RS PRO Plain Stainless Steel Hex Socket Countersunk Screw, DIN 7991, M3 x 12mm

RS PRO hexagon socket countersunk screws are an excellent choice when you need a fastener to sit flush or below the surface of your material.
These popular metric thread countersunk screws are manufactured from A2 (304) stainless steel and are designed for light duty applications where space is limited. These fasteners are used where a strong, reliable joint is required. These screws have an attractive, quality appearance and finish wherever they are used and give you exceptional resistance to corrosion.
These screws fasteners can be tightened or undone using an Allen key. They can have various tip point types which include:
Cup point – concave tip, most commonly used
Flat point – used for frequent resetting or relocating, simple and cost-effective
Cone point – pointed tip, designed for a more permanent installation, highest holding capability due to the precise contact of the cone point
Half Dog point – the tip is cylindrical

Various thread sizes available, including M3, M4, M5 and M6
Good corrosion resistance
Countersunk – the head does not stick out so that nothing can hit it and interfere with the operation of the application
Also used in many internal joinery applications
Requires an Allen key

Although uses may vary, as standard, these screws are fasteners for industrial equipment or machines which requires parts to be fixed onto a surface or together. The socket will need to be the same metric thread as the screw itself. As an example, some of the types of uses would be:
Woodworking
Domestic applications
Fasteners and fixings
Machine tooling and repair
Security guarding
Panel Building
Electronic applications
Automotive industry
Medical applications
Facilities and maintenance applications

Socket screws are defined by their name. They are a type of threaded bolt which screws into the intended socket. There are various thread sizes and lengths and can be used for both industrial and personal purposes. Good quality and reliable RS PRO socket screws ensures the fixing will remain strong and stable, whatever the application.

Stainless steel is useful for more than just a visual purpose. The main highlight would be the superior corrosion resistance, stopping unwanted issues like rusting. High heat resistance is also a big benefit, due to the way stainless steel is created, it can withstand an incredible amount of heat as opposed to a screw or socket made from standard steel. The only possible issue may be cost, however, a reliable and durable material will not only increase the longevity of the application, but also the sustainability.
