Thread Repair Kits

Thread Repair Kits Information

A thread repair kit typically consists of one or more drill bits, taps, thread inserts and installation tools, though there are also specialist kits available for more specific applications. The most common thread repair kits are designed to replace damaged internal threads with a coiled insert, which provides a more secure repair than would be achieved by rethreading the damaged part. To install the insert, the original thread must be drilled out with an oversized hole and then tapped with the correct thread to accomodate the new insert, which is then screwed into the hole, ready to acommodate the original fastener. Note that thread inserts typically have a tang which must be broken off inside the hole once they are installed, so care should be taken to avoid foreign object damage when working on complex or sensitive machinery.

Recoil have a popular range of thread repair kits and we stock a comprehensive selection for metric, UNF, BSP and BSF threads. All of these kits come with the correct size of drill bit and tap along with installation tools so you can get to work with a minimum of fuss. We also stock thread repair kits from Sealey and Draper, including a number of more specialist sets for the automotive trade.
