Can you fix damaged threads?
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).

When should I use Loctite?
By far, the best reason to use a threadlocker solution is to prevent the accidental back off of fastener assemblies due to vibration. While not necessary in all applications, solutions can also be used any time a nut and bolt are placed together.
How long does Loctite 272 take to dry?
Product Details Used to prevent loosening and leakage of threaded fasteners. Typical applications include high temperature locking and sealing of studs, nuts, screws, bolts and fittings. Cure Time: Up to 72h depending on the substrate used and the temperature.
Why apply release agent to fastener threads?
Apply a coating of release agent to the fastener male threads to help prevent the epoxy compound from bonding to those threads during the curing process.
What causes thread damage?
Thread damage can occur as the result of one or more of these factors... Use of incorrect bolt torque specifications. Cross-threading or improper installation of fastener. Use of incorrect fastener size or thread pitch. Thread galling caused by engagement with fasteners with a similar material hardness.
What is epoxy compound used for?
Epoxy compound is used to repair many common sizes, types, and grades of threads. One repair kit is used for all thread sizes. Can be used in-place in awkward, difficult-to-access locations, if necessary, in a variety of applications. Epoxy compound is used to repair threads in most metals.
What are some factors that may require a custom thread insert design?
Some factors that may require a custom thread insert design include... Non-standard material of manufacture. Non-standard thread type and/or pitch. The dimensions of the required insert (wall thickness, diameter, or length) is not offered as a standard product.
What is thread insert?
In many situations, thread inserts are ideal to repair stripped threads. Thread inserts are also commonly used in new part designs because of the many benefits that they offer.
What is rusting in a threaded hole?
Rusting (oxidation) or dissimilar metal corrosion of the engaged fastener in the threaded hole.
How to cut new threads in hole?
Cut new threads in the hole by thread milling or using a tap.
What is a thread repair insert?
Thread repair inserts, allow for threads to be repaired, recreated, or reinforced to the original bolt size and pitch. Solid inserts which are often made of stainless steel or carbon steel, can not only be used to repair damaged threads but also to reinforce soft base metals like aluminum to be able to take a much higher torque.
Do self tapping inserts require a pretapped hole?
Self tapping (gardsert/seal-lock/ensat) Installation: The easiest method of all, these types of inserts do not require a pretapped hole, as they create their own threads as they are installed. They also do not require special installation tools and utilize a normal nut and bolt for installation.
Can you fix threads?
There are many not so ideal ways of fixing damaged threads by way of oversizing and cross threading; but what a lot of people don’t know is that there are many engineered solutions to properly fixing damaged threads. Even more problematic is that most people are only aware of coil based repair kits (like helicoil or permacoil).
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 is thread repair insert?
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.
What is a time-sert?
For applications that will benefit from a large-diameter insert or when you are replacing a standard TIME-SERT, TIME-SERT offers a line of oversized BIG-SERTs that are thicker wall and use an oversized S.T.I. tap. For example, an M12x1.25 S.T.I. tap would be used on an M10x1.25 BIG-SERT insert.
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.
Do time-serts have tangs?
Second, there is no tang for locking. TIME-SERTs use a special tool to lock the bottom threads into the threaded repair hole. Since TIME-SERTs are a solid body, thread locking compounds can be used on the inserts outer threads for additional strength without it affecting the inside threads and fastener.
Is threading harder than fasteners?
While the materials where threads live have become softer, the materials used for fasteners have in many cases become harder. In fact, some of the super-alloys used in high-performance head studs and rod bolts have hardness levels approaching that of tap (every try to drill out a broken tap?). 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. It’s been said, “If a threaded hole in a softer metal uses a fastener that is installed and removed on a regular basis, a harder-material insert is a must.” Unfortunately, the cost and time involved with installing inserts at an OEM level means that it will never happen on a large scale. There may be a few key, high-stress locations in an engine block or suspension component, but 99 percent of all the threaded holes will not come from the factory reinforced with an insert.
