Woodscrews are available in a range of materials such as carbon steel, hardened steel, zinc, stainless steel and solid brass. Brass is usually chosen for its appearance when combined with brass ironmongery such as hinges and door handles. Stainless steel is ideal for areas exposed to moisture, and carbon and hardened steel can be fitted without needing pre-drilled holes. In addition, all wood screw materials have high levels of corrosion resistance. They are available in gauge sizes ranging from 3 to 8mm and lengths from 12 to 300mm.
Masonry screws are available in zinc, carbon steel, hardened steel, and high tensile steel. They have an anti-corrosive coating and are tarnish-resistant, making them suitable for outdoor use. They’re available in gauge sizes ranging from 3 to 10mm and lengths ranging from 16 to 200mm. Low Cost - Grub screws are generally less expensive than other types of fasteners, such as bolts or nuts. This can make them a good choice for applications where cost is a consideration.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 Cone point grub screws- These grub screws have a pointed end that is shaped like a cone. The cone-shaped point creates a deeper and more secure grip than a cup point, which makes them ideal for use in applications where the object being secured is subject to high levels of vibration or movement. Cone point grub screws are commonly used in applications such as automotive engines, aircraft, and heavy machinery.
For longer life, set screws are usually made of alloy steel and case hardened. Hardened set screws often leave a plastic deformation, in the form of a circular or semicircular mark, in the shaft that the screw sets against. This has both pros and cons. On the pro side, such deformation increases the holding power (torque resistance) of the joint, as the screw is essentially "making its own detent" on a small but effective scale. On the con side, if one is aiming to have a blemish-free cosmetic finish on the part being set against, one must take actions to prevent the circular marks. In most set screw applications, this consideration is irrelevant. Another con is that this plastic deformation can cause corresponding high points in the shaft surrounding the circular mark. This can result in difficulties during dis-assembly if a bearing or other tightly toleranced part needs to slide past this area. Use of a flat mitigates this problem. 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 Grub screws also have some disadvantages that should be considered when choosing them for a particular application. Here are some of the main disadvantages: Flat point grub screws - These grub screws have a flat end that provides a larger surface area for gripping the object being secured. Flat point grub screws are ideal for use in applications where a strong grip is required but surface damage must be minimized, such as in delicate machinery or equipment. If you are joining sheet metal to steel, choose self-drilling screws. But if you are joining sheet metal to wood, use timber roofing screws with a sharp point.

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. 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’. 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

Damage to the Shaft - Grub screws may damage the shaft if they are overtightened. This can cause the shaft to become warped or bent, which can affect the performance of the machinery or equipment. Stainless Steel, stainless steel ss 304/ SS316 A2/A4, SS201, SS303, SS304, SS316, SS316L, SS904L, A2-70, A4-80 Because they’re often chosen to work in tight or confined spaces, or as part of more intricate assemblies, it’s common to find grub screws available in a wide range of very small sizes. These can start from as little as a couple of millimetres in standard hardware configurations, but anything under about 4mm would typically be considered a ‘small’ grub or set screw. Above this, they can come in just as wide a range of sizes as most other screw types. Timber screws are specially designed for use on timber. They have an aggressive, coarse thread that grips wood securely into place. They come in various gauges, head and drive types, and sizes, meaning there is a choice of screw for any task.
When choosing masonry screws, consider the load it will bear, as different types are suitable for medium or heavy-duty loads.Before buying screws, consider the type of project you need them for. Although some are designed for multipurpose use, others are more specialised and are designed for specific applications. Using the right type for the job will ensure they can take the load and stay securely in place. When buying grub screws or set screws from most manufacturers and suppliers to the market, you'll usually find up to six different variants of grub screw shapes on offer. These include: 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. The flat point tip type is the simplest and least expensive type available and is the one that is most commonly use on model cars. For general use it is fine, but the bottom threads can deform when the grub screw is tightened which can make disassembly difficult.
