Professional Applications & Engineering Value
These black-oxide alloy steel rounded head screws address critical industrial challenges where security, corrosion resistance, and high tensile strength are paramount. The T27 tamper-resistant Torx drive provides reliable fastening in public infrastructure, electrical enclosures, and machinery requiring unauthorized access prevention. The black-oxide surface treatment creates a protective barrier against moisture and chemicals, significantly reducing maintenance in outdoor or corrosive environments. With fully threaded UNC coarse spacing and Class 3A thread fit, these screws ensure rapid installation and vibration resistance in assembly lines, automotive components, and industrial equipment where reliable fastening under stress is essential for operational safety and reduced downtime.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision tolerance. Features UNC 1/4"-20 coarse threads with fully threaded design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Meets 130,000 psi tensile strength and Rockwell C38 hardness requirements for industrial-grade performance.
