Professional Applications & Engineering Value
These 2-56 UNC thread socket head cap screws are engineered to address critical fastening challenges in precision assemblies. The 18-8 stainless steel material provides inherent resistance to rust and oxidation, making them suitable for electronics, aerospace, and marine equipment where moisture exposure is a concern. The coarse UNC threads and Class 3A fit enable quick, reliable installation with reduced risk of stripping, while the hex socket drive ensures high torque transmission without cam-out. Ideal for securing components in machinery, enclosures, and instrumentation, these screws deliver consistent clamping force and 70,000 psi tensile strength to withstand dynamic loads and vibrations in industrial settings.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications, these screws feature 2-56 UNC coarse threads with a Class 3A thread fit for precision tolerance. The partially threaded design includes a minimum thread length of 5/8" on a 7/8" overall body. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms adherence to environmental and safety standards, supporting use in regulated industries.
