S-92610A144 6-32 x 1/4" ASTM A574 Torx Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments.
• Exceptional torque transmission via Torx Plus IP15 drive, reducing cam-out risk and tool wear for reliable fastening.
• High tensile strength of 180,000 psi ensures secure, vibration-resistant connections under heavy loads.
• Precise Class 3A thread fit guarantees consistent engagement and reduces cross-threading in assembly operations.
• Rockwell C39 hardness provides excellent wear resistance, maintaining thread integrity through repeated use.
• Fully threaded design allows for adjustable clamping force and versatile installation depths.
• Compliance with ASTM A574, RoHS 3, and REACH ensures material consistency and environmental safety for global supply chains.

Professional Applications & Engineering Value

This black-oxide alloy steel socket head cap screw with 6-32 UNC coarse threads and Torx Plus IP15 drive addresses critical challenges in machinery, automotive, and electronics assembly. The alloy steel construction combined with Class 3A thread fit minimizes loosening under vibration, while the black-oxide surface treatment resists rust in humid or corrosive settings. Engineers benefit from the high tensile strength and Rockwell C39 hardness for applications requiring repeated disassembly, such as jigs, fixtures, and precision equipment, where socket head design allows flush mounting in confined spaces.

Specification Summary & Compliance

Manufactured to ASTM A574 specifications, this screw features UNC coarse threads with Class 3A fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring adherence to environmental and safety regulations. The inch system measurements, including 1/4" length and 0.138" thread diameter, provide consistency for industrial fastener applications requiring reliable performance.
