Holes not drilled deep enough
For the length of screw
Put a mark on drill.use tape.
Drill just past screw length to allow for counter sunk heads
Hope this rectify your problem. more
I would like to stop my kitchen fitter to do more because his work doesn't comply to my standards. We did all the ripping out of.
I hope you enjoyed reading this article and that you found these techniques useful. However, please make sure that when attempting any of these methods you take care and wear suitable safety glasses.
There are plenty of great ideas out there, in fact too many to mention, and there is no one method that works on all screws. However, I have picked 6 techniques that I thought might be useful to share, using everything from an elastic band to an impact driver!
If none of the above techniques work then using a rotary tool is another option. Securely attach a thin cutting disk to your rotary tool and start to cut a thin slit in the stripped screw. Make sure it’s deep enough to fit a flathead screwdriver, but thin enough that the screwdriver has enough to grip. If your screwdriver doesn’t fit you may need to make the cut larger, but make only small cuts; if you cut off too much of the screw, a screwdriver will not catch and you will not be able to twist the screw. The rotary tool can scatter loose metal shavings around the device so make sure you wear your safety glasses.
Stripped screws are a nightmare and try as you might, some just don’t want to come out. That’s when frustration takes over and before you know it, that once crosshead shape has turned into a big fat ‘O’.
This isn't a joke, they really to exist! Left handed drill bits are designed to be used in reverse. Choose a drill bit that is slightly smaller than the head on the screw, then put the bit in the drill and tighten. Make sure the drill is in reverse and apply firm pressure to the screw head and start the drill. Once it bites there’s a good chance that it will remove the screw.
I’m sure that we have all run into problems at some point trying to remove that pesky threaded screw that seems impossible to get out! But what are the best ways to do this?
6. Weld’er Up: This is one that can be used if the nut or bolt head is so severely stripped it can’t turn it with locking jaw pliers, or if the head is completely broken off the bolt. Simply take a nut and a bolt of a slightly larger size, and tack weld it to the bolt body. Once you have it tack welded, fill the nut with weld and run a bead around the base of where it meets the bolt body. This allows you to put a socket on the bolt again, as well as puts heat into the bolt that will allow it to expand and contract, breaking some of the corrosion. We prefer to use a MIG welder to do this job as it allows for a little more control than with a stick welder. [links]
Below are the top 10 ways our friends at Eastwood have come up with to deal with getting these suckers extracted without wrecking the precious part they are in: here
Welding a new bolt to the stud or broken bolt can provide a surface for the wrench to grip. The heat from welding the bolt onto the broken fastener can further help by breaking any corrosion bonds between the threads. more
One of the biggest frustrations when disassembling a vehicle for restoration, or even repair, is the dreaded seized or stripped bolt. Stuck hardware occurs when a bolt or nut gets corrosion between the threads and they won’t budge. Many times this leads to breaking the bolt off and having to drill and retap the hold or trying to remove it with a bolt extractor. We won’t even mention what happens when the drill, tap, or extractor breaks off in the same hole. more
5. Drill’er out: This is the same concept as the relief cuts with a couple small twists or surprises that can occur along the way. We like to use this one as one of our last ditch efforts. It may be the last resort if the bolt has broken off flush with the surface. Using a small drill bit, drill all the way through the bolt lengthwise. This uses a bit of the other methods too. It heats the bolt by drilling it, and it also makes a hollow portion in the bolt so it can contract more as you attempt to remove it. We’ve had times where just drilling the bolt will allow the frozen bolt to turn out quite easily. Other times you may have to keep stepping up your size of the drill bit until you are just a bit smaller than the diameter of the bolt. At this point you may be able to carefully chisel or break the bolt apart in the hole. Then extract the pieces and clean the threads back up with a tap set or a universal tap tool. here
Removing bolts with rounded heads, stripped threads, frozen, or even broken flush with the material like the one shown here, can be a real challenge. Here are ten ways to help remove problem fasteners.
For a screw that’s rusted and seized in place, spray it down with penetrating oil first, let it soak in for several minutes, then try unscrewing. [links]
Use locking priers (aka Vice-Grips) around the head. Once locked in place, rotate the pliers counterclockwise and back out the screw. This method also works when the head has broken off mid removal. here
Put the tip of a flathead screw driver (or anything firm and flat) behind the screw-head, and while you unscrew with a screwdriver, pull the screw head toward you, helping the screw to back out as you’re turning the driver. (Sue, I think this method will work best for you.) more
At any rate, here are several ways to remove a stripped or stubborn screw. more
Basically, this is a bit used on a drill that first burnishes/reams a hole in the screw head, and then another extracting bit fits in that hole, bites into the screw, and allows you to unscrew. There are various sizes and types, but the concept works the same. I like the extractor kits where the drill (burnishing) bit is on one end, and the extractor end is on the other. here
“I am putting together a LP gas fire pit table for the patio. The legs (metal) attached to the tabletop (metal) with hex screws. One of the screws will not tighten in its hole. It just keeps turning endlessly. I tried to back it out by unscrewing it but I cannot get it to back out either, again it just turns and turns. Have I stripped it? How do I get the screw out to use a different screw? – WYSK Reader Frustrated in SoCal, Sue
