S-92311A631 3/8"-16 x 2" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
• Maximum holding power and vibration resistance due to the Class 3A thread fit and coarse UNC thread spacing.
• High-strength and durability provided by Rockwell B80 hardness, preventing deformation under heavy loads.
• Secure, non-slip fastening enabled by the cup tip design, ensuring a firm grip on mating surfaces.
• Easy installation and removal with the 3/16" hex drive, allowing for efficient assembly in tight spaces.
• Reliable performance in critical applications as it meets ASME B18.3 specifications for dimensional accuracy.
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental standards.

Professional Applications & Engineering Value

This 3/8"-16 UNC Class 3A set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. Made from 18-8 stainless steel, it offers excellent resistance to rust and chemicals, making it suitable for machinery, automotive, and outdoor equipment. The headless design with hex drive allows for flush mounting in confined areas, while the cup tip ensures a secure bite into shafts or collars, preventing loosening under vibration. Its coarse thread spacing and right-hand thread facilitate quick installation, reducing assembly time in high-volume production. Ideal for precision set screws in heavy-duty fastening, this product enhances reliability in dynamic industrial environments.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including UNC thread type, 3/8"-16 thread size, and Class 3A thread fit for tight tolerances. It is manufactured in compliance with ASME B18.3 specifications and meets environmental regulations such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring safety and sustainability in industrial applications.
