M4 x 25mm Phillips Flat Head Machine Screw Steel Black Oxide

MFPM425BX is a M4 Flat Head head Phillips drive screw made of Black Oxide Steel, manufactured by Superneer Limited. It has a length of 25 mm and is commonly used in electronics, watches, precision instruments, and 3D printers.

The MFPM425BX screw features thread size M4, length of 25 mm, head type Flat Head (head diameter 7.8±0.25 mm), drive type Phillips (drive size Ph No.2), and is made of Black Oxide Steel.

The MFPM425BX 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 MFPM425BX screw has a M4 thread. This is a metric thread with M4 specification, commonly used in international applications following ISO standards.

MFPM425BX 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 MFPM425BX is 10,000 pieces. The unit price is $0.032 USD for MOQ quantity. Larger quantities receive discounted pricing. Contact [email protected] for custom quotes.

The lead time for MFPM425BX 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 MFPM425BX 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 MFPM425BX (M4, 25 mm), ensure your application requires this specific size.

MFPM425BX uses Black Oxide Steel finish, while alternative variants in the same thread/length specification include MFPM425S (SUS304 Stainless Steel), MFPM425N (Nickel Plated Steel). The Black Oxide Steel of MFPM425BX 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 MFPM425BX the preferred choice when these properties align with your application requirements.
