Includes Free Shipping. TIME SERT 4800 BS Metric Head Bolt Thread Kit 12x1.5 for oversize repairs. Has move-able stop collar which allows this kit to be used on more applications. It's common that head bolt threads are not near the surface, this tooling is long enough to allow inserts to be installed down below the surface in the same area of the original threads. The inserts are 30mm long which is a very common length requirement for head bolt threads. If working on a hole that has not been previously repaired use the Time Sert 4800 Kit.

This BS (Big Sert)kit which has an oversize outside diameter is commonly used when Heli-Coil or similar type thread repairs have failed. 10 inserts are included - PN 52155.
