Professional Applications & Engineering Value

These 10-24 UNC flat head slotted screws deliver critical engineering solutions for industrial applications where reliable fastening and flush surface mounting are paramount. The zinc-plated steel construction provides essential corrosion protection in manufacturing environments, while the 60,000 PSI tensile strength ensures joints maintain integrity under vibration and load stress. The standard 82° countersink angle allows for perfect flush installation in predrilled holes, eliminating protrusions that could interfere with moving parts or create safety hazards. With coarse UNC threading and Class 2A thread fit, these screws offer excellent resistance to loosening in wood, plastic, and metal assemblies, making them ideal for machinery, electrical enclosures, and structural frameworks where vibration resistance is critical.

Specification Summary & Compliance

These flat head screws feature precise Class 2A thread fit with UNC coarse threading (10-24 size) and standard inch system dimensions including 0.362" head diameter and 1" length. Manufacturing and quality adhere to ASME B18.6.3 specifications for dimensional accuracy and performance reliability. The products are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors without hazardous substance restrictions.
