Professional Applications & Engineering Value

These 6-32 UNC flat head slotted screws provide critical solutions for industrial assembly challenges where flush surface mounting is essential. The zinc-plated steel construction combats corrosion in manufacturing environments, while the coarse thread design ensures superior holding power in wood, plastic, and sheet metal applications. With 60,000 psi tensile strength and Rockwell B70 hardness, these fully threaded fasteners maintain integrity in vibration-prone assemblies. The 82° countersink angle allows perfect seating in predrilled holes, making them ideal for machinery, electrical enclosures, and structural components requiring smooth, snag-free surfaces.

Specification Summary & Compliance

Manufactured to exact ASME B18.6.3 specifications with Class 2A thread fit tolerances for consistent performance. These 2-1/4" flat head slotted screws feature UNC coarse threads with right-hand orientation and standard head profile. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across industrial sectors.
