Professional Applications & Engineering Value
This alloy steel shoulder screw delivers critical engineering solutions where precision alignment and high strength are paramount. The 10-32 UNF fine thread with Class 3A fit provides superior vibration resistance in rotating machinery, while the black oxide finish protects against corrosion in industrial environments. The precisely machined 1/4" shoulder diameter ensures accurate component positioning in assemblies, eliminating misalignment issues in precision equipment, automotive systems, and manufacturing jigs. With 140,000 psi tensile strength and Rockwell C32 hardness, this fastener maintains structural integrity under dynamic loads, making it ideal for applications requiring repeated disassembly and reassembly without performance degradation.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit and UNF thread specifications. The shoulder diameter maintains tight tolerance of -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005". Compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as alloying element in steel and REACH (EC 1907/2006) standards, ensuring environmental regulatory adherence for industrial applications worldwide.
