Miscellaneous Bolts, Nuts, Locknuts, Fittings, Clips, Plugs & Hardware Items

This category includes all kinds of small hardware parts used in diesel engine systems. You'll find bolts, nuts, spacers, clips, plugs, screws, springs, and fittings — some for Cummins, some for Dodge, some for Caterpillar.

These are the pieces that hold everything together or keep it sealed the way it should be. Whether you're doing a full rebuild or just replacing a stripped plug or missing spring, this is where you’ll find those parts that are hard to search for but necessary to get the job done.
