Professional Applications & Engineering Value

This 1/4"-20 UNC brass hex head screw delivers exceptional engineering value in applications where corrosion resistance, electrical conductivity, and mechanical reliability are critical. The brass construction prevents rust and galvanic corrosion in marine, plumbing, and electrical enclosures, while the Rockwell B55 hardness and 50,000 psi tensile strength ensure durable performance under mechanical stress. The partially threaded design with 3/4" minimum thread length provides optimal clamping force distribution, reducing the risk of material damage in softer substrates. The coarse UNC threading enables quick assembly in production environments, and the external hex drive accommodates high-torque installation. Ideal for industrial fastening in manufacturing equipment, electrical panels, and marine hardware where consistent performance and regulatory compliance are mandatory.

Specification Summary & Compliance

This screw maintains Class 2A thread fit tolerance for reliable mating with nuts and threaded components, manufactured to ASME B18.2.1 dimensional standards. The 1/4"-20 UNC coarse thread specification ensures interchangeability with standard components. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial applications.
