Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating on alloy steel for extended service life in harsh environments
- Maximum holding security achieved through Class 3A thread fit ensuring tight, vibration-resistant connections
- Enhanced torque transmission with hex drive design preventing tool slippage during installation
- Deep penetration and superior grip from 90° cone point tip that bites into mating surfaces
- Exceptional durability with Rockwell C45 hardness maintaining structural integrity under heavy loads
- Reliable coarse threading with UNC pattern providing quick assembly and reduced cross-threading risk
- Space-saving headless design allowing flush mounting in confined applications
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance in demanding industrial applications where vibration resistance and positional security are paramount. The 90° cone point tip creates permanent seating impressions in shafts, collars, and pulleys, preventing rotational slippage in power transmission systems. Engineered with Class 3A thread fit and UNC coarse threading, it maintains precise alignment while accommodating minor material variations. The hex drive configuration ensures high torque application without cam-out, making it ideal for assembly lines and maintenance operations. Headless set screws like this are particularly valuable in rotating machinery, automotive components, and manufacturing equipment where protruding fasteners would interfere with operation.
Specification Summary & Compliance
This 3/8"-16 UNC set screw features precise Class 3A thread fit tolerances with coarse thread spacing for optimal engagement. Manufactured to ASME B18.3 specifications with Rockwell C45 hardness and 90° cone point angle. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. Dimensions include 7/16" length, 3/8"-16 thread size, and 3/16" hex drive.
