M4 x 40mm Phillips Flat Head Machine Screw SUS304 Stainless Steel

MFPM440S is a M4 Flat Head head Phillips drive screw made of SUS304 Stainless Steel, manufactured by Superneer Limited. It has a length of 40 mm and is commonly used in electronics, watches, precision instruments, and 3D printers.

The MFPM440S screw features thread size M4, length of 40 mm, head type Flat Head (head diameter 7.8±0.25 mm), drive type Phillips (drive size Ph No.2), and is made of SUS304 Stainless Steel.

The MFPM440S 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 MFPM440S screw has a M4 thread. This is a metric thread with M4 specification, commonly used in international applications following ISO standards.

MFPM440S Flat 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 Flat Head head aesthetics is required.

The minimum order quantity (MOQ) for MFPM440S is 10,000 pieces. The unit price is $0.051 USD for MOQ quantity. Larger quantities receive discounted pricing. Contact [email protected] for custom quotes.

The lead time for MFPM440S 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 M4 thread is approximately equivalent to #8 (approx 8-32). When substituting metric screws with inch screws, always verify the actual diameter and pitch compatibility.

The MFPM440S 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 MFPM440S (M4, 40 mm), ensure your application requires this specific size.

MFPM440S uses SUS304 Stainless Steel finish, while alternative variants in the same thread/length specification include MFPM440N (Nickel Plated Steel), MFPM440BX (Black Oxide Steel). The SUS304 Stainless Steel of MFPM440S 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 MFPM440S the preferred choice when these properties align with your application requirements.
