Professional Applications & Engineering Value
These 3-48 UNC zinc-plated steel rounded head screws are engineered to address common industrial fastening challenges, such as vibration loosening and environmental degradation. The zinc plating provides a protective barrier against moisture and chemicals, significantly enhancing corrosion resistance in machinery, electrical enclosures, and automotive components. With a Rockwell B70 hardness and fully threaded UNC coarse profile, they deliver high tensile strength and reliable clamping force, reducing maintenance needs in high-stress assemblies. The No. 1 Phillips drive and pan head style facilitate quick installation with standard tools, improving assembly line efficiency while meeting ASME B18.6.3 specifications for consistent quality.
Specification Summary & Compliance
This screw features a Class 2A thread fit for standard tolerance applications, with UNC coarse threads (3-48 size) and dimensions including 3/16" length and 0.193" head diameter. Manufacturing adheres to ASME B18.6.3 standards, ensuring precise thread form and head geometry. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for safe use in global markets.
