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, with torque-to-yield bolts on many joints that are single-use items. On continuously running engines opened at scheduled intervals, fastener replacement is part of the overhaul routine rather than an exception, and MWM publishes both torque figures and tightening sequences that must be followed together.
AMS Parts supplies a wide range of fasteners & hardware components for MWM engines used in power generation, marine, and industrial applications. Browse the full range below, or contact us for specific requirements.

Torque-to-yield fasteners are single-use and replaced whenever the joint is opened. On engines overhauled to a schedule, this is a routine part of the parts list rather than an exception.
No. Engine fasteners are specified to a grade and often a defined stretch behaviour, and a lower-grade substitute may hold on assembly then fail under sustained load.
It distributes clamp load evenly and prevents distortion of the component. Tightening out of sequence is a common cause of repeat gasket failure.
