Product Information

The shank length will affect whether the screwdriver can fit into a deeper recess (perfect for automotive work) or if it functions best where there’s very little room for your hand. Note that the length of the handle is proportionate to the length of the shank, so short-shanked drives also have short handles.

I assume you were confused between a screwdriver and a screw drive, though? Just keep reading, and all of your confusion will be resolved. 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. Consider the material you are screwing into. Self-tapping screws are suitable for fixing sheet metal to softwood or plastic, and self-drilling screws are best for sheet metal to steel. Roofing screws are available in carbon steel and hardened steel. And, as they are most commonly used for outdoor applications, they have a coating that protects them from the elements and stops rusting. They’re available in gauge sizes ranging from 4 to 6.3mm and lengths ranging from 16 to 120mm. 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

If you plan on using your screwdriver near any kind of live electrical wiring, you’ll need to use an insulated model.

Power drills with flat or Phillip’s heads are frequently used along with multi-bit screwdrivers. 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.

Look for features such as shanks that reduce wood split, twin threads for a fast and accurate drive, and tips that don’t require pre-drilling. The Phillips head was adopted by Ford and was unfortunately spread through Europe (and the rest of the world) via WWII equipment. I have never used a Robertson but I have read much about it and I have lamented for years about the awful slut, I mean slot head screw and the the commonly “cammed out” Phillips. Oh for a world full of Robertson heads and the drivers of course. The carpenter screwdriver is made of a round rod and a flat tip. Its handle is flat on two sides (as shown in the figure). This enables the worker to exert full force or screwdriver. #15 Bolster ScrewdriverWhen choosing the thread, consider the density of the timber. It’s best to use fine threads for hard timber and coarse threads for soft timber.
