S-94025A151 3/8"-16 x 3/8" ASME B18.6.2 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional holding power through the cup point tip design that bites into shafts for secure, permanent positioning
• Reliable installation and removal with standard slotted drive, compatible with common hand tools
• Optimized thread engagement with Class 2A thread fit and coarse UNC threads for faster assembly and vibration resistance
• Enhanced durability from Rockwell B80 hardness, maintaining structural integrity under repeated torque
• Space-saving headless design allowing flush mounting in confined assemblies
• Broad regulatory compliance meeting ASME B18.6.2, RoHS 3, and REACH for global supply chain integration

Professional Applications & Engineering Value

This 3/8"-16 UNC set screw is engineered to address critical challenges in industrial assembly, where component slippage and corrosion can compromise machinery performance. The 18-8 stainless steel material provides excellent resistance to rust and chemical exposure, extending service life in demanding settings like automotive, marine, or food processing equipment. Its cup point tip concentrates pressure to create a permanent locking effect on shafts, pulleys, and collars, preventing rotational or axial movement even under high vibration. Combined with coarse thread spacing and Class 2A thread fit, the screw ensures quick, precise installation with reduced risk of cross-threading, making it a reliable choice for maintenance and OEM applications requiring repeatable, secure fastening solutions.

Specification Summary & Compliance

This set screw adheres to ASME B18.6.2 specifications, with UNC 3/8"-16 coarse threads and Class 2A tolerance for consistent dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. The product meets defined standards for thread diameter (0.375"), length (3/8"), and hardness (Rockwell B80), supporting quality assurance in regulated industries.
