Professional Applications & Engineering Value
These brass rounded head screws deliver critical performance advantages in applications where corrosion resistance and electrical conductivity are paramount. The UNC coarse threading combined with Class 3A thread fit provides superior engagement in soft materials and prevents cross-threading during assembly. The hex drive design ensures reliable torque application without cam-out, making them ideal for electrical enclosures, marine equipment, and plumbing systems where repeated maintenance access is required. The fully threaded configuration offers maximum grip length, while the rounded button head provides a finished appearance with reduced snagging hazards in exposed applications.
Specification Summary & Compliance
This 1/4"-20 x 1-1/2" brass screw features precision UNC coarse threads with Class 3A fit for exacting dimensional accuracy. Manufactured to meet RoHS 3 (2015/863/EU) compliance with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) standards. The fastener delivers 50,000 psi tensile strength and Rockwell B55 hardness, ensuring reliable performance in industrial applications requiring corrosion-resistant brass fasteners with consistent mechanical properties.
