Product Details
popular hexagon socket countersunk screws are an excellent choice when you need a fastener to sit flush or below the surface of your material.
These metric thread countersunk screws are produced in 10.9 grade steel. The finish of these fasteners is bright zinc-plated which ensures an attractive, quality appearance and finish wherever they are used. They are ideal for light fastening applications in machine tooling, security guarding, panel building and for general fastening.
These screws can be tightened or undone 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

Various thread sizes available, including M3, M4, M5, M6, M8, M10, M12 and M16
Manufactured from Bright Zinc Plated Steel (BZP)
Used in applications where a wider head and lower profile is required
Also used in many internal joinery applications
Have the marking on the head
More resilient than 8.8 grade
Nominal strength of 1040 N/mm²
Yield strength of 940 N/mm²
Typical Applications include:
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
Electronic applications
Automotive industry
Medical applications
Facilities and maintenance applications
FAQs
What is a socket screw?
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.
What is BZP?
Meaning bright zinc plating, a shiny coating is applied to the steel, this process prevents corrosion and rusting. If the application is situated within a harsh environment, BZP will provide much-needed longevity and reliability. Although it may not be as effective as stainless steel, the added benefit would be the price. As stainless steel is completely rustproof, but expensive, BZP Steel offers a great solution and is massively cost-effective.
