RS PRO A2 Stainless Steel Hexagon Socket Head Screws, Metric Thread

The RS PRO hexagon head socket cap screws have a narrow head and are perfect for use in hard to reach areas. The fasteners areuseful in machine repair and maintenance and in many sectors.
As these socket cap screws are made from A2 (304) stainless stee, they are ideal for use in the food and beverage industry. A2 stainless steel provides good corrosion resistance and is more affordable than A4 (316) stainless steel.

The socket screws can be tightened or loosened using an Allen key or a hex 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

Features and Benefits

• Various thread sizes available, including M3, M4, M5, M6, M8 and M10 • Manufactured from A2 stainless steel
• Can be used instead of hex bolt when there is less clearance
• Socket Head Cap Screw – strongest of all head styles
• Head height is equal to shank diameter


Although uses may vary, as standard, these screws are fasteners for industrial equipment or machines which require 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:

• Fasteners and fixings
• Machine tooling and repair
• Security guarding
• Electronic applications
• Automotive industry
• Domestic applications
• Medical applications
• Facilities and maintenance applications

What is a socket screw?

Socket screws are a type of threaded bolt which screws into an appropriate socket, and are used to fasten various materials together. They are designed to be turned by hex keys or similar tools. Good quality and reliable RS PRO socket screws ensures the fixing will remain strong and stable in all kinds of applications, including industrial.

What are the benefits of stainless steel?

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.
