S-96075A187 10-32 x 1/2" ASME B18.3 Tamper-Resistant Torx Steel Button Head Screws

Key Features & Benefits at a Glance

• Superior tamper resistance with T25 Torx drive design, preventing unauthorized access in high-security environments.
• Exceptional tensile strength of 130,000 psi ensures reliable performance under heavy loads and vibration.
• Precise Class 3A thread fit delivers tighter tolerances for secure fastening and reduced risk of loosening.
• Corrosion-resistant black-oxide finish on alloy steel enhances durability in harsh industrial conditions.
• Fine UNF threading provides improved engagement and holding power in materials requiring fine pitch.
• Fully threaded shank allows for maximum grip along the entire length, ideal for varied material thicknesses.
• Rounded button head design offers a low-profile, aesthetically clean finish while minimizing snagging.

Professional Applications & Engineering Value

Engineered for demanding industrial and security applications, these 10-32 UNF Class 3A black-oxide alloy steel rounded head screws address critical challenges like tampering and mechanical stress. The tamper-resistant T25 Torx drive ensures only authorized personnel can install or remove the fastener, making them ideal for public infrastructure, electronics enclosures, and machinery requiring controlled access. The fine thread and Class 3A fit provide superior resistance to vibration loosening, while the black-oxide surface treatment on high-strength alloy steel combats corrosion, extending service life in outdoor or chemically exposed settings. Fully threaded for consistent clamping force, these screws deliver reliable performance in assembly lines, automotive components, and secure mounting systems where precision and durability are non-negotiable.

Specification Summary & Compliance

This product adheres to ASME B18.3 specifications for dimensional accuracy and thread form, with a Class 3A thread fit ensuring tight tolerances for unified fine (UNF) threads. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. Manufacturing meets industry standards for alloy steel material properties, including Rockwell C38 hardness and 130,000 psi tensile strength, supporting use in regulated and high-performance environments.
