4 × 3/16" Truss Head Phillips Thread Forming inch Screws for Plastic SUS304 Stainless Steel Inox

PTP0403S is a 4-20 Truss Head head Phillips drive screw made of SUS304 Stainless Steel, manufactured by Superneer Limited. It has a length of 3/16 inches and is commonly used in electronics, watches, precision instruments, and 3D printers.

The PTP0403S screw features thread size 4-20, length of 3/16 inches, head type Truss Head (head diameter 0.241-0.257 inches), drive type Phillips (drive size PH No.1), and is made of SUS304 Stainless Steel.

The PTP0403S screw is made of SUS304 Stainless Steel. Superneer provides material test reports (MTR) and RoHS compliance certificates for all products. SUS304 Stainless Steel offers excellent corrosion resistance and mechanical strength.

The PTP0403S screw has a 4-20 thread. This is a UNC (Unified National Coarse) thread with 4-20 specification, widely used in North American applications.

PTP0403S Truss Head head Phillips drive screws are used in electronics assembly, PCB mounting, precision instruments, watches, 3D printers, optical devices, medical equipment, and consumer products where reliable fastening with Truss Head head aesthetics is required.

The minimum order quantity (MOQ) for PTP0403S is 10,000 pieces. The unit price is $0.022 USD for MOQ quantity. Larger quantities receive discounted pricing. Contact [email protected] for custom quotes.

The lead time for PTP0403S is 15-25 days for production. Shipping to USA takes 5-15 days via sea freight, with shipping cost starting from $50 USD. Air freight is available for urgent orders. DDP and FOB terms are both available.

The PTP0403S uses a Truss Head head type. Truss 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 PTP0403S (4-20, 3/16 inches), ensure your application requires this specific size.

PTP0403S uses SUS304 Stainless Steel finish, while alternative variants in the same thread/length specification include PTP0403Z (Blue Zinc Plated Steel), PTP0403B (Black Zinc Plated Steel), BPTP0403S (SUS304 Stainless Steel), BPTP0403Z (Blue Zinc Plated Steel), BPTP0403B (Black Zinc Plated Steel). The SUS304 Stainless Steel of PTP0403S 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 PTP0403S the preferred choice when these properties align with your application requirements.
