Key Features & Benefits at a Glance

  • Superior anti-rotation performance thanks to the integrated square neck design, preventing bolt spin during installation and ensuring secure, long-term fastening in high-vibration environments.
  • Enhanced corrosion resistance provided by the zinc plating, extending the bolt's service life in demanding industrial and warehouse settings.
  • Reliable tensile strength of 70,000 psi and Rockwell B80 hardness, offering dependable load-bearing capacity for medium-duty elevator and conveyor applications.
  • Easy and quick installation with coarse UNC threading and a fully threaded shank, allowing for faster assembly and disassembly.
  • Wide flat head profile for a larger bearing surface, distributing load more effectively and reducing the risk of surface damage.
  • Compliance with REACH and RoHS 3 standards, ensuring the product is free from hazardous substances and safe for use in regulated industries.
  • Precision threading with Unified Standard Class 2A fit guarantees consistent, reliable engagement with nuts for a secure connection.

Professional Applications & Engineering Value

This 3/8"-16 UNC Square Neck Elevator Bolt is engineered to solve common industrial challenges like component slippage and corrosion-induced failure. The square neck is a critical feature, embedding into the mounting surface to provide exceptional anti-rotation, which is vital for elevator systems, conveyor belts, and machinery where vibration can loosen standard fasteners. Made from SAE Grade 2 steel and finished with a protective zinc plating, it resists rust and wear in humid or abrasive environments. The coarse thread and fully threaded design ensure rapid installation and high pull-out strength, making it a reliable choice for securing wood, metal, and other materials in construction, manufacturing, and material handling equipment.

Specification Summary & Compliance

This elevator bolt features a 3/8"-16 UNC coarse thread with a Unified Standard Class 2A fit for dimensional accuracy and reliable mating. It is manufactured from SAE Grade 2 steel with a tensile strength of 70,000 psi and Rockwell B80 hardness. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring environmental and safety standards are met for industrial use.
