M3 x 20mm Phillips Flat Head Machine Screw Steel Black Oxide

MFPM320BX is a M3 Flat Head head Phillips drive screw made of Black Oxide Steel, manufactured by Superneer Limited. It has a length of 20 mm and is commonly used in electronics, watches, precision instruments, and 3D printers.

The MFPM320BX screw features thread size M3, length of 20 mm, head type Flat Head (head diameter 6±0.25 mm), drive type Phillips (drive size Ph No.2), and is made of Black Oxide Steel.

The MFPM320BX screw is made of Black Oxide Steel. Superneer provides material test reports (MTR) and RoHS compliance certificates for all products. Black Oxide Steel offers excellent corrosion resistance and mechanical strength.

The MFPM320BX screw has a M3 thread. This is a metric thread with M3 specification, commonly used in international applications following ISO standards.

MFPM320BX 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 MFPM320BX is 10,000 pieces. The unit price is $0.020 USD for MOQ quantity. Larger quantities receive discounted pricing. Contact [email protected] for custom quotes.

The lead time for MFPM320BX 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 M3 thread is approximately equivalent to #6 (approx 6-32). When substituting metric screws with inch screws, always verify the actual diameter and pitch compatibility.

The MFPM320BX 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 MFPM320BX (M3, 20 mm), ensure your application requires this specific size.

MFPM320BX uses Black Oxide Steel finish, while alternative variants in the same thread/length specification include MFPM320S (SUS304 Stainless Steel), MFPM320N (Nickel Plated Steel). The Black Oxide Steel of MFPM320BX is specifically selected because it offers high tensile strength for mechanical and structural applications where corrosion resistance is not the primary concern, often used in machinery, automotive chassis, and load-bearing assemblies. This distinction makes MFPM320BX the preferred choice when these properties align with your application requirements.
