Professional Applications & Engineering Value
This zinc-plated steel flat head screw delivers critical performance advantages for industrial assembly applications where vibration resistance and long-term reliability are paramount. The combination of UNC coarse threading and Class 2A thread fit ensures secure fastening in materials where fine threads might strip or fail. The 82° countersink angle provides optimal flush mounting in predrilled holes, eliminating protrusions that could interfere with moving components. With full threading along the entire 3-inch length, this fastener offers maximum grip range for variable material thicknesses. The zinc plating creates a protective barrier against corrosion, making these slotted screws ideal for machinery, electrical enclosures, and structural applications where environmental factors could compromise fastener integrity.
Specification Summary & Compliance
This 6-32 x 3" flat head screw features precise Class 2A thread fit tolerances and UNC coarse thread spacing manufactured to ASME B18.6.3 specifications. The fastener maintains dimensional accuracy with standard 82° countersink angle and right-hand thread direction. Compliance is verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for industrial applications with strict material restrictions.
