6 Piece Precision Screwdriver Set, Mini Sizes, Phillips (Cross Head) with Custom Hard case. ENGINEER dm-20

Product Information

Yankee Screwdriver: Instead of using ball bearings, this screwdriver uses a spring-loaded mechanism. Instead of twisting the screw with your wrist, you place the screw head against the screw and push it to tighten.

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. The purpose of a screwdriver is to both insert and remove screws and nuts. If you want to replace a watch’s battery, you won’t use the same screwdriver you use to hang a shelf on a wall. The different functional screwdriver design types are described below. Point: the end of the screw that’s first driven into the material when a rotational force is applied.

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. Robertson Sizes Chart Color Code 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.

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.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.

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. 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.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. 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. The blade is the lower part of the shank. It is also known as a tip. This part is hardened and tempered. 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.
