S-92765A408 5/16"-18 x 3/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating on alloy steel, extending service life in demanding industrial environments
• Precise Class 3A thread fit ensures tight, secure fastening with minimal vibration loosening in high-stress applications
• High Rockwell C45 hardness provides exceptional wear resistance and maintains thread integrity under repeated adjustments
• Headless hex drive design allows flush mounting in confined spaces while enabling high torque application with standard 5/32" hex keys
• Coarse UNC thread profile delivers faster installation and superior holding power in softer materials or where frequent adjustments are needed
• Oval tip configuration creates positive seating and reduces component marring compared to flat or cone point alternatives
• Full regulatory compliance including RoHS 3 and REACH ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

This 5/16"-18 UNC set screw delivers critical engineering solutions for industrial equipment maintenance and manufacturing applications. The black-oxide alloy steel construction combined with Rockwell C45 hardness provides exceptional resistance to corrosion and wear in harsh operating conditions. The headless hex drive design enables seamless integration where protruding fastener heads would interfere with moving components or require streamlined profiles. The Class 3A thread fit with coarse UNC threads ensures reliable performance in vibration-prone environments while the oval tip distributes clamping force evenly to prevent damage to shafts and collars. Ideal for securing gears, pulleys, and knobs on machinery, this industrial set screw meets the demanding requirements of maintenance, repair, and OEM assembly operations.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with Class 3A thread fit tolerance for precision engagement. Features 5/16"-18 UNC coarse threads with right-hand direction and 3/8" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and environmentally conscious manufacturing operations.
