Can a damaged thread be repaired?
Damaged threads on a screw or bolt can often be fixed by running a die over it, and if a thread's damage is minimal, it may be possible to reform the threads by running a nut up and down them, though that runs the risk of the nut fusing to the thread (galling).

Thread-repair inserts come in a variety of materials and in a myriad of designs from domestic and overseas manufacturers. Timed thread body inserts, wire coil inserts and keyed inserted make up the three major families of thread inserts you’ll likely encounter.
How to repair M10x1.25 thread?
For an M10x1.25 thread repair with a Keensert, a 12.5mm drill would be used for the M14x1.5 tap. The M14x1.5 tap would have a major diameter up to 14.4mm (an M10 repair with an S.T.I. tap would only have a 11.787mm major diameter). That’s a much bigger hole which can be beneficial in some application where severe corrosion is prevalent in the original threads. The Keensert would then be threaded into the drilled, tapped and cleaned hole with the Keensert installation tool. Thread locking compounds can be used due to its solid body design. Once set in position, the installation tool is then used to drive in the four key stakes into position. This provides the ultimate mechanical locking of the insert in place. Hence, this design sports exceptional resistance to vibration. Now the downside. The massive outside diameter of the insert makes it unviable in applications where the material around the original threaded hole is limited, such as any “thin-wall” castings. Second, the cost for a standard-steel Keensert is about 4.5 times that of a HeliCoil and more than double the cost of a TIME-SERT. If you want a stainless-steel Keensert, the cost goes through the roof being about 25 times the cost of a HeliCoil.
What size drill do I use for a M10x1.25?
First, you would drill the hole with a 10.25mm drill (a standard M10x1.25 thread would use a much smaller 8.75mm drill). Then you would use an M10x1.25-S.T.I. tap. This S.T.I. version of the tap will have a major diameter of up to 11.787mm, whereas a standard M10x1.25 tap is about 1.5mm less in diameter.
How hard is it to drill a stripped hole?
How easy or how hard usually depends on the access to the stripped hole. If you can take off the entire header and get enough access to fit a cordless drill in the area to drill out the hole before tapping, it pretty easy. I;'m guessing it would probably be an M8x1.25 thread. Compare the size and thread on one of the good bolts to a know M8x1.25 bolt to confirm.
Can you have a thread failure in the same hole again?
Done right, you’ll never have a thread failure in the same hole again.
Is stripper thread more common than ever?
As a result, it’s no surprise that strippers are more common than ever before. Since most of the threads on today’s vehicles are made of materials with just one-third to one-half the hardness of grey cast iron, it’s no wonder that more threaded holes experience thread damage than ever before.
Can Keensert be threaded?
That’s a much bigger hole which can be beneficial in some application where severe corrosion is prevalent in the original threads. The Keensert would then be threaded into the drilled, tapped and cleaned hole with the Keensert installation tool. Thread locking compounds can be used due to its solid body design.
How to get chips out of a thread?
Once the threads are cut, you need to clean out the hole. Spray it with compressed air, brake cleaner or lubricant to get all the chips out.
How do threaded parts work?
They are twisted by hand, and slowly work their way into hole being tapped. Threaded parts such as bolts, shafts, and other similar parts use dies to cut the threads. This is done in a similar manner as a tap, but the shaft of the part threads through the die as it cuts the threads.
What is a taper in a blind hole?
The taper is there to guide the tap in the hole and to slowly cut the threads in fresh material. While this is great for through-holes, where the backside of the hole is open, these only get part of the job done when you are working with a blind hole, where the hole is closed. For that, you need a bottoming tap.
What is a taper tap?
The taper tap is the most common tap design. This is the style used for creating new threaded holes. The first 8 to 10 cutting flutes of the tap are not full, they gradually build up to the full thread size. The taper is there to guide the tap in the hole and to slowly cut the threads in fresh material.
Why do taps have tapered flutes?
The tapered flutes help ensure that the tap is centered and vertical. We ran the tap all the way through the part, so that the bottom threads were touched by the full flutes of the tap. The chips in the relief grooves of the tap are called swarf, they should be cleaned off before putting the tap away.
How many flutes does a plug tap have?
The plug tap is in the middle, it uses 3-5 gradual flutes. Each tap style serves a different purpose. From the left- taper, plug, and bottoming. If you are repairing damaged threads, either of these taps will usually work, unless it is a blind hole, in which you need to use a bottoming tap.
What happens if threads don't match?
Some pitches overlap different sizes, so you have to use the chart to determine what size fastener you have. Thread size and pitch is critical to this type of repair. Using this style of pitch gauge, you can determine exactly what you have.
