Prepare your engine block for re-assembly with the XDP Thread Cleaning Chaser (M12x1.75) XD40125TC. This is a must-have for anyone working on their engine. Cleaning threaded holes is crucial whether you're installing aftermarket head studs, main studs, factory-style bolts, or any other fasteners. The purpose of a thread chaser is to clean the internally threaded holes in your engine block. To use a thread chaser is simple, you just run the tool through the hole and remove it, repeating this process until the threads are completely clean.

Unlike a tap, a thread chaser is not meant to cut new threads, only clean the existing ones. It is important to clean out debris such as old sealants, lubricants, gasket material, and anything else that could have fallen into internal bolt holes in your engine block. Performing this task will gives you confidence in your work during engine assembly. A thread chaser allows you to ensure that the internally threaded bolt holes are clean. Clean threads provide you with accurate torque readings while torquing the fasteners in your engine build, or repair. Put this thread chaser in your toolbox and use it with OE-style bolts, XDP head studs, and even studs from other brands.
