S-92610A106 4-40 x 3/8" ASTM A574 Torx Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP10 drive for reduced cam-out and extended tool life
• Exceptional tensile strength of 180,000 psi withstands extreme mechanical loads in demanding applications
• Enhanced corrosion resistance from black-oxide coating prolongs service life in harsh environments
• Precise Class 3A thread fit ensures reliable engagement and vibration resistance in critical assemblies
• Optimized hardness at Rockwell C39 provides excellent wear resistance without brittleness
• Regulatory compliance with RoHS 3 and REACH eliminates supply chain restrictions for global projects
• Standard UNC coarse threading enables quick installation and compatibility with common components

Professional Applications & Engineering Value

Engineered for precision assemblies requiring high clamp load retention, these socket head cap screws solve critical fastening challenges in aerospace, automotive, and heavy machinery applications. The black-oxide alloy steel construction combined with Torx Plus drive system prevents stripping under high torque conditions, while the Class 3A thread fit maintains dimensional stability in vibrating environments. The 180,000 psi tensile strength ensures joint integrity in structural components, making these fully threaded fasteners ideal for applications where failure is not an option. Their compliance with international standards guarantees consistent performance across global supply chains.

Specification Summary & Compliance

Manufactured to ASTM A574 specifications with Class 3A thread fit precision and UNC coarse threading. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility. The black-oxide surface treatment provides additional corrosion protection while maintaining dimensional accuracy across the 3/8" length and 4-40 thread size.
