Due to constant friction with the screws, the screwdriver head is a consumable accessory that needs to be replaced after a period of use. However, replacing the electric screwdriver head requires selecting the appropriate screwdriver head specification. How do you confirm the screwdriver head specification?

1. Determine the required batch header type

Firstly, it is necessary to choose the appropriate type of screwdriver head. There are various commonly used electric screwdriver heads, such as straight and cross, as well as some less commonly used ones, such as triangular, square, U-shaped, cross belt column, cross flat head, etc. When selecting, the first thing to consider is the specification and model of the electric screwdriver.

2. Determine the handle size of the required screwdriver head. Electric screwdriver heads can be divided into four types based on the diameter and shape of the handle:

(1) 4mm round handle: With a handle diameter of 4mm, it is suitable for most 800 type electric screwdrivers on the market (with a 4mm round hole for the screwdriver socket).

(2) 5mm Round Handle: With a handle diameter of 5mm, it is suitable for most 801 electric screwdrivers on the market (with a 5mm round hole for the screwdriver socket).

(3) 6mm Round Handle: With a diameter of 6mm, it is suitable for most 802 electric screwdrivers on the market (with a 6mm round hole for the screwdriver socket).

(4) 6.35mm Hexagonal Handle: With a height of 6.35mm on the opposite side of the hexagon, it is suitable for most SH1/4 electric screwdrivers and all pneumatic screwdrivers on the market (with a 6.35mm hexagonal hole for the screwdriver head socket).

3. Determine the size and shape of the electric screwdriver bit socket

The shape of the electric screwdriver head needs to be matched with an electric screwdriver in order to be used, and the size should be accurately measured, not large or small.

4. Determine the diameter of the disassembly screw

The size of the screwdriver head is determined by the diameter of the screw that needs to be disassembled. For example, if you need to disassemble an M4 screw (with a diameter of 4mm at the threaded part), choose a screwdriver head with a diameter of 4mm for disassembly.

5. Determine the size of the screw cap cross pattern path

The size of the cross pattern on the screw cap affects the sharpness of the screwdriver head. If the cross pattern is thinner, choose a sharper screwdriver head; If there are two types of patterns, priority should be given to the finer one.

6. Determine the depth of the screw hole

If the depth of the screw hole is 20mm, select a screwdriver head with a length greater than 40mm.

3、 How to install and disassemble the electric screwdriver head

After selecting the model of the electric screwdriver head, the old head needs to be removed and the new head needs to be installed. How can the electric screwdriver head be removed and installed?

1. Dismantling method: Push on the sleeve at the end of the electric screwdriver head, pull out the screwdriver head along the guide groove, release the sleeve, and then take out the screwdriver head.

2. Installation method: Push on the sleeve at the end of the electric screwdriver head, insert the screwdriver head into the spindle along the guide groove, then loosen the sleeve, and firmly cover the screwdriver head.
