M4 x 8mm Flat Socket Set Screws 12.9 Carbon Steel Black DIN913

HFSM408G is a M4 head Socket drive screw made of 12.9 Grade Steel, manufactured by Superneer Limited. It has a length of 8 mm and is commonly used in electronics, watches, precision instruments, and 3D printers.

The HFSM408G screw features thread size M4, length of 8 mm, head type (head diameter N/A mm), drive type Socket (drive size N/A), and is made of 12.9 Grade Steel.

The HFSM408G screw is made of 12.9 Grade Steel. Superneer provides material test reports (MTR) and RoHS compliance certificates for all products. 12.9 Grade Steel offers excellent corrosion resistance and mechanical strength.

The HFSM408G screw has a M4 thread. This is a metric thread with M4 specification, commonly used in international applications following ISO standards.

HFSM408G head Socket 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 head aesthetics is required.

The minimum order quantity (MOQ) for HFSM408G is 10,000 pieces. The unit price is $0.012 USD for MOQ quantity. Larger quantities receive discounted pricing. Contact [email protected] for custom quotes.

The lead time for HFSM408G 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 HFSM408G uses a head type. 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 HFSM408G (M4, 8 mm), ensure your application requires this specific size.

HFSM408G uses 12.9 Grade Steel finish, while alternative variants in the same thread/length specification include HFSM408S (SUS304 Stainless Steel), HFSM408B (Black Steel). The 12.9 Grade Steel of HFSM408G 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 HFSM408G the preferred choice when these properties align with your application requirements.
