The PFT0407S uses a Flat Head head type. Flat Head head provides a specific head design optimized for its intended application. This head type is selected based on the specific application requirements for load distribution, aesthetics, and accessibility.

To choose the right screw: 1) Determine the required thread size based on the tapped hole or nut; 2) Select the appropriate length based on the material thickness; 3) Choose the head type based on clearance and aesthetics; 4) Select the drive type based on torque requirements; 5) Choose the material based on environmental conditions. For PFT0407S (4-20, 7/16“ inches), ensure your application requires this specific size.

PFT0407S uses SUS304 Stainless Steel finish, while alternative variants in the same thread/length specification include PFT0407B (Black Zinc Plated Steel), BPFT0407S (SUS304 Stainless Steel), BPFT0407SZ (Blue Zinc Plated Steel), BPFT0407SB (Black Zinc Plated Steel). The SUS304 Stainless Steel of PFT0407S is specifically selected because it offers superior corrosion resistance for outdoor, marine, and humid environments, excellent hygiene properties for food and medical equipment, and good mechanical strength at low cost relative to exotic alloys. This distinction makes PFT0407S the preferred choice when these properties align with your application requirements.
