Professional Applications & Engineering Value
These zinc-plated steel machine screws with Phillips pan head design deliver exceptional value in industrial assembly, electrical enclosures, and machinery maintenance. The UNC coarse thread and Class 2A fit prevent cross-threading and ensure rapid installation in metal, plastic, and composite materials, reducing labor costs. With 60,000 psi tensile strength and full threading, they address common failure points in vibration-prone applications, providing reliable clamping force. The zinc plating offers sacrificial protection against rust, extending service life in humid or outdoor conditions, while the rounded pan head profile minimizes snagging and improves safety in accessible areas.
Specification Summary & Compliance
This screw features precise Class 2A thread fit per UNC standards, ensuring consistent engagement and interchangeability. Manufacturing adheres to ASME B18.6.3 specifications for dimensional accuracy, including 6-32 thread size, 1-3/8" length, and pan head geometry. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe use in global markets.
