Threaded StudThis stud is an aftermarket replacement threaded fastener installed semi-permanently into a casting, used in exhaust manifolds, head bolts, and accessory mounting where a stud-and-nut joint outperforms a through-bolt. Service techs replace studs when threads gall or break during disassembly, since drilling out a snapped stud is one of the worst jobs on a forklift engine. Stocking studs ahead of a manifold service is cheap insurance. Sold as an aftermarket replacement, contact us to verify thread, length, and grade before ordering, since stud strength must match the joint application and substituting a lower grade leads to immediate failure.Aftermarket replacement part, cross-references original part number AC0261973.Need help confirming fit?
