How to skillfully unload rusty fasteners? I am afraid that many friends have encountered such problems in their daily life. Today, the editor of our work No.1 will introduce to you some knowledge about this.

Fasteners are widely used in all kinds of equipment and facilities in daily production and life. For the use of fasteners, our common problem is rust, difficult to unload, can not be screwed.

This is actually very normal, perhaps because the fastener has been used for too long, or the fastener material quality is not too good, in the face of rusty fasteners, and can not be removed, what to do? Hardware Grid provides you with the following five tips to facilitate the unloading of rusty fasteners:

1. Knock: with your hammer, corroded stainless steel nut, it is easy to make the nut loose. For example, the bicycle pedal fixed bolt nut at both ends, according to the thickness of the pedal, metal structure, master the use of nut size. The nuts between the cast iron can be forcibly slightly larger, using plastic. If you still can't do it, hit the nut in the hammer direction, and the nut can be easily removed.

2. Shock: rusty screws, do not use a wrench, six corners of the face, to prevent sliding screws or wrenches. At this point, you can use a hammer gently trembling wrench to deal with, generally can screw rusty screw in the vibration.

3. Punching: for the protection of corroded stainless steel screws on the top of some equipment, you can not use a wrench, cutting tool, the method of discharging effects is available. First, the top tightened with a hammer and a screwdriver is the influence of the direction of a flat straight v-groove.

Then, after adjusting the taper angle and the direction of rotation along the screw, you can use pliers screws. "one" or "ten" screw slide, this method may be adopted, steel wire screw clamping screw.

4. Welding: remove the device and screw the screws. The top of the broken screw usually does not use an electric drill because it will be a bad wire hole a little careless. A better way is to weld the broken wire with long iron welding. Determine that the iron cross section is determined by the diameter of stainless steel fasteners.

5, burning: some screws embroidery corrosion is very serious, using the above method still does not work, you can use "fire". Use gas welding oxidation flame screw, nut completely barbecue, and then burn red screw silk small oil droplets.

The purpose of heating the screw is to expand the screw thermally. The purpose of the drop meeting is to make the screws cold shrink quickly, increasing the gap between the screws and the stainless steel nut, the oil flows into the loose nut, but be careful if there are any plastic components nearby.
