Professional Applications & Engineering Value

These 10-24 UNC rounded head screws deliver critical engineering advantages in demanding industrial environments. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, automotive assemblies, and outdoor equipment where environmental exposure compromises fastener integrity. The Torx Plus IP25 drive system addresses common installation challenges by eliminating cam-out issues that damage drive interfaces and compromise torque accuracy. With Class 3A thread fit and coarse threading, these fasteners maintain secure connections in high-vibration applications while the rounded button head profile offers streamlined installation in space-constrained assemblies. The combination of 120,000 psi tensile strength and Rockwell C39 hardness ensures reliable performance in structural applications where fastener failure is not an option.

Specification Summary & Compliance

Manufactured to exacting ASME B18.3 standards with Class 3A thread fit precision for superior engagement and load distribution. These 10-24 UNC coarse thread screws maintain dimensional accuracy per inch system requirements with fully threaded design for maximum holding power. Compliance includes ASTM F835 specifications for mechanical properties, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) regulations governing chemical substances in industrial products.
