Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
- Effortless installation and removal with Phillips No. 1 drive design, reducing assembly time and tool wear
- Reliable thread engagement through Class 2A coarse UNC threads, minimizing cross-threading risks in high-vibration applications
- Enhanced mechanical strength from Rockwell B70 hardness, providing consistent performance under load
- Maximum holding power with fully threaded 1/2" length design, ensuring secure fastening across material thicknesses
- Broad compatibility with standard 0.193" pan head profile, fitting common counterbores and assembly requirements
- Regulatory peace of mind meeting ASME B18.6.3, RoHS 3 and REACH compliance for global industrial use
Professional Applications & Engineering Value
These 3-48 UNC zinc-plated steel rounded head screws deliver critical performance where corrosion resistance and mechanical reliability intersect. The coarse thread design combined with Class 2A thread fit ensures rapid assembly in production environments while maintaining vibration resistance in machinery, electronics, and automotive components. The Rockwell B70 hardness provides optimal durability against stripping and deformation, while the fully threaded configuration maximizes pull-out strength in various material thicknesses. The zinc plating creates a sacrificial barrier against oxidation, making these pan head screws ideal for applications exposed to moisture or chemical agents without compromising the Phillips No. 1 drive functionality during repeated maintenance cycles.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent engagement. Features UNC coarse threads (3-48) with right-hand orientation and fully threaded 1/2" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions.
