These screws can be made from materials such as steel, stainless steel, nylon, brass and ceramic and are available in a wide range of very small sizes. Types of Grub Screw Westfield Fasteners Limited is a company registered in England and Wales with company number 07215583. Contains the most popular sizes of flat and cone-point grub screws. For use in securing sliding or moving components. Supplied in a handy carry case with separate inner compartments. If it won’t budge and needs to be drilled out, start by taking an awl or centre punch and using it with a hammer to make a small indentation in the visible end of the grub screw - this will help reduce the risk of the drill bit from slipping or wandering while you drill through the metal

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 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. cheaper options with no signature required. The no signature required options are at the customer’s risk once the goods leave our store. 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’.

You can only compare up to four products at a time.

A grub screw, also known as a set screw is used for securing sliding or moving components in place. Grubs screws have threaded inserts instead of tapering screw grooves. The screw is passed through a threaded hole in the outer object and then tightened against the inner object to prevent it from moving relative to the outer object. Grub screws are commonly used to secure a pulley or a gear to a shaft or for attaching a handle or cam to a spindle. You can learn more in our comprehensive grub screws guide and our complete set screws guide. 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. knurled point grub screws, which do much the same as cup point versions but also feature a serrated end for additional friction/grip You can apply a penetrating lubricant to help reduce and remove any rust or corrosion present around the threads of the grub screw prior to starting

low priced hobby bearings, screws, brass and aluminium rod and tubing, shim - see the full listing in the Besides aesthetics, another advantage of using grub screws (with no leading or trailing edge exposed at the head end) is that they can often offer better resistance to weathering and corrosion as a result. They can also be driven with considerably more torque force than traditional screws, as the uniform diameter right the way along the full length of the grub screw shaft means that they don’t begin to split the hole apart as they go in further. Instead, the the surrounding material into which the set or grub screw is driven will work to reinforce the fastening as it goes in.

However, the basic steps to removing a grub screw will be largely similar to those required for removing any other type of threaded fastener: Each screw size is described using two numbers – the ‘M’ number and a number indicating the length of the shank, in mm, so M2 screw dimensions of M2 x8, are 8mm long, measured under the screw head.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.

M2 screws are available in a wide range of materials including steel, stainless steel, brass, nylon, aluminium and titanium as well as exotic materials including Duplex, Super Duplex and Inconel.Hobby and Engineering Supplies is part of MBA Group offering a select range from the MBA Group catalogue. The ‘M’ here basically signifies metric units - an M8 x 12mm grub screw will be 8mm wide at the major (outer) diameter of the thread, and 12mm long. Similarly, an M5 x 150mm set screw will be 5mm in diameter across its threaded section, and 150mm long from head to end. M2 screws are typically used in the manufacture of small items of electrical equipment, laptops, cameras and mobile phones. The “M” designation for metric screws indicates the outer diameter of the screw in millimetres, so for an M2 screw, the outer diameter is 2mm. However, in practice the actual diameter might be between 1.9mm-2mm due to manufacturing tolerances. When buying grub screws or set screws from most manufacturers and suppliers to the UK market, you'll usually find up to six different variants of grub screw shapes on offer. These include: 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.
