Product Information

Whether you’re an amateur or a professional watchmaker, good screwdrivers are one of the most important tools in your arsenal. Investing in a quality set of screwdrivers will pay off. From getting into your watch to adjusting the delicate movement within, these handy tools will be one of your most used. Sometimes referred to as the star drive due to its rounded 6-point star shape, the Torx drive is designed to function at higher torques and have a longer lifespan than other popular screwdriver types.

If you’ve ever been to a hardware store, you’ve probably seen hundreds of screwdrivers in a variety of designs, sizes, and other characteristics. Actually, the type of screwdriver you use depends entirely on the type of recess or screw drive you use. Much like Phillips screwdrivers, Robertson drives use a numbering system. What sets these apart, however, is that all sizes are also color-coded for easy reference.

Larger standard screwdrivers are usually fine for just tossing into a drawer or toolbox, but precision drivers will need a bit more TLC to prevent them from getting damaged, or lost among your other tools. Unless you already have a dedicated area for precision screwdrivers, I would recommend choosing an option that comes with a storage box, or even better, has a handle that can store the bits inside. Now that the original patents and licensing restrictions have begun to expire, Robertson screws are gaining in popularity worldwide. 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.

This screw drive is often referred to as an improved version of the Phillips drive. Instead of the Phillips’ pointed tip, tapered flanks, and rounded corners, a Pozidriv has a blunt tip, parallel flanks, and an additional small rib between each slot. This allows for increased grip between the bit and fastener.

A huge selection is available for a wide range of applications. They can be classified by the type of material they’re made from, such as brass, stainless steel, carbon steel, etc., their size (diameter and length) and the different screw head types, drive types and thread types. According to needs, there are light-duty screwdrivers and heavy-duty screwdrivers. They have a flat tip. Although it can be powered or manually operated, the ‘cam-out effect’ of the slotted head makes power operation less common.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 Screwdriver 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. Torx drives use a numbering system based upon the distance between two opposing points. Unlike other driver measuring systems, the same numbers on a Torx screwdriver apply to both SAE and metric scales.

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. Point: the end of the screw that’s first driven into the material when a rotational force is applied. Commonly referred to as a slotted screwdriver, these have the wedge-shaped blade that any child immediately recognizes. You can often use a slotted screwdriver to work heads with a slightly bigger slot or even Phillips (or other cruciform style) heads in a pinch. 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.One of the greatest tool inventions ever made is the screwdriver. Screwdrivers were reportedly created in the 15th century, and as we moved into the 21st century, you could find them in almost every toolbox. When 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.

You can identify the size required for a random screw by measuring the width of the slot and comparing it to a Torx sizing chart. Torx Sizes Chart Torx Size When choosing the thread, consider the density of the wood. It’s best to use fine threads for hardwoods and coarse threads for softwoods.

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.
