Professional Applications & Engineering Value
These 6-32 UNC zinc-plated steel screws deliver exceptional engineering value through their specialized rounded fillister head design and coarse thread configuration. The high-profile head provides superior clearance for assembly tools while the slotted drive style ensures compatibility with standard screwdrivers. Manufactured from zinc-plated steel with Rockwell B69 hardness, these fasteners resist corrosion while maintaining optimal strength-to-weight ratio. The fully threaded design and Class 2A thread fit guarantee consistent clamping force across industrial equipment, electronic enclosures, and machinery assemblies where vibration resistance and reliable fastening are critical. These characteristics make them ideal for OEM manufacturing, maintenance operations, and precision assembly applications requiring ASME B18.6.3 compliant components.
Specification Summary & Compliance
These rounded head screws feature precise 6-32 UNC coarse threads with Class 2A tolerance for reliable fitment. The 3/8" length and fully threaded construction ensure consistent performance. Manufacturing complies with ASME B18.6.3 standards for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, making them suitable for regulated industries and international markets.
