What if the screw slips and cannot be unscrewed? Many times, when you want to repair a thing, you will encounter this situation. What should you do? In fact, it is quite simple. Xiao Rui summarized five reliable methods to remove slippery screws, starting with the least destructive method, and then turning to the more destructive method. The method you choose will depend on your situation and the importance of removing stubborn sliding screws.
01
elastic
This method is to increase the friction between the screwdriver and the screw and prevent the screwdriver from slipping out when screwing.
Any rubber band can be used, but wider ones work better because they provide the maximum contact area between the screw head and the screwdriver head.
Place the rubber band on the screwdriver head and tighten it until it is not loose, and then gently insert the screwdriver head into the screw head of the sliding wire.
If the screw does not slide completely, the rubber band will help to fill the area where the screw has slipped and provide friction where necessary, so that the screw can be removed.
02
Electric drill
If the screw is not completely sunk into the material, try using an electric drill.
Open the chuck of the drill bit and place it on the screw head, then tighten it by hand to fix the jaw of the chuck on the screw. Set the drill bit to reverse direction, and then hold the electric drill handle and press the switch. Here, be sure to hold the electric drill tightly to avoid the electric drill falling off and hurting yourself because the screw is too tight.
This applies to almost any type of screw or bolt seizure as long as the jaw can grasp a portion of the head.
03
Screw extractor
This method is applicable to stubborn screws. Screw extractors are a good choice because they are threaded in the opposite way to screws - screws are right-handed and screw extractors are left-handed.
There are several different sizes of screw extractors. You need to select the appropriate size, install the extractor into the drill bit, check and tighten the collet.
Set the drill bit to reverse. Since the extractor is a reverse thread, this means that when reversing the drill bit, the extractor drill bit will drill into the screw with sliding thread and bite into the screw head, continue to reverse the drilling, and the extractor will start to reverse the rotation of the screw and withdraw it from the material.
04
Make a cut
What is more destructive than the screw extractor is to cut a notch on the threaded screw head with a cutting tool. However, it should be noted that depending on the depth of the screw in the material, the cut may damage the surrounding surface.
Use a cutting tool to cut a notch on the head of the screw similar to that used by a slotted screwdriver. Then use a slotted screwdriver to screw out the screws.
05
Cork cutter
Place the cutter in the drill and position it over the screw. Then connect the cutter with the wood,
Remove the cutter and its debris to see if the screw head can be accessed for removal.
