Professional Applications & Engineering Value

These black-oxide alloy steel rounded head screws deliver critical vibration resistance in machinery, automotive, and heavy equipment applications where loosening under dynamic loads is a major concern. The nylon patch thread locker creates permanent friction that prevents back-off without damaging threads, while the coarse UNC threading and Class 3A fit ensure rapid assembly with minimal cross-threading risk. The combination of 120,000 psi tensile strength and fully threaded design provides uniform stress distribution, making these hex drive screws ideal for structural connections subjected to constant vibration and thermal cycling from -70° to 250° F.

Specification Summary & Compliance

Manufactured to precise Class 3A thread fit tolerances with UNC 3/8"-16 coarse threading and full compliance with ASME B18.3, ASTM F835, and MIL-DTL-18240 specifications. These screws meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards, ensuring they contain no restricted substances for global industrial use.
