading (UNC 1/4"-20) provides maximum grip and engagement length for secure fastening with included nut
• Precision Class 2A thread fit guarantees smooth assembly and consistent performance in high-vibration industrial environments
• Rockwell B80 hardness rating delivers excellent wear resistance and durability for long service life in demanding applications
• Complete compliance with REACH and RoHS 3 environmental standards ensures safe use in regulated industrial settings
• Right-hand threading with unified standards enables quick installation and compatibility with standard industrial equipment

Professional Applications & Engineering Value

This heavy-duty elevator bolt solves critical engineering challenges in material handling systems where vibration resistance and load distribution are paramount. The fully threaded UNC coarse threading combined with the wide flat head profile creates an optimal solution for elevator buckets, conveyor systems, and industrial machinery that experience constant movement and stress. The SAE Grade 2 steel construction with 70,000 psi tensile strength ensures these fasteners withstand the repetitive impacts and dynamic loads common in elevator and conveyor applications, while the Rockwell B80 hardness provides exceptional resistance to wear and deformation. The complete threading allows for adjustable positioning and maximum thread engagement with the included nut, creating a secure fastening system that maintains integrity in high-vibration environments.
