Professional Applications & Engineering Value
These 1-72 UNF fine thread pan 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 electronics, aerospace components, and medical devices where environmental exposure is a concern. The fine thread configuration with Class 2A fit ensures superior vibration resistance and precise torque control in thin-section materials. The fully threaded design maximizes engagement depth while the pan head profile with Phillips No. 0 drive offers reliable installation without head stripping. These fasteners solve common industrial challenges including material compatibility issues, assembly consistency requirements, and long-term reliability demands in critical mechanical systems.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit for precise dimensional accuracy. The UNF fine thread (1-72) configuration ensures optimal performance in applications requiring fine adjustment capabilities. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The passivated surface treatment enhances corrosion protection while maintaining the material's inherent strength characteristics of 70,000 psi tensile strength and Rockwell B70 hardness.
