6G x 1 (25mm) 304SS Sq #1 Pan S/Tap Screw x 1000 - Stainless Steel (Hware)

The 6G x 1" (25mm) 304SS Square #1 Pan Head Self-Tapping Screw is a commercial-grade trade fastener supplied as a bulk trade box containing 1,000 pieces. Each screw measures 6 Gauge (approximately 3.5mm shank diameter) by 1 inch (25mm) in total operational length, measured from the flat underside of the head to the tip of the screw. The screws feature a #1 Square Drive (Robertson) recess, offering positive driver bit engagement, high torque transfer, and reduced cam-out or head stripping during high-speed installation. The pan head style provides a flat underside with a broad surface area, distributing clamping pressure evenly over architectural framing, hardware brackets, or sheet metal without warping the material. Forged from premium Grade 304 (A2-70) Stainless Steel, the screws offer outstanding strength and excellent resistance to rust and atmospheric corrosion, making them well suited to long-term outdoor and high-humidity environments. The self-tapping thread point automatically cuts its own mating threads when driven into pre-drilled pilot holes in aluminium profiles, thin steel sheet panels, or hard plastics. These screws are commonly used to mount perimeter architectural hardware accessories such as security door locks, door stops, or commercial window seals, to secure light-gauge metal panel sheets and trims within shopfront framing systems like Alspec commercial suites, and for general construction, joinery fabrication, and outdoor cabinetry work.
