Fasteners hold the engine together and matter far more than their cost suggests, with critical joints depending on a specified grade, torque figure and tightening sequence. This group covers bolts, screws, studs and nuts, washers, clamps and clips, dowels and pins, plugs and threaded adaptors. Critical joints including cylinder heads, connecting rods and main bearing caps use fasteners specified to a defined grade and, in many cases, torque-to-yield bolts that are single-use. Machine-mounted engines also suffer fastener loosening from vibration more than fixed installations, so checking torque on ancillary mountings at service is worthwhile.

Torque-to-yield bolts are single-use and must be replaced whenever the head is removed. Reusing a stretched bolt risks under-clamping the joint.
Continuous vibration and shock loading from machine work loosen fasteners more readily than in fixed installations. Checking torque on brackets and mountings at service prevents consequential damage.
No. Engine fasteners are specified to a grade and often a defined stretch behaviour, and a lower-grade substitute can fail under load.
