• Enhanced driving efficiency with external hex/slotted drive and flanged head, providing excellent torque transfer and eliminating the need for separate washers
• Reliable thread-cutting performance in tough materials like aluminum, brass, cast iron, and sheet metal without pre-tapped holes
• Secure fastening in coarse UNC threads with 8-32 size, offering strong holding power and vibration resistance in various assemblies
• Full threading along the 1" length ensures maximum grip and uniform stress distribution for consistent joint integrity
• Compliance with ASME B18.6.3 standards guarantees dimensional accuracy and mechanical reliability for professional applications
• RoHS 3 environmental compliance supports sustainable manufacturing practices and safe usage in regulated industries

Professional Applications & Engineering Value

These 8-32 UNC tapping screws are engineered to solve common assembly challenges in metalworking and fabrication. Made from zinc-plated steel, they resist rust and corrosion, extending service life in humid or outdoor settings. The thread-cutting design (Type F) and coarse UNC threads enable easy installation in aluminum, brass, cast iron, and sheet metal without stripping or pre-tapping, reducing labor time and tool costs. The flanged hex head distributes clamp load evenly, preventing surface damage and maintaining seal integrity in automotive, HVAC, and machinery assemblies. By integrating a fully threaded shank and compatibility with a standard No. 26 drill bit, these screws ensure precise, repeatable fastening for high-volume production lines.

Specification Summary & Compliance

This screw adheres to UNC thread standards with a size of 8-32, thread diameter of 0.164", and coarse spacing for robust engagement. Manufacturing follows ASME B18.6.3 specifications, ensuring consistent dimensions such as head width (1/4"), length (1"), and flange diameter (0.348"). It is fully compliant with RoHS 3 (2015/863/EU) regulations, confirming the absence of hazardous substances for safe industrial use.
