White vinegar for quickly disassembling screw rust

The method for rapidly decomposing white vinegar by spiral rust is as follows:

1. The screw is rusted, so it can be rusted with vinegar. Vinegar is acidic and can react with trivalent iron ions in rust to generate divalent iron ions and water. It is suggested that vinegar can be added to hot water, and then the rusty screws can be soaked in vinegar water to remove rust.

2. The screw is rusty and can't be screwed down. You can find a piece of gauze tightly wrapped around the screw, and then pour some vinegar on the gauze to soak it. Wait for an hour, and the vinegar will dissolve the rust on the screw and you can unscrew it. If the screw is seriously corroded, you can knock it loose with a wrench or hammer first, and then unscrew it.

3. If there is no white vinegar, you can turn the object around and pat it. You should pat off the dust and rust inside. When the screw is loose, screw it out with a screwdriver. Relatively speaking, it is relatively easy. You can pour some oil in, which can play a role in lubrication. You can use lubricating oil or edible oil, or you can use local materials.

4, you can use brute force to pull out the screws. If there is a section exposed, you can choose this way. You should clamp the screw with pliers and pull it out hard. As long as the power is strong enough, the screw can be pulled out. When you pull it out, you should also shake it while pulling it out. Try to loosen the screws and shake off the rust, which will make the operation easier.

Classification of screws

Hexagon screws and bolts, as the name implies, are externally threaded fasteners with hexagonal heads and are designed to be rotated by wrenches. According to ASMEB 18.2. 1 standard, the tolerance of head height and rod length of hexagon-head screws is smaller than that of ordinary hexagon-head bolts, so ASMEB 18.2. 1 hexagon-head screws are suitable for installation in all places where hexagon-head bolts can be used, including hexagon-head bolts.

Socketcapscrew, also known as hexagon socket head screw or), is a kind of screw with a hexagonal inner hole in the head, which can only be tightened or loosened after inserting an hexagon wrench into the inner hole. The countersink is designed so that the screw head can rotate without being exposed to the surface of the fixed object, so it is often used in places with small surface and inconvenient use of traditional wrenches.

Machine screws are generally smaller than? English screws (4#~ 12#), usually full-toothed and turned by a screwdriver, such as slotted, cross-slotted or hexagon socket.

Wood screws, machine screws; But it can be divided into many categories according to different uses; Machine screws can be divided into longitudinal fastening screws and transverse expansion screws.
