Frequently Asked Questions About Peterbilt 330/335/337 Dash Nuts & Screws

What size dash screws and nuts fit my Peterbilt 330, 335, or 337?

Most Peterbilt 330, 335, and 337 models from 2005-2015 use #10-24 screws for dash panel mounting and M6 metric nuts for gauge clusters and switch panels. Interior trim pieces typically require #8-32 screws. We recommend checking your specific year model as Peterbilt made minor changes in 2016+ models that may require different fastener sizes. Always verify thread pitch before ordering to avoid cross-threading.

Are these dash fasteners stainless steel or regular steel?

We carry both stainless steel and zinc-plated steel options. Stainless steel fasteners resist corrosion better and won't rust over time, making them ideal for humid climates or trucks with cab leaks. Zinc-plated steel fasteners cost less and work well for most applications but may show rust after 3-5 years. For dash components exposed to moisture or frequent cleaning, we recommend stainless steel.

Will these screws work with aftermarket dash panels and gauges?

Our standard dash screws work with most aftermarket panels that maintain OEM mounting hole specifications. However, some aftermarket gauge pods and custom dash panels require different thread patterns or lengths. Measure your mounting hole depth and check if you need standard 3/4" length screws or longer 1" screws for thicker aftermarket panels. Contact us with your specific aftermarket brand for compatibility confirmation.

Do I need special tools to install these dash fasteners?

Standard installation requires a Phillips head screwdriver for most dash screws and a 10mm socket or wrench for nuts. Some locations behind the dash require a magnetic screwdriver or extension to reach tight spaces. Avoid power tools during installation as overtightening can strip threads or crack plastic dash components. Hand-tighten until snug, then add an extra quarter turn.

How many fasteners do I need for a complete dash refresh?

A typical Peterbilt 330/335/337 dash assembly uses approximately 40-50 screws and 20-25 nuts total. This includes gauge cluster mounting (8-10 screws), switch panels (6-8 screws each), dash trim pieces (15-20 screws), and radio/HVAC mounting (10-12 screws). We offer complete fastener kits that include extras for commonly lost pieces, or you can order specific quantities based on your repair needs.
