Professional Applications & Engineering Value
These 10-32 UNF rounded truss head screws deliver critical engineering advantages in precision assembly applications. The passivated 18-8 stainless steel construction provides exceptional corrosion resistance, making them ideal for electrical enclosures, marine equipment, and food processing machinery where moisture exposure is common. The wide truss head design distributes clamping force over a larger surface area, preventing damage to softer materials while maintaining secure fastening. With fine UNF threading and Class 2A thread fit, these screws ensure vibration-resistant connections in automotive components, industrial controls, and precision instruments. The combination of 70,000 psi tensile strength and Rockwell B70 hardness provides reliable performance in high-stress applications while maintaining corrosion protection throughout the fastener's service life.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 standards with Class 2A thread fit precision for consistent performance. Features 10-32 UNF fine threads with right-hand direction and full threading along the 1-1/8" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The passivated surface treatment on 18-8 stainless steel provides enhanced corrosion resistance while maintaining the material's inherent strength characteristics.
