Professional Applications & Engineering Value
Engineered for demanding environments, these brass socket head cap screws combine material excellence with precision manufacturing. The 4-40 UNC Class 3A thread with coarse pitch ensures quick assembly and reliable performance in high-vibration settings, from machinery to electronic enclosures. Brass provides inherent corrosion resistance, eliminating galvanic issues when mating with dissimilar metals. The hex drive design allows for high-torque installation in confined spaces, while the fully threaded body maximizes load-bearing capacity. Ideal for industrial applications requiring non-magnetic, non-sparking properties, these screws deliver consistent performance in plumbing, electrical, and precision equipment assemblies.
Specification Summary & Compliance
This fastener features a 4-40 UNC Class 3A thread with right-hand direction and coarse spacing, manufactured to precise dimensional standards. The 1/4" length and fully threaded design ensure uniform engagement. It complies with REACH (EC 1907/2006) regulations, confirming its suitability for industrial use without hazardous substances. Mechanical properties include 50,000 psi tensile strength and Rockwell B55 hardness, guaranteeing reliable performance in technical applications.
