Peterbilt 379 Dash Nuts & Screws

Frequently Asked Questions About Peterbilt 379 Dash Nuts & Screws

What are these dash nuts and screws used for?

These fasteners are designed to secure interior dash panels, trim pieces, and switch or gauge covers inside the Peterbilt 379. They replace worn, stripped, or missing hardware that can cause dash components to rattle, loosen, or fall out of place over time.

Will these fasteners fit my specific Peterbilt 379 model year?

Most dash nuts and screws in this category are designed to match the factory hardware used across Peterbilt 379 production years, but dash configurations can vary depending on the trim level and interior options installed at the factory. We recommend comparing the thread size, head style, and length to your original hardware before ordering to confirm a proper fit.

Are these OEM parts or aftermarket replacements?

This category includes a mix of OEM and aftermarket fasteners. Product listings specify whether an item is a genuine Peterbilt part or an aftermarket equivalent, so you can choose based on your preference for factory-original hardware or a more budget-friendly alternative.

What material and finish are these nuts and screws made from?

Dash nuts and screws are typically made from steel or stainless steel and may feature a plated or chrome finish depending on the specific part. The finish helps resist corrosion and keeps hardware looking clean where it may be visible along dash trim and panel edges.

Do I need any special tools to install these fasteners?

Installation generally only requires basic hand tools such as a screwdriver, nut driver, or small wrench, depending on the fastener type. Since these nuts and screws are replacing existing dash hardware, the original mounting points and access panels should already be in place, making removal and installation straightforward for most do-it-yourself installers.
