Nut drivers

Socket screwdrivers are required for installation and dismantling of threaded fasteners with facets. One end of the blade of this hand tool is fitted with a drive socket. It tightly fits the fastener element during operation, does not slip off and damage it.

Types of socket screwdrivers

By the design of the working part:

• Single-piece. These screwdrivers are reliable; they are usually inexpensive, sold both individually and in kits.
• Two-piece, with replaceable drive sockets. They are versatile, are of high performance, but are sold at a higher price. They are often fitted with a ratchet mechanism.

When ordering online, consider the type of the blade:

• Rigid. Can withstand significant loads.
• Flexible. Such tools are suitable, for example, for installation of hardly reachable clamps.
• Telescopic. These screwdrivers are suitable for limited spaces, but cannot withstand an excessive effort.

In addition to straight tools, there are tools with a T-shaped handle. They perfectly transfer the torque, but, due to the design, do not allow reaching deep-seated fasteners.

Manufacturers' catalogues include products with drive sockets of the following types:

• Standard six- or twelve-pointed. They are intended for operations with components that have a corresponding shape.
• E (TORX). They allow working with components that have facets in the shape of a six-pointed star.
• Universal (SuperTech). They are suitable for installation of all types of elements. They do not always ensure snug fit of the working part.
• SL (SuperLock). They are required for removing damaged components. They have a large area of gripping a fastener.

Advice on using socket screwdrivers

1. The tools should be used strictly in accordance with the manufacturer's instructions, and positioned perpendicular to the fastener.
2. The shape and the size of the working part should fit the fastener. This will prevent facets deformation.
3. If long work is ahead, it is better to use a ratchet screwdriver. This will reduce the load on your hands.
4. There is no need to apply excessive force during work. If a fastener cannot be unscrewed, use a more powerful impact tool.
