Professional Applications & Engineering Value
This zinc-plated steel slotted pan head screw is engineered to address critical fastening challenges in industrial settings where vibration, corrosion, and mechanical stress are common. The UNC coarse thread design provides rapid assembly and strong holding power in metal, wood, and composite substrates, reducing installation time while maintaining joint integrity. With a 60,000 PSI tensile strength and Rockwell B60 hardness, it resists stripping and deformation under heavy loads, making it ideal for machinery, structural frames, and equipment manufacturing. The rounded pan head distributes clamping force evenly and minimizes protrusion, enhancing safety and aesthetics in visible applications. Fully compliant with ASME B18.6.3 standards, it delivers consistent performance for OEM and MRO requirements.
Specification Summary & Compliance
This screw features a 3/8"-16 UNC thread with Class 2A fit for precise dimensional accuracy and coarse spacing to facilitate quick engagement. Manufactured to meet ASME B18.6.3 specifications, it ensures reliable threading and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
