How to Remove Damage screw❗️

 How to Remove Damage screw

1.Penetrating Fluids,

The first line of offense in removing seized fasteners —before you damage them completely, is the use of penetrating fluids.

penetrating fluid is high in solids and low in solvents. A higher solid means greater lubricity and ability to penetrate deeply into the tiny cracks and fissures, forcing its way between the threads, the rust and the mating hole. Penetrants with a high concentration of solvents, such as the WD-40 usually evaporate or dry on the surface before much penetration can occur

When you try and remove the fastener, start gently at first, you’re trying to crack the last points of contact that’s binding the threads.

2.Friction Enhancers

Friction enhancers work by adding microscopic structures to a solution that ‘fills in the damaged areas allowing torque to be applied. There is a product on the market sold under the trade name EZ-Grip

Insert the screwdriver into the damaged drive socket, apply pressure and wiggle the screwdriver until a good purchase is established

3.Head Improvisation & Hand Tools

Your first option is to try and get the trusty locking pliers around it In any case, the trick is to have enough squeeze pressure to keep the tool in place while you try to turn it. Any slippage will only increase the damage. So caution is essential,

4.After The Head Is Gone

On countersunk screws and fasteners which have been twisted off and don’t have anything left to grip, there are basically two choices:

Drill them out and retap, repair  or replace the original thread or use a broken bolt removal or extraction tool. It is advisable to file the top of the fastener flat and to centre punch to keep the drilling as on target as possible.

5.Extractors

there are several designs of extractors available and a specific size extractor must be matched to the specific size screw or bolt. One style requires  that a separate drill bit is used to drill a pilot hole into which the extractor is inserted.

The material that most extractor tools are made of as much harder and therefore more brittle than your typical steel bolt or screw, making them quite delicate and susceptible to breakage —making things even worse. 

you must first drill the actual pilot hole and it must be true and square so the extractor fits properly and so as not to damage the bolt’s threads.
Some like the Drill-Out and Grab-It, come with an integrated drill point for simple, two-in-one-step operation.

This type of extractor includes both a drill point and a friction removal tool and are designed to turn in a left-handed direction.
