Grub screws, also known as set screws, are a type of fixing screw that’s most often used to join one component or part securely to another. cone point tip grub screws, which are ideal for exerting additional force when joining items made from softer materials, or to fit into an existing depression in the piece being mated to cup point grub screws, which offer much the same function as cone point varieties but can be driven still further to provide even more torque and gripping force

The most obvious point of distinction between grub screws and other types of standard screws and bolts is that true grub screws tend not to feature a protruding head. Instead, they’re usually threaded right to the top, and are the same diameter all the way along their length, meaning that the grub screw can be fully driven into its hole to sit flush with (or even countersunk into, depending on the application) the workpiece. A single dab of SCREW GRAB® creates a positive grip between metal surfaces (tests have shown as high as 800%) that virtually eliminates tool wear or rounding and deforming of fasteners.

Insert the correct kind of drive for the type of grub screw in question, and make sure it is securely seated

Typical examples of uses for grub screws might include any situation where one object or component needs to clamp to another tightly via friction, but where protruding parts of the fastener would interfere with smooth functioning of the items in question. Grub screws for this purpose are especially widely used in architectural ironmongery, and are a very common feature found wherever door handles are attached to spindle shafts.RS PRO brings you this fantastic screw grab designed to help you remove or tighten stripped screws. With just a single dab of this screw grab, you create a positive grip between metal surfaces that virtually eliminates tool wear or rounding and deforming of fasteners and damaged screws. Increases the life of your tools and screws. With just a dab of screw grab you won't need a screw extractor ever again. Set screws often do feature a head - very likely a hex fitting - but without a threadless section immediately below it (again, this is different to the length of unthreaded shank you’d typically find on a standard bolt). Because they often feature no protruding screw head in the traditional sense, true grub screws tend to be driven by means of a sunken internal recess at what is still generally referred to as the ‘head end’. Nylon or nylon-tipped grub screws and set screws tend to be preferred in applications where a tight and secure friction-based fixing is required, but where it’s important for aesthetic or structural reasons not to mark or damage the mating surface.
