- Optimized drive transfer through tamper-resistant Torx design, minimizing cam-out during high-torque applications
Professional Applications & Engineering Value
These black-oxide alloy steel rounded head screws address critical engineering challenges in industrial fastening where security, corrosion resistance, and mechanical reliability are paramount. The 8-32 UNC Class 3A thread configuration ensures precise fitment in coarse-thread applications, while the tamper-resistant T15 Torx drive provides enhanced security against unauthorized disassembly in public infrastructure, electrical enclosures, and machinery guards. The combination of 130,000 psi tensile strength and Rockwell C38 hardness delivers exceptional fatigue resistance in vibration-prone environments, making these fully threaded screws ideal for automotive assemblies, industrial equipment, and telecommunications infrastructure where long-term fastener integrity is critical.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread tolerance for superior fit and UNC coarse thread spacing (8-32 size). Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features include 0.312" head diameter, 1/4" length, right-hand thread direction, and fully threaded design with 0.164" thread diameter.
