Frequently Asked Questions About Kenworth T680 Dash Nuts & Screws

What thread sizes and specifications do I need for my T680 dash panel?

Most Kenworth T680 dash panels use a combination of M6x1.0 and M8x1.25 metric threads, along with some standard 1/4"-20 and 5/16"-18 fasteners for specific components. The gauge cluster typically requires M6 screws, while heavier components like the center console use M8 fasteners. We recommend checking your specific model year as Kenworth made minor changes between 2013-2020 models. Our product descriptions include exact thread specifications for each fastener.

Are these fasteners made from stainless steel or will they rust over time?

We carry both stainless steel and zinc-plated options for T680 dash hardware. Stainless steel fasteners (typically 304 or 316 grade) offer superior corrosion resistance and are ideal for humid environments or trucks that experience frequent cab washing. Zinc-plated fasteners provide good corrosion protection at a lower cost and are suitable for most applications. Each product listing clearly states the material composition and finish type.

Do I need special tools to remove and install dash fasteners without damaging the plastic?

Yes, using the right tools prevents costly damage to your dash panels. We recommend using plastic trim removal tools for clips and a magnetic-tip screwdriver for screws to avoid dropping them behind panels. For torque-sensitive areas like the instrument cluster, use a torque screwdriver set to 15-20 inch-pounds to prevent cracking. Many installers also find a 90-degree pick tool helpful for accessing recessed screws near the windshield area.

Will aftermarket dash screws affect my warranty or cause fitment issues?

Quality aftermarket fasteners that match OEM specifications will not affect your warranty when used for routine maintenance or repairs. Our dash hardware meets or exceeds Kenworth specifications for thread pitch, length, and head style. However, ensure you're selecting the correct length - using screws that are too long can damage wiring harnesses or HVAC components behind the dash. Each product includes detailed measurements to ensure proper fitment.

How many fasteners do I need for a complete dash removal or installation?

A complete T680 dash assembly typically requires 45-60 fasteners depending on your specific configuration and options. The main instrument panel uses approximately 12-16 screws, the center console requires 8-10, and various trim pieces account for the remainder. We offer complete hardware kits that include all necessary fasteners for full dash service, or you can purchase specific quantities for partial repairs. Consider ordering 10-15% extra as these small parts are easily lost during disassembly.
