Helicoil Type Thread Inserts 7/8 x 14tpi BSP x 1.5D Stainless Steel Pack of 5

Compatible with Recoil and Helicoil Kits these VCOIL Wire Thread Inserts are manufactured from high quality chromium nickel stainless steel, to aircraft and aerospace standards. Due to the narrow and exact tolerances, the newly repaired thread is stronger than the original one!

Please note that BSP vcoils are only available in 1.5D length.

This is not however 1.5 times the actual thread diameter..it is 1.5 times the numeric value of the coil thread.

So for example a 1/4" BSP thread has a 1/2" outside diameter, but the  insert is 1.5 times 1/4" long..being 3/8", and not 1.5 the thread diameter which would be 3/4".
