Professional Applications & Engineering Value

These zinc-plated steel rounded head screws with 2-56 UNC coarse threading address critical fastening challenges in industrial assembly lines. The combination of Rockwell B70 hardness and 60,000 psi tensile strength prevents thread stripping and head deformation during high-torque installations. The pan head profile with Phillips No. 1 drive maintains flush mounting while providing sufficient driving torque transfer. Fully threaded construction ensures consistent clamping force across the entire 3/4" length, making these ASME B18.6.3 compliant screws ideal for electronics enclosures, machinery guards, and automotive components where vibration resistance and corrosion protection are paramount.

Specification Summary & Compliance

Manufactured to Class 2A thread fit tolerances with UNC coarse threads meeting ASME B18.6.3 specifications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features right-hand threading with standard rounded pan head profile and fully threaded design for consistent mechanical performance.
