Frequently Asked Questions About Freightliner Columbia 112/120 Dash Nuts & Screws
What size nuts and screws do I need for my Columbia dash panel?
Most Freightliner Columbia 112/120 dash panels use #10-24 screws for the main panel attachments and M6 nuts for gauge cluster mounting. The screws typically range from 3/4" to 1-1/4" in length depending on the specific mounting location. For the radio bezel and center console areas, you'll need #8-32 screws. We recommend ordering a variety pack if you're doing a complete dash removal or restoration.
Are these hardware pieces compatible with both Columbia 112 and 120 models?
Yes, the dash mounting hardware is identical for both Columbia 112 and 120 models from 2001 through 2017. The dash panel design and mounting points remained consistent throughout the production run. However, pre-2001 Columbia Century Class models use different hardware specifications, so double-check your model year before ordering.
What's the difference between stainless steel and zinc-plated options?
Stainless steel hardware offers superior corrosion resistance and won't rust even if the finish gets scratched, making it ideal for humid climates or trucks that see frequent washing. Zinc-plated screws are more economical and work well for most applications but may show rust over time if the plating wears off. For visible areas like gauge bezels and switch panels, we recommend stainless steel for longevity and appearance.
How many pieces of hardware do I need for a complete dash removal?
A complete dash removal on a Columbia typically requires approximately 35-45 pieces of hardware: 12-15 screws for the main dash panel, 8-10 for the instrument cluster, 6-8 for the center console area, 4-6 for the glove box, and various nuts for switches and accessories. We offer complete hardware kits that include extras to account for lost or damaged pieces during removal.
Do you carry the plastic retainer clips that break during dash removal?
Yes, we stock the plastic push-pin retainers and trim clips that commonly break when removing Columbia dash panels. These include the white nylon Christmas tree clips for the lower dash panels, black push-pins for the defroster vents, and the spring-loaded retainers for the side panels. Since these are prone to breaking, we recommend ordering extras to have on hand for future maintenance.
