Professional Applications & Engineering Value
This 4-40 UNC brass socket head cap screw is engineered to address common industrial challenges like corrosion and mechanical stress. The coarse thread spacing and Class 3A fit provide quick assembly and high vibration resistance, making it suitable for machinery, electronics, and automotive components. Made from brass, it naturally resists rust and galvanic corrosion, extending service life in humid or chemical-exposed settings. The hex drive design ensures torque efficiency without stripping, while the fully threaded body allows for uniform clamping force. Ideal for applications requiring 50,000 psi tensile strength and regulatory compliance, this screw delivers reliability in precision engineering and industrial fasteners.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a Class 3A fit for precise dimensional accuracy. It features a right-hand thread direction, coarse spacing, and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The inch system measurements guarantee consistency in global industrial applications.
