Product Information

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

Hobby and Engineering Supplies is part of MBA Group offering a select range from the MBA Group catalogue. 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. 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’. cheaper options with no signature required. The no signature required options are at the customer’s risk once the goods leave our store.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.

Westfield Fasteners Limited is a company registered in England and Wales with company number 07215583. knurled point grub screws, which do much the same as cup point versions but also feature a serrated end for additional friction/grip As stated in the section above, the most common uses for grub screws are to join or clamp one object or component tightly against another, but in specific scenarios where the use of a more traditional nut and bolt combination isn’t ideal for various reasons. 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.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. Regardless of the exact type or shape of grub screws and set screws you’re looking to buy, you’ll generally find them sold to a range of sizing specifications, including grub screw sets defined in both imperial (inches and fractions of inches) and metric (millimetres) units of measurement.
