Professional Applications & Engineering Value

This 7/16"-20 UNF hex head screw delivers critical performance advantages in demanding industrial fastening applications. The 18-8 stainless steel composition provides superior corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements. The UNF fine thread configuration ensures tighter sealing and vibration resistance compared to coarse threads, while the partial threading design concentrates thread engagement where maximum clamping force is required. With 80,000 PSI tensile strength and external hex drive, these screws withstand extreme mechanical stress while enabling efficient installation in confined spaces common to equipment manufacturing, structural assemblies, and heavy machinery maintenance.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 2A thread fit tolerance per UNF standards, ensuring interchangeability with matching components. The 4 1/2" length with 1 1/8" minimum thread length provides optimal fastening capability. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and material transparency for industrial procurement requirements.
