• Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use

Professional Applications & Engineering Value

This 6-32 UNC set screw delivers critical engineering solutions for industrial applications requiring precise component positioning and rotational force transmission. The zinc plated alloy steel construction combats corrosion in machinery, automotive, and electrical assemblies, while the Class 3A thread fit and coarse thread spacing ensure rapid installation with minimal cross-threading risks. The headless design and 1/16" hex drive allow flush mounting in tight spaces, and the cup tip concentrates clamping force without damaging shafts or gears. Engineered to prevent loosening under vibration, it offers reliable performance in heavy-duty set screw applications where precision and durability are paramount.

Specification Summary & Compliance

This set screw maintains Class 3A thread fit per UNC standards with 6-32 thread size and 0.138" diameter, ensuring precise dimensional accuracy. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for restricted substance-controlled industries.
