Professional Applications & Engineering Value
These 10-32 UNF rounded truss head screws are engineered to address common industrial challenges, such as vibration loosening and corrosion-induced failure. The passivated 18-8 stainless steel material provides exceptional durability in moist or chemically aggressive settings, while the fine thread spacing and Class 2A fit ensure precise, repeatable installations in machinery, electronics, and automotive assemblies. The wide truss head distributes clamping force effectively, minimizing the risk of surface damage on softer materials. With a Rockwell B70 hardness and 70,000 psi tensile strength, these fasteners deliver long-term reliability in high-stress applications, reducing maintenance costs and downtime.
Specification Summary & Compliance
This screw features a 10-32 UNF thread with Class 2A fit and fine spacing, ensuring dimensional accuracy per ASME B18.6.3 standards. It is fully threaded and measures 7/16" in length, with a head diameter of 0.448". The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety requirements for industrial use.
