Professional Applications & Engineering Value
These 10-32 UNF truss head screws are engineered to address critical challenges in industrial assembly and maintenance. The passivated 18-8 stainless steel provides exceptional resistance to oxidation and chemical exposure, making them suitable for applications in manufacturing, electronics, and outdoor equipment where environmental durability is paramount. The wide truss head profile distributes clamping force over a larger surface area, preventing damage to softer materials and reducing the risk of loosening under vibration. Combined with the Phillips #2 drive and fine UNF threading, these screws deliver reliable, repeatable fastening in precision assemblies, from machinery frames to enclosures requiring consistent torque and long-term integrity.
Specification Summary & Compliance
This fastener features a Class 2A thread fit for consistent assembly and meets ASME B18.6.3 dimensional specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are adhered to. The screw maintains a Rockwell B70 hardness and 70,000 PSI tensile strength, confirming its reliability in demanding mechanical applications.
