Professional Applications & Engineering Value

Engineered for industrial assembly and precision equipment, these brass rounded head screws solve critical challenges in corrosive environments where steel fasteners would fail. The UNC coarse thread with Class 3A fit provides exceptional vibration resistance in machinery, electrical enclosures, and marine applications. The button head profile offers a low-profile finish while the hex drive ensures secure installation without stripping. Perfect for plumbing systems, electronic housings, and outdoor equipment, these fasteners maintain integrity in moisture-rich conditions while meeting strict RoHS 3 compliance for lead-free requirements in sensitive applications.

Specification Summary & Compliance

This 1/4"-20 UNC threaded screw features precise Class 3A thread fit per ASME B1.1 standards with coarse thread spacing for optimal engagement. The fully threaded 1-1/4" length maintains consistent 0.25" thread diameter throughout. Manufacturing complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial and commercial applications worldwide.
