Frequently Asked Questions About Freightliner Century 112/120 Dash Nuts & Screws

What size nuts and screws do I need for my Freightliner Century dash panel?

Most Freightliner Century 112/120 dash panels use #10-24 screws for the main panel attachment points and 1/4"-20 screws for heavier components like the instrument cluster. The most common lengths are 3/4" and 1" for standard dash panels. We recommend checking your specific model year as some variations exist between 1996-2004 and 2005-2011 models. When in doubt, our stainless steel variety packs include the most common sizes needed for a complete dash installation.

Are stainless steel or chrome-plated screws better for dash applications?

Stainless steel screws are the preferred choice for dash applications due to their superior corrosion resistance and durability. While chrome-plated screws offer a shiny appearance initially, the plating can chip or wear off over time, especially in high-vibration environments. Stainless steel maintains its appearance and won't rust, even if scratched during installation. For visible areas, we offer polished stainless steel options that provide both aesthetic appeal and long-lasting performance.

How many screws and nuts do I need for a complete dash removal and reinstallation?

A typical Freightliner Century 112/120 dash removal requires approximately 25-35 screws and nuts, depending on your specific configuration and accessories. The main dash panel uses about 12-16 screws, the instrument cluster requires 4-6, and additional components like switch panels, vents, and trim pieces account for the remainder. We recommend purchasing a few extras as these small fasteners are easy to drop or lose during installation.

Will these nuts and screws fit both Century Class and Columbia models?

While there is significant overlap, Century Class and Columbia models do have some differences in their dash fastener requirements. The Century 112/120 models from 1996-2011 use specific thread pitches and lengths that may not be identical to Columbia applications. Our Century-specific fasteners are guaranteed to fit Century 112/120 models. If you have a Columbia, we recommend checking our Columbia-specific section or contacting our support team with your VIN for exact fitment verification.

What tools do I need to properly install dash screws without damaging the plastic?

Proper installation requires a magnetic screwdriver or nut driver to prevent dropping fasteners behind the dash. Use a torque-limiting screwdriver or exercise caution with power tools, as over-tightening can crack plastic dash components. We recommend hand-tightening to snug, then an additional 1/4 turn. For nuts behind the dash, a flexible magnetic retriever tool and a 1/4" drive ratchet with appropriate sockets work best. Always start screws by hand to avoid cross-threading the plastic mounting points.
