S-92220A252 3/8"-16 x 3/4" ASTM A574 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating for extended service life in harsh industrial environments
• Maximum torque transmission through hex socket drive design prevents stripping and ensures secure installation
• Precision thread engagement with Class 3A fit provides reliable, vibration-resistant fastening in critical applications
• Exceptional mechanical strength with 140,000 psi tensile strength and Rockwell C39 hardness for heavy-duty load requirements
• Space-saving low-profile design allows installation in confined areas where standard socket heads won't fit
• Full thread coverage along the entire 3/4" length enables adjustable positioning and maximum grip length
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These black-oxide alloy steel socket head cap screws deliver exceptional performance in demanding industrial settings where reliability is non-negotiable. The 3/8"-16 UNC coarse thread configuration combined with Class 3A precision fit ensures rapid assembly while maintaining vibration resistance in machinery, automotive, and heavy equipment applications. The low-profile socket head design solves clearance issues in compact assemblies without compromising on the 140,000 psi tensile strength required for structural integrity. Manufactured to ASTM A574 specifications, these fully threaded fasteners provide consistent performance across production runs, making them ideal for OEM applications where dimensional stability and repeatability are critical engineering requirements.

Specification Summary & Compliance

This 3/8"-16 UNC low socket head cap screw features precise Class 3A thread fit with coarse thread spacing and right-hand thread direction. The fastener meets ASTM A574 manufacturing standards and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. With a 3/4" length and 3/16" hex drive, these screws maintain dimensional accuracy across all critical parameters including head diameter (9/16"), head height (0.188"), and thread diameter (0.375"), ensuring reliable performance in precision assembly applications.
