Cleaning the threaded holes in your block is crucial for installation and proper torqueing of bolts, head studs, main studs, and any other fasteners. Using a thread cleaning chaser is fairly simple, you just run the tool through the holes, remove it, and repeat the process until the threads are clean.
Unlike a tap, a thread chaser does not cut new threads, it only cleans the existing ones. The internally threaded bolt holts can accumulate debris such as old sealants, lubricants, gasket material, and anything else that could have fallen into the bolt holes on your engine block.
Running a thread chaser through the bolt holes ensures your threads are clean so you can get accurate torque values while torqueing the fasteners in your engine build, or repair project. Get one of these in your toolbox today and use it with XDP head studs, studs from other brands, and even OE-style fasteners.
