S-92695A814 1/2"-13 x 2 1/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in harsh industrial environments
• Exceptional holding power thanks to Rockwell C45 hardness and 90° cone point design that bites deeply into materials
• Precise Class 3A thread fit ensures tight tolerances and reliable fastening in critical applications
• Easy installation and removal with 1/4" hex drive design that prevents stripping and allows high torque application
• Optimized for heavy-duty use through coarse UNC threads that provide faster installation and superior vibration resistance
• Headless design enables flush mounting where space constraints or rotating components are concerns
• Regulatory compliance with ASME B18.3, RoHS 3, and REACH standards ensures environmental and safety adherence

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and permanent positioning are critical. The 90° cone point creates concentrated pressure that securely locks components onto shafts, preventing slippage in high-torque machinery, power transmission systems, and precision equipment. The Class 3A thread fit provides tighter tolerances than standard fasteners, ensuring precise alignment in assembly operations. Coarse UNC threads offer superior performance in softer materials and applications subject to vibration, while the headless design makes these set screws ideal for confined spaces and rotating assemblies where protruding fasteners would cause interference or safety hazards.

Specification Summary & Compliance

This high-performance fastener features 1/2"-13 UNC coarse threads with Class 3A fit for precision threading applications. Manufactured to ASME B18.3 specifications with Rockwell C45 hardness rating, the set screw maintains dimensional accuracy throughout its 2-1/4" length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while meeting international quality standards for industrial set screws.
