Professional Applications & Engineering Value

Engineered for industrial applications where corrosion resistance and mechanical reliability are critical, these 1/4"-20 UNC brass hex head screws solve common fastening challenges in electrical enclosures, marine equipment, and plumbing systems. The brass material naturally resists oxidation and galvanic corrosion, while the coarse UNC thread provides superior holding power in softer materials and high-vibration environments. With fully threaded design and external hex drive, they enable rapid installation and consistent clamping force, reducing assembly time and maintenance needs in industrial hex screw applications requiring ASME B18.2.1 compliance.

Specification Summary & Compliance

This 1/4"-20 UNC brass hex head screw features precise Class 2A thread fit with coarse thread spacing, manufactured to ASME B18.2.1 specifications for dimensional accuracy. The screw meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety and regulatory adherence for global industrial use.
