M2-0.4 DIN 965 A4 Phillips Drive Countersunk Head Stainless Steel 316 Machine Screw

Description

M2-0.4 DIN 965 A4 machine screw has a uniform 2mm diameter the entire length of the thread as opposed to tapered screws that have a pointed tip. They are used to fasten machine components, appliances and more. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. A screw thread is the essential feature of the screw as a simple machine and also as a fastener. Our company also provides custom-made fasteners & other precision components.

Countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material (by comparison, a counterbore makes a flat-bottomed hole that might be used with a socket-head capscrew). A countersink may also be used to remove the burr left from a drilling or tapping operation thereby improving the finish of the product and removing any hazardous sharp edges.

M2-0.4 DIN 965 A4 stainless steel screws are highly durable and corrosion-resistant, ideal for demanding environments. The addition of molybdenum offers superior resistance to corrosion, especially in saltwater, acidic, and chloride-rich conditions, making them ideal for marine and industrial applications.

These screws also withstand extreme high and low temperatures while retaining their strength, making them suitable for heat exchangers and refrigeration. They are generally non-magnetic, reducing interference in electronics and medical equipment. Additionally, their smooth, easy-to-clean surface is perfect for medical, food processing, and pharmaceutical settings, where hygiene is essential.

Stainless steel 316 screws combine strength, durability, and aesthetic appeal, making them a reliable choice for high-stress, outdoor, and visible applications.

Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.
