Components & Hardware For Peterbilt Trucks

From frame bolts and mount hardware to cab clips and body fasteners, keeping a commercial truck properly assembled requires a steady supply of components and hardware that can be hard to source quickly when you need them. Our components and hardware selection covers the broad range of mechanical and structural fasteners, clips, and small assemblies that keep a Peterbilt together through years of high-mileage operation.

Frequently asked questions about components & hardware

What hardware do I need to keep on hand for routine Peterbilt maintenance?

At minimum, a well-stocked truck maintenance supply should include assorted metric and SAE bolts in Grade 8, stainless steel and zinc-plated nuts, flat and lock washers in common sizes, cotter pins and roll pins, hose clamps in a range of sizes, and common electrical connectors and terminals. Having these on hand avoids downtime while waiting on a single fastener order, and most items are inexpensive to stock in bulk.

Are metric or standard fasteners more common on Peterbilt trucks?

Peterbilt uses a mix of both, which reflects the reality of commercial trucks built with components sourced from global suppliers. Cab hardware and body components tend to use SAE fasteners, while engine and some drivetrain components use metric fasteners that match the specifications of European-origin parts. Carrying both standards in common sizes is practical for any truck maintenance operation.

What's the best way to deal with seized or corroded hardware on a high-mileage Peterbilt?

Penetrating oil applied the night before the repair — or at least several hours in advance — is the most effective approach for seized hardware. Heat from a torch is highly effective on stubborn fasteners when used safely away from fuel lines, wiring, and other heat-sensitive components. For corrosion-prone mounting locations like frame hardware and exhaust components, replacing seized hardware with stainless steel or coated fasteners at reassembly reduces future service headaches.
