S-92695A682 1/2"-13 x 2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Class 3A thread fit for precise, vibration-resistant fastening in demanding applications
• Superior corrosion resistance from black-oxide coating on alloy steel, extending service life in harsh industrial environments
• Enhanced material durability with Rockwell C45 hardness providing excellent wear resistance and reduced thread deformation
• Optimal grip and alignment through 90° cone point design that digs into mating surfaces for secure component positioning
• Easy installation and removal with 1/4" hex drive in headless design, ideal for confined spaces and high-torque applications
• Reliable coarse threading using UNC 1/2"-13 specification for quick assembly and reduced cross-threading risks
• Full regulatory compliance meeting ASME B18.3, RoHS 3 and REACH standards for global industrial acceptance

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications requiring permanent component fixation. The Class 3A thread fit ensures exceptional dimensional accuracy that prevents loosening under vibration in machinery, automotive, and manufacturing equipment. The 90° cone point creates positive mechanical locking by penetrating into shaft surfaces, eliminating slippage in high-torque environments. Manufactured from alloy steel with Rockwell C45 hardness, this UNC coarse thread set screw maintains its structural integrity through repeated adjustments while the black-oxide finish provides essential corrosion protection. The headless hex drive design allows installation in space-constrained assemblies where traditional fasteners cannot operate effectively.

Specification Summary & Compliance

This 1/2"-13 UNC set screw features precision Class 3A thread fit with coarse thread spacing for optimal engagement. Manufacturing conforms to ASME B18.3 specifications (ASTM F912) ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for industrial fastener applications. Additional specifications include right-hand thread direction, 2" length, and 1/4" hex drive size for standardized tool compatibility.
