Which is better HeliCoil or Time-Sert?
After doing a bit of research it sure seems to me that the Time-Sert is the clear choice for a more full-proof 'permanent" fix. The only advantage to a Helicoil I found, is that it is cheaper. Being in the industry for a little while I have seen time and time again, that cheaper is never better.
How strong is blue Loctite?
medium adhesion strengthBlue Loctite threadlocker is considered to have medium adhesion strength. It can be disassembled with high torque, but it is easier to disassemble with special chemicals and/or heat. It is available as a tape, semisolid, or liquid form, and once applied to the threads it will cure in 24 hours.

How to repair stripped threads in aluminum?
If there are heat-sensitive objects nearby you may not be able to use this option. If you’re fine with heating up the area you can fill then retap the hole . This will help you repair stripped threads in aluminum.
How to make a solid surface with aluminum?
Try an aluminum braising rod. If you are able to you can heat up the area and use an aluminum braising rod. The process is almost like soldering where the aluminum melts then cools to create a solid surface. You have to heat up the surface to a temperature where the aluminum rods will melt.
How to make a bolt hole snug?
Just like the the copper wire above aluminum foil can be used in the same fashion. Tear a few pieces of aluminum foil off and fold them over. Place them down in the bolt hole and after a few twists of the bolt it should start to become snug.
What is JB weld?
JB Weld is usually a 2 step epoxy that can be used to join things together permanently. Alternatively, you can use the stripped thread repair epoxy to fill the hole and tap it afterward. If you are not worried about being able to remove the bolt later on you can put the JB Weld on the bolt and tighten it down.
What is a helicoil thread?
If neither of the options above are doing it for you can use a Helicoil. A Helicoil is a coil wired thread insert. The coil replaces the original threads. Essentially you drill out the hole with the correct bit size. You can then tap the hole and insert the coil. After the coil is inserted you then bust off the tang.
Why do bolts lose their strength?
Over time bolt s and threads sometimes lose their strength. Due to friction or corrosion, the threads can deteriorate. Having these weak threads can prevent you from being able to tighten down a bolt. The first option is looking at the bolt hole. If you have some extra distance that the bolt doesn’t cover you may be able to use a longer bolt. If there are some decent threads that your longer bolt can reach you may be able to tighten it down.
Can you drill a hole in a bolt?
If most of the threads have been a victim of damage you may be able to increase the size of the hole. As long as there is enough room on the outside you may be able to drill out a larger hole. This will allow you to rethread the hole and give you the ability to use a larger bolt.
What happens if you use a fine thread bolt in a coarse thread hole?
Mismatched Bolts and Holes: Using a fine-thread bolt in a coarse-thread hole or a metric bolt in an SAE hole can result in interference and stripped threads as the pieces try to conform to each other.
What happens if you misalign bolts?
Misalignment: If parts are misaligned during assembly, the bolts may not go straight into the holes, resulting in cross-threading or deformed threads.
What is a thread chaser?
Thread Chaser: A thread chaser rolls and reforms the deformed threads. If possible, chase the threads starting from the undamaged section. This can be done for spark plugs or caliper bolts, for example.
Can you drill and tap a hole?
Drill and Tap: You can drill and tap the hole larger to accommodate a larger fastener. Going up one or two sizes is allowable in many circumstances, but be sure to use the correct drill bit to retain the strength of the attachment. Keep in mind that tapped threads don’t retain their strength as well as chased threads because a tap may remove too much metal. Nevertheless, a tap and die set is a necessary addition to anyone’s toolbox.
Can you assemble a bolt with stripped threads?
It’s only a matter of time before you run across a stripped bolt-hole or stripped threads in your DIY repair project. And if the threads are stripped, you can’t assemble the parts and achieve the correct torque. Here’s why this issue occurs and how to fix stripped threads so you can reassemble the components correctly.
Can you use OEM bolts?
Epoxy: For low-torque applications, high-strength epoxy can allow you to use the OEM bolt size. After cleaning and applying a release agent to the bolt, put epoxy into the damaged hole and on the bolt. Threading in the bolt will force the epoxy into the existing threads. Once the epoxy cures, install new bolts as needed.
How to align a tap handle?
Align the tap attached to the tap handle over the cross threaded or stripped hole. For right hand screws, insert tap into tap hole as you slowly rotate the tap handle clockwise. 99 percent of of holes, screws, and bolts are right hand screws. If you know your hole is a left hand thread, rotate counterclockwise instead of clockwise.
How many turns does a tap handle rotate?
Rotate the tap handle clockwise two full rotations, then counterclockwise 1/4 of a turn.
What thread repair is used for a larger locking insert?
Another thread repair is Keensert which, if you have yet more metal because it's a larger device, a locking insert that doesn't require delicate use of Red Loctite to keep it in place.
What type of bolt do tripods use?
Depends on the size of the screw and how much material you have to work with. If this is a clamp bolt, cheap tripods use screws going directly into the casting. Quality units either use a captured nut, Nyloc nut and eccentric toggle or a tee-head bolt with threaded knob.
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.
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.
What is the hardness of cast aluminum?
The highest hardness cast-aluminum alloys are used in block and cylinder heads. These will typically have a range of hardness from 75-to-85, about the same as 6061-T6. Only 7075-T6 aluminum alloy has a hardness of 150 which is on par with grey cast iron.
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.
