S-92695A817 1/2"-13 x 3" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Maximum holding power with Class 3A thread fit for secure, vibration-resistant fastening in demanding applications
• Superior corrosion resistance from black-oxide alloy steel, extending service life in harsh industrial environments
• Enhanced grip and alignment with 90° cone point design that bites into materials to prevent component slippage
• High-strength durability with Rockwell C45 hardness to withstand heavy loads and repeated adjustments
• Easy installation and removal using 1/4" hex socket drive for efficient maintenance with standard tools
• Reliable thread engagement with UNC coarse threads providing quick assembly and reduced cross-threading risk
• Industry-standard compliance meeting ASME B18.3 specifications for consistent performance and interchangeability

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional engineering value for industrial applications requiring permanent positioning and torque transmission. The 90° cone point creates concentrated pressure that digs into shaft materials, effectively preventing rotational movement in pulleys, gears, and collars. The UNC coarse threads combined with Class 3A thread fit ensure precise engagement while accommodating minor misalignments in manufacturing. The headless design with hex socket drive allows flush mounting in confined spaces where protruding fasteners are impractical. Manufactured from alloy steel with Rockwell C45 hardness, this set screw maintains its mechanical properties under continuous vibration and heavy loads, making it ideal for machinery, automotive, and power transmission systems where reliability is critical.

Specification Summary & Compliance

This set screw features 1/2"-13 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and tight tolerances. The 3" length and 0.5" thread diameter provide optimal engagement depth for various applications. Manufactured according to ASME B18.3 specifications, this fastener ensures consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial markets with strict chemical substance restrictions.
