- Full threading along the 3/16" length ensures maximum grip and uniform stress distribution
- Compliance with ASME B18.6.3 and environmental standards guarantees consistent quality and regulatory acceptance
Professional Applications & Engineering Value
This 1-72 UNF fine thread rounded head slotted screw delivers critical performance in precision assemblies where space constraints and material compatibility are paramount. The combination of 18-8 stainless steel construction and passivated surface treatment provides exceptional resistance to oxidation and chemical exposure, making it ideal for electronics enclosures, medical devices, and marine components. The fine thread configuration offers superior holding power in thin materials and soft metals, while the Class 2A thread fit ensures consistent engagement without cross-threading risks. Engineers specify these fully threaded screws for applications requiring repeated disassembly, as the Rockwell B100 hardness maintains thread form integrity through multiple cycles.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread tolerances for precision fit. The 1-72 UNF fine thread maintains consistent pitch accuracy across the full 3/16" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries. Right-hand thread direction with standard rounded head profile conforms to industrial fastening standards.
