- High torque capability through Rockwell C45 hardness, preventing stripping under heavy mechanical loads
- Space-saving installation with headless hex drive design, ideal for confined spaces and flush-mount applications
- Quick assembly efficiency using UNC coarse threads and 3/16" hex drive, reducing installation time
- Reliable component protection with cup tip design, minimizing surface damage to secured parts
- Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and corrosion protection are critical. The Class 3A thread fit maintains precise tolerances in machinery, automotive, and manufacturing equipment, preventing loosening under continuous operation. The headless hex drive configuration allows flush mounting in pulleys, gears, and collars where protruding fasteners are impractical. With UNC coarse threads providing rapid installation and the cup tip distributing clamping force evenly, this set screw solves common challenges of component slippage and surface marring in high-torque applications.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision for superior dimensional accuracy. The 3/8"-16 UNC coarse thread pattern ensures reliable engagement, while the 2 3/4" length provides optimal fastening depth. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, alongside material certification to ASTM F912 standards for consistent quality and performance in industrial settings.
