Types of Thread Repair Insert

When looking for thread repair inserts, there are several different types available. Big-Sert, Locin-Sert, Recoil, and Loc-in-Sert are among the most popular. To help you choose the right one for your application, here are some common types and their uses. The first one is called a "key" insert, and it locks into the parent hole by knocking down the keys. While this might be desirable in some applications, it may also lead to slight damage to the parent thread. Additionally, it may lead to gas or fluid leakage. Ultimately, these types of thread repair inserts are deemed the most suitable for most applications.

Recoil Thread Repair Inserts

Whether you need to fix a loose screw or need a thread repair kit, Recoil has your solution. Recoil thread repair inserts are available in various sizes and thread forms, from two mm to 50 mm. They come in individual and multiple size repair kits and come in screw lock, striped, and free running styles. In addition, the company also offers kits that contain installation tools to help you complete your project quickly and easily.

 The Recoil thread repair inserts are available in stainless steel, which makes them great for fixing damaged threaded holes. The length of each insert is 1.5 times the diameter. They can also be purchased in bulk quantities. Each kit contains three to fifteen inserts and is designed for use in flanges and reduced bosses. These thread repair inserts also come in multiple sized sets. To install them in your bolt or flange, simply install them with the supplied wrench.

Loc-in Sert Thread Repair Inserts

EZ Lok brand Loc-in-Sert thread repair inserts are used in the manufacture of new equipment. They are also used in dies for plastic injection moulding and metal stamping. When the tread wears down, they are easily removed and replaced with new ones without damaging the parent hole. The patented Loc-in-Sert thread repair inserts are designed to withstand high torque levels and can even be used in tight spaces.

The inserts are stronger than the original hole tapped into the parent metal. When a thread is tapped oversize, the diameter of the insert increases, enhancing the surface area in contact with the parent metal, wire thread helical coil type inserts are typically stronger than the parent metal and can add as much as 20% load-bearing capacity. They are made from the same material as the parent metal, which is typically stainless steel.

Time-Sert Thread Repair Inserts

The use of Time-Sert thread repair inserts is a simple and effective way to make a hole in a screw or bolt thread. These inserts are self-locking, as the bottom internal threads are cold rolled to expand, and the external mating threads are pushed into the base material to lock the insert in place. After the hole is prepared, lubricate the Time-Sert driver tool with the appropriate oil, and insert the Time-Sert into the hole.

While the simplest thread repair system is a wire thread insert, a Time-Sert is a solid, machined piece of metal that is the same thickness as the original thread. This makes it an excellent option for holes that have little meat to begin with. Although it's not quite as good at stress distribution as a helical-coil type wire thread insert, it can fix a stripped thread in any material, including aluminium. In addition, it's easier to fit a Time-Sert than a wire thread insert because of its unique locking system.
