Professional Applications & Engineering Value
This socket head cap screw delivers critical performance where standard fasteners fail. The 18-8 Stainless Steel composition resists oxidation and chemical exposure in manufacturing equipment, marine applications, and food processing machinery. Engineered with Class 3A thread fit and UNC coarse threads, it maintains clamping force under vibration while allowing rapid installation in structural components and heavy machinery. The 3/8" square drive and high-profile socket head withstand high torque requirements during assembly, preventing tool slippage and damage. These industrial screws solve common challenges of joint integrity, corrosion-induced failure, and maintenance downtime across multiple sectors.
Specification Summary & Compliance
This fastener meets Class 3A thread fit standards for precision and features 1/2"-13 UNC coarse threads with right-hand direction. Manufacturing adheres to inch system specifications with fully threaded 1 1/4" length. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental responsibility while maintaining mechanical properties including 70,000 psi tensile strength and Rockwell B84 hardness.
