## Description

Product Description OEMTOOLS 25648 Fix-A-Thread Spark Plug Saver Inserts are designed for rethreading in all materials such as alloys, steel, plastics, magnesium, and more. Specified for automotive, military, aviation and other similar usage, these inserts are made from 18-8 stainless steel wire with a diamond shaped cross section wound to the shape of a spring thread. This positive mechanical locking feature keeps threading in place so there is no loss of compression over time, like you may see with less sophisticated inserts. The corrosion-resistance steel alloy construction extends thread life, even after repeated disassembly and reassembly. Similarly, the high tensile strength wire construction eliminates thread failure due to stripping, vibration, and fatigue. Extreme heat resistance maximizes tapped thread strength under any conditions. Please note that installation requires use of a thread insert tool. These 6 14 - 1.25 inserts are designed for use with a complete thread restorer kit containing a quality intermediate tap, thread repair tool, and easy to follow instructions. When you need more spark plug savers for your thread chaser set, the OEMTOOLS 25648 Fix-A-Thread Spark Plug Saver Inserts are here to save the day. From the Manufacturer OEMTOOLS Fix-A-Thred Inserts are designed to repair stripped threads on "Non-Tapered Seat" spark plugs and for rethreading in all materials such as alloys, steel, plastics and magnesium. They are specified for military, aviation and other similar usage. Inserts are made from high quality 18-8 stainless steel wire with a diamond shaped cross section wound to the shape of a spring thread. Each kit contains a quality intermediate tap, quantity of inserts and easy-to-follow instructions.

Review: That it works with no problem. - It seems I have become the repair man for my area. People just drop off items to be fixed and hope for the best. The inserts have saved chain saws, lawn mowers. and garden tractor form the scrap yard. It also makes friends think I can fix anything. The inserts are so easy to use and save time on repairs.
Review: They do what they are supposed to do - I give these 5 stars as they do exactly what they are intended to do and come in at a cheaper price than the name brand. The length variety seems to cover all applications I have come across and fit very well. I would encourage anyone looking at these to review them carefully along with the insertion tools that are available. Personally, I suggest not getting the OEMTools 25647 kit, but rather getting the Heli-Coil 5334-14 which works perfectly with these inserts. There difference is that the OEMTools version only works with a wrench, which will not at all work in deep or hard to reach locations. The Heli-Coil kit allows you to use a 3/8 ratchet and extension to get where you need to be. This is absolutely critical in many applications and the Heli-Coil kit will work in all those applications. I assume that buyers looking at this already know how to use them, so no need to touch on that. These inserts are the same quality as the insertion kits that use this style insert and is the cheapest brand I can find without sacrificing quality. If you use this style, I do not believe you can go wrong with this refill of inserts.
