Professional Applications & Engineering Value

Engineered for demanding industrial fastening applications, these brass rounded head slotted screws combine material excellence with precision manufacturing. The 1/4-20 UNC coarse thread configuration provides excellent pull-out resistance in softer materials while the wide rounded binding head distributes clamping force evenly, preventing surface damage and maintaining seal integrity. The fully threaded design ensures maximum thread engagement throughout the fastener length, critical for electrical enclosures, instrumentation panels, and marine components where vibration resistance and corrosion protection are paramount. The Rockwell B40 hardness and 50,000 psi tensile strength deliver reliable performance in both static and dynamic loading conditions, making these screws ideal for binding head applications requiring frequent access or adjustment.
