Experience in buying bolt tightening guns for newbies

But choosing to buy a quality bolt tightening gun, guaranteed to suit your work needs, is not a simple thing. With many years of experience in the field of providing these devices, EMIN can help you answer your questions and support you in choosing the most suitable type of pneumatic hand tools, follow along in the article below. here it is!

Choose according to work needs
Choosing a bolt tightening gun based on job needs is very important, especially when you have to consider the size of the socket head and the appropriate tightening force for each type of bolt. Each bolt size, such as M5 (8mm), M6 (10mm), M8 (13mm), requires its own standard tightening torque to ensure safety and efficiency. If the tightening force is too strong, you can damage the bolt threads, but if it is too weak, the tightening process will be difficult and affect the durability of the device.

If you are operating a garage specializing in repairing scooters, motorbikes, or small passenger cars, you should choose a bolt tightening gun with sufficient force, suitable for common bolt sizes. This not only makes the job easier but also helps save costs, because guns for these vehicles often cost less than those used for passenger cars or heavy trucks.

Classify:

- A gun with a 3/8 inch head size is often used to open screws from 6 to 10 mm in size.

- 1/2 inch gun is suitable for screws from 10 to 24 mm.

- For larger screws, from 24 to 33 mm, you need to use a 3/4 inch gun.

- As for larger screws, from 33 to 55 mm, the 1 inch gun will be the best choice.

Rules when buying:

Currently, most bolt guns use compressed air to operate, so users need to follow some important principles before using. First, it is necessary to ensure that the amount of compressed air is sufficiently charged during gun operation, and it is necessary to check regularly to maintain the necessary air source for the equipment in the workshop.

The pressure of the air compressor needs to match the required pressure of the bolt gun. Normally, equipment in the workshop will operate at a pressure of 4-6 bar or 8-10 bar. Therefore, the worker needs to adjust the compressed air pressure to meet the requirements of each type of gun. Otherwise, the gun will not develop the correct tightening force according to the design.

For workshops specializing in truck repair, it is often necessary to use air pressure higher than the standard level due to the specifics of the job and the truck's condition. When using pneumatic bolt tightening guns, customers need to pay attention to the quality of compressed air to avoid dirty air damaging the components inside the gun.

Low-quality bolt guns are often not durable enough to operate in high-frequency working environments. Therefore, before buying, customers need to pay attention to the brand and choose products that have been highly appreciated for their quality by many users.

The operating principle of a pneumatic bolt gun depends on the amount of air supplied. When tightening screws, it is necessary to adjust the force just enough to avoid danger to workers and equipment. On the contrary, when removing screws, you need to use the maximum tightening force to easily do the job.

For tasks such as removing car tires, where high frequency of work is required, you should choose good quality bolt guns, guaranteed to withstand high pressure and operate effectively for a long time.

Note before buying

First of all, carefully check the quality of the air compressor you are using. Why is this important? Because the air compressor is the source of compressed air for the gun to operate, and each type of gun will require different levels of air pressure.

- With a 1-inch pneumatic bolt tightening gun, you need to ensure the air source has a pressure of 10 to 12 bars.

- A gun with a 3/4 inch tip will work best with a pressure of 8 to 10 bar.

- For 1/2 inch head guns, commonly used for scooters and small passenger cars, a gas source of 6 to 8 bar is sufficient.
