Professional Applications & Engineering Value

These 10-24 UNC partially threaded flat head screws deliver critical engineering advantages in demanding industrial applications. The passivated 18-8 stainless steel construction provides outstanding corrosion resistance, making them ideal for machinery, marine equipment, and outdoor installations where environmental exposure is a concern. The coarse thread spacing and partial threading design ensure maximum grip strength while reducing material stress concentration. With Rockwell B80 hardness and 80,000 psi tensile strength, these fasteners maintain structural integrity in high-vibration environments. The oval head profile with 82° countersink angle creates seamless surface finishes while the Phillips No. 2 drive enables efficient installation in confined spaces.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 2A thread fit tolerance for consistent performance. Thread specifications include 10-24 UNC coarse spacing with minimum 1½" thread length. Fully compliant with ASME B18.6.3 manufacturing standards, RoHS 3 (2015/863/EU) environmental directives, and REACH (EC 1907/2006) chemical safety regulations. The passivated surface treatment enhances corrosion protection while maintaining the material's inherent strength characteristics.
