S-92695A662 5/16"-18 x 1 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for tight, vibration-resistant connections in demanding applications
• Enhanced corrosion resistance thanks to the black-oxide finish on alloy steel, extending service life in industrial environments
• High-strength durability with Rockwell C45 hardness, preventing deformation under heavy loads
• Secure, deep penetration from the 90° cone point design, ensuring maximum grip on shafts and components
• Easy installation and removal with the 5/32" hex drive, allowing efficient maintenance with standard tools
• Reliable coarse threading (UNC) for quick assembly and reduced cross-threading risks in right-hand applications
• Compliance with industry standards including ASME B18.3, ensuring consistent quality and interchangeability

Professional Applications & Engineering Value

This 5/16"-18 UNC Class 3A set screw is engineered to solve common industrial challenges like component slippage and loosening under vibration. Crafted from black-oxide alloy steel, it offers excellent tensile strength and corrosion protection, ideal for machinery, automotive assemblies, and precision equipment. The headless design with a 90° cone point digs securely into materials, providing permanent positioning without protruding parts. Its coarse thread and hex drive simplify installation in tight spaces, reducing assembly time while maintaining high Rockwell C45 hardness for long-term reliability in heavy-duty applications.

Specification Summary & Compliance

This set screw adheres to precise Class 3A thread fit and UNC coarse thread standards with a diameter of 0.313" and 1 1/2" length. It meets ASME B18.3 specifications for dimensional accuracy and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
