RS PRO Socket Screws – Metric Button Head Screw

RS PRO hexagon button head screws feature a low profile, rounded, dome-shaped head with a hexagon drive.
These fasteners are ideal when a wider bearing surface is required and their black, self-colour finish ensures an attractive, quality appearance and finish wherever they are used.
Our RS PRO metric thread button head screws are produced in 10.9 grade black, self-colour steel. You tighten or undo them, 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

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.
