Professional Applications & Engineering Value

Engineered for industrial fastening challenges, these 1/4"-20 Torx Plus tapping screws deliver exceptional value in aluminum, brass, and copper applications. The zinc-plated steel construction provides reliable corrosion protection while the Tri-Lobe shank design ensures superior thread-forming action that eliminates the need for separate tapping operations. This combination significantly reduces assembly time and labor costs in manufacturing processes. The Torx Plus IP30 drive system offers higher torque transmission compared to conventional drives, minimizing fastener damage and improving installation reliability. With UNC coarse threading and full threading along the 1" length, these screws provide maximum engagement and pull-out resistance in soft materials, making them ideal for electrical enclosures, HVAC systems, and metal fabrication where vibration resistance and long-term performance are critical.
