OTC has introduced an exhaust manifold stud remover, the 6982PMC Professional Mechanics Collet.
The stud remover works on threaded studs with as little as 1/4 in. exposed, ideal for gripping a small amount of metal to remove broken or frozen manifold studs. The kit is covered by a lifetime warranty and is available now in North America, the company says.
The tool includes collets in 6 mm, 7 mm, 8 mm and 10 mm sizes to remove a number of broken bolts or studs. The collets tighten within 1/16 in. of the head surface to greatly reduce tipping, OTC says.
