S-94105A532 1/4"-20 x 3/16" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments
• Exceptional holding power from Class 3A thread fit, ensuring vibration-resistant, secure fastening in critical assemblies
• High-strength durability with Rockwell C45 hardness alloy steel, resisting deformation under heavy loads
• Easy installation and removal using standard 1/8" hex drive tools, reducing assembly time and maintenance efforts
• Reliable flat tip design that minimizes surface damage while providing maximum contact pressure
• Wide compatibility with UNC coarse threads (1/4"-20), fitting common industrial components and equipment
• Headless construction allowing flush mounting in confined spaces without protrusion interference

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical performance where vibration resistance and precise alignment are paramount. The Class 3A thread fit maintains tight tolerances in UNC coarse threading, preventing loosening in high-stress applications like machinery shafts, gear assemblies, and precision tooling. The flat tip design distributes clamping force evenly, protecting component surfaces while the hex drive enables high-torque installation. Engineered for industrial set screws applications, it solves common challenges of component slippage, corrosion-induced failure, and maintenance accessibility in confined spaces.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with Class 3A thread fit precision and UNC 1/4"-20 coarse thread spacing. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in regulated industries. The Rockwell C45 hardness and precise dimensional controls guarantee consistent performance across production runs.
