Dusted screw, how to remove? Have you ever had to


Have you ever had to remove a screw with a dusted head? How did you solve it? In addition to clogged conduits, professional electricians still have to deal with stripped screws. In this article, the World of Electrical shows how to remove a hex bolt with a dusted head.

When performing electrical maintenance on electric motors, compressors, ceiling fans, there is a great possibility of encountering a dull hex screw. To remove these screws many professionals spend the time that could be used in other parts of the task. But with the right tools, it is very simple to remove damaged screws.

Reasons for hex bolt dusting

The screw is a fastening element formed by a threaded cylindrical body and ahead, and can have different shapes. Used in the non-permanent joining of parts, thus being able to easily disassemble or assemble the joined parts, just tighten or loosen the screw.

However, some professionals when tightening the screw end up damaging your head, for not paying attention to the size of the spanner or groove you are using. The hexagon screws are manufactured in different sizes and the spanner and groove are also available. The most common mistake is to use a wrench with dimensions in millimeters to remove a screw with dimensions in inches and vice versa.

Hexagon screws can be manufactured in the metric or imperial system, so we must pay attention when tightening or loosening screws or even measure their dimensions with a caliper to avoid any chance of error. Generally, spanner and groove keys indicate the standard measurement on your body to be used to tighten or loosen the hex screw. Another mistake is to tighten or try to loosen the screw with the larger wrench.

Three Methods for Removing Dusted Hex Bolts

When the hexagonal screw is new the key fits perfectly well, but when we try to put the spanner on the dusted screw and try to turn it, the key goes right through and does not turn the screw. Knowing how difficult it is to remove a screw with a dusted head, we decided to separate some methods to make your life easier in these situations.

How to Remove Dusted Hex Screw – Pressure Pliers

The first method we are going to show you is to remove the hexagon screw when it is practical with a round head. It will be necessary to use pressure pliers to remove the dust screw. The pressure pliers have a mechanical system that makes it possible to secure the head of the dusted screw.

To remove the damaged screw with pressure pliers, first, we will adjust the pressure plier nozzle by means of the screw that makes the adjustment of the plier tip, according to the size of the screwed head of the screw. In the case of thinner screws, tighten the plier’s screw, thus closing the pressure plier nozzle more and more and if you need to open the nozzle for larger screws, loosen the pliers screw. After adjusting the opening of the nozzle of the pressure pliers to hold the head of the dusted screw, the force that the pliers exert holds the screw very well, so just turn and remove the screw.

The second method for removing a screw with a dusted head is using a file. A file is a hand tool, formed by a hard steel rod and with grooves, which is used for rough parts. The tool to remove the screw with the file is to thin the screw head until it is in a square shape. After shaping the screw head, just use a wrench to remove the screw.

How to Remove Dusted Hex Screw – Bolt Grip Screw Extractor

The third method for removing dust is using the Bolt Grip screw extractor. Made of high carbon steel, the Bolt Grip screw extractor is suitable for removing damaged, rounded, rusted bolts and nuts, etc. The Bolt Grip screw extractor is a hand tool, which, thanks to the internal shape in a conical loop, when rotating the Bolt Grip, the internal claws enter inside the screw head, thus removing any dust removed.

The Bolt Grip Screw Extractor resembles a socket for a ratchet wrench. To use the Bolt Grip is very simple, first place the Bolt Grip on top of the dusted screw and with a wrench on top of the Bolt Grip screw extractor, turn the key in the direction of displacement of the screw, thus the Bolt Grip locks by removing the screw without much difficulty.
