About this deal

Hex keys are named because they have a smooth hexagonal shank and no head. More commonly referred to as Allen wrenches, these screwdrivers sometimes come in an L-shaped shank with no handle, as multiple retractable sizes with a centrah handle (ala Swiss army knives), or even with a ball-shaped tip.

Roofing screws are designed for attaching sheet metal to steel or wood as well as for other general exterior construction tasks. But they can also be used on internal jobs. The flanged (or washered) type of heads have a built-in washer that’s designed to reduce vibrations and stop the screws from loosening. And there are self-drilling and timber varieties available. Most screwdrivers come in sets and are universally colour-coded to designate different sized blades needed for most watch repairs and f it with hexagonal end pieces to stop them from rolling on your workbench. Another important feature of a watchmakers screwdriver is the ball bearing on the top piece of the handle which gives the screwdriver swivel action. This component is key when working on delicate parts. It helps stabilise and create a smooth rotation as you screw or unscrew to avoid any slip or slide off the screw that could lead to damage on other, more important watch parts. Grub screws: work using a pinning action that pushes two surfaces against each other, negating the need for a nut. They are often used in applications requiring a small, unobtrusive screw. This has made them quite popular in both electronics and automotive industries. They can also be used as an emergency substitute for hex drives, although there’s a higher risk of stripping the head.

Popular in both construction and electrical fields, the Robertson drive (commonly referred to as the square drive) is more common in Canada than the US due to licensing problems earlier in its history. Ratchet Screwdriver: Ratcheting screwdrivers feature an internal ball-bearing mechanism that makes turning the screw simple and repetitive. You can do this without taking out the screw’s driver head. Although most precision screwdriver sets will offer similar bit sizes, they may not always have the same bit types. If you think you may be dealing with a more obscure fastener head than just Phillips or slotted — like Y-shaped or triangle — make sure the kit you choose includes that bit. If you’re not sure what you’ll be working on, but still want to be prepared for anything, we would recommend you play it safe and go with a kit with a large number of bits. In addition to their small bits, precision screwdrivers also typically feature a spinning end cap, which makes them comfortable to control and maneuver, even one-handed.

Robertson refused to license it to Ford because he had previously license it to a business in England but they went and declared bankruptcy so they could avoid paying the license fee/royalties and then went and started a new company free from license restriction. This unfortunately make Robertson shy away from Ford because it cost him a lot of time and money to fight the English fraudsters and didn’t want to go through that again. 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.

Watchmaker Screwdrivers & Sharpening Tools

When choosing the thread, consider the density of the wood. It’s best to use fine threads for hardwoods and coarse threads for softwoods. 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. Self-tapping and drilling screws are available in steel, carbon steel, and stainless steel. Gauge sizes range from 3.5 to 6.3mm, and lengths range from 12 to 120mm.

Unlike other driver measuring systems, the same numbers on a Torx screwdriver apply to both SAE and metric scales. 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. Self-tapping screws are screws that create their own thread as they are driven into a material, ensuring a strong, tight fit. They are best used in soft materials such as softwoods and plastic. A pilot hole that’s slightly smaller in diameter needs to be pre-drilled before fitting.Tri-wing screwdrivers are costly and not easily available like other drivers. These drivers were previously manufactured for use in aerospace engineering, but now you can easily find them in home electronics. #14 Carpenter Screwdriver
