Professional Applications & Engineering Value
These 3-48 UNC zinc-plated steel rounded head screws are engineered to address critical fastening challenges in demanding industrial settings. The zinc-plated steel material provides essential corrosion protection for applications exposed to moisture or chemicals, while the Rockwell B70 hardness maintains structural integrity under repeated stress. The coarse UNC threading with Class 2A fit ensures quick, secure installation in various materials without compromising joint strength. The pan head profile with Phillips drive offers a low-profile solution for assemblies where clearance is limited, making these fully threaded screws ideal for electronics enclosures, machinery components, and automotive applications requiring reliable, vibration-resistant fastening solutions.
Specification Summary & Compliance
These rounded head screws feature precise Class 2A thread fit per UNC standards with 3-48 thread size and 7/8" length. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and performance. The products are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety regulations for industrial use.
