Professional Applications & Engineering Value
Engineered for precision applications requiring reliable fastening under vibration and stress, these 10-32 UNF Class 3A Black-Oxide Alloy Steel rounded head screws deliver exceptional performance in machinery assembly, electronic enclosures, and automotive components. The fine thread spacing provides superior resistance to loosening in dynamic environments, while the fully threaded design ensures maximum grip length throughout the fastener. The flanged construction eliminates the need for separate washers, reducing assembly time and component count. With Rockwell C32 hardness and 120,000 psi tensile strength, these screws maintain structural integrity in high-torque applications, making them ideal for precision engineering where failure is not an option.
Specification Summary & Compliance
Manufactured to UNF thread standards with Class 3A thread fit for precision tolerance and reliable engagement. The Black-Oxide Alloy Steel construction meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements. Features include 10-32 thread size, 1" length, 0.406" flange diameter, and right-hand fine threading for consistent performance in industrial fastening applications.
