1. Handle:

Every screwdriver has a handle, which serves as the user’s grip and control point. The handle is typically made of wood, plastic, or rubber, providing a comfortable and ergonomic hold.

Its design may include ridges or contours to prevent slippage during use, ensuring a firm and secure grasp.

2. Shank:

The shank, also known as the blade, is the elongated rod-like portion of the screwdriver that connects the handle to the tip. It is usually made of high-quality steel, which imparts strength, durability, and resistance to bending or breaking.

The shank’s length and diameter can vary, allowing for versatility in applications and accommodating different screw sizes.

3. Tip:

The tip of a screwdriver is the crucial component that engages with the screw head. It comes in various shapes and types, each tailored to specific screw heads. Some common tip types include:

a. Flathead/Slotted:

This tip features a simple, flat, and straight design with a single slot, which corresponds to the flathead screw. It is widely used in woodworking and general applications.

b. Phillips:

The Phillips tip consists of a cross-shaped design, featuring four arms meeting at a central point. It is intended for use with Phillips-head screws, commonly found in electronic devices and machinery.

c. Pozidriv:

Similar to the Phillips tip, the Pozidriv has additional smaller cross-shaped grooves between the arms. It offers enhanced grip and reduced cam-out, making it suitable for high-torque applications.

d. Torx:

The Torx tip features a six-pointed star shape, providing better torque transfer and reduced slippage. It is often used in automotive and electronics industries.

4. Shank and Handle Connection:

The connection between the shank and the handle plays a vital role in the screwdriver’s overall strength and stability. The most common types of connections include:

a. Tang Connection: In this traditional design, the shank extends through the handle, forming a tang at the end. The tang is either secured by compression or by a ferrule, ensuring a sturdy connection.

b. Hexagonal Bolster Connection: This modern design incorporates a hexagonal bolster at the base of the handle, allowing the shank to fit tightly. The bolster provides added torque and prevents twisting during heavy-duty applications.

5. Shaft:

The shaft, located between the shank and the tip, is a cylindrical section that assists in transmitting torque from the handle to the tip. It provides rigidity and stability, preventing flexing or bending during use.

6. Magnetic Tip (Optional):

Some screwdrivers feature a magnetic tip, which utilizes a small magnet to attract and hold screws securely. This feature can be particularly helpful when working in tight spaces or when handling small screws that are difficult to grip manually.

What are the parts of an electric screwdriver?

1. Housing:

The housing, or casing, of an electric screwdriver is the outer protective structure that encloses all the internal components.

It is typically made of durable and lightweight materials such as plastic or metal. The housing not only provides physical protection but also offers ergonomic design features for comfortable handling during prolonged use.

2. Motor:

At the heart of an electric screwdriver lies its powerful motor. The motor converts electrical energy into rotational force, which drives the screwdriver’s operation.

Depending on the model and power rating, electric screwdrivers may have brushed or brushless motors. Brushless motors tend to be more efficient, durable, and produce less heat, resulting in extended battery life and superior performance.

3. Battery:

Unlike manual screwdrivers, electric screwdrivers rely on rechargeable batteries to provide the necessary power.

Lithium-ion (Li-ion) batteries are commonly used due to their high energy density, lightweight nature, and minimal self-discharge. The battery is usually integrated into the handle or can be detachable, allowing for easy replacement and recharging.

4. Trigger:

The trigger is the control mechanism of an electric screwdriver, located on the handle.

It enables the user to start and stop the rotational motion of the screwdriver. By applying pressure to the trigger, you can precisely control the speed and direction of the tool, allowing for delicate or rapid screwdriving as needed.

5. Chuck:

The chuck is the component that holds the screwdriver bits securely in place. It features a mechanism that allows for easy bit changes and ensures a firm grip.

The most common type of chuck used in electric screwdrivers is a keyless chuck, which can be operated by hand without the need for additional tools.

6. Bit Holder:

The bit holder is a removable attachment that connects to the chuck and holds the screwdriver bits.

It allows for quick and effortless swapping of different types and sizes of bits, accommodating various screw heads and applications. Some electric screwdrivers may have a magnetic bit holder, enhancing convenience by securely holding the bits in place during operation.

7. LED Work Light:

Many electric screwdrivers are equipped with built-in LED work lights. These lights illuminate the work area, providing enhanced visibility, especially in dimly lit spaces or when working in confined corners.

The LED light ensures accurate screw placement and reduces the chances of errors or mishaps.
