Professional Applications & Engineering Value

These black-oxide alloy steel flat head screws deliver critical performance advantages in precision engineering applications where space constraints and corrosion resistance are paramount. The Torx Plus IP6 drive system addresses common assembly challenges by eliminating cam-out issues that can damage components during high-torque installation. With Class 3A thread fit and UNC coarse threading, these fasteners maintain consistent clamping force in vibration-prone environments while facilitating rapid assembly in production settings. The combination of 140,000 psi tensile strength and Rockwell C39 hardness ensures reliable performance in automotive, aerospace, and heavy machinery applications where fastener failure is not an option. The fully threaded design provides maximum engagement depth for critical structural connections.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with precise Class 3A thread tolerance for superior fit and function. The UNC 2-56 thread form with coarse spacing ensures optimal performance in various materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental responsibility. All dimensional characteristics including 0.197" head diameter, 82° countersink angle, and 3/8" length maintain strict adherence to industrial standards for consistent performance across applications.
