Frequently Asked Questions About International RH Dash Nuts & Screws

What are the exact thread sizes and lengths for International ProStar and LoneStar dash panel screws?

Most International ProStar (2008-2017) and LoneStar (2009-2017) models use M6 x 1.0 thread pitch screws for dash panels, with lengths varying from 16mm to 25mm depending on the specific mounting location. The center dash panels typically require 20mm screws, while side panels often use 16mm. Always verify your specific model year as International made minor changes throughout production runs. We recommend ordering a variety pack if you're doing a complete dash restoration.

Are these hardware pieces stainless steel or zinc-plated, and which is better for preventing rust?

We carry both stainless steel and zinc-plated options. Stainless steel (typically 304 grade) offers superior long-term corrosion resistance and won't show rust even if scratched during installation. Zinc-plated screws are more economical and work well for interior applications but may develop surface corrosion over time if the plating is damaged. For dash applications where moisture exposure is minimal, zinc-plated hardware is usually sufficient, but drivers in humid climates or those who frequently wash their cab interiors often prefer stainless steel.

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

Yes, using the right tools prevents costly damage to dash panels. For push-type retainers, use a proper trim removal tool set with forked ends rather than screwdrivers. For threaded screws, a magnetic tip driver helps prevent dropping screws behind the dash. Many International dash screws use Torx heads (typically T20 or T25), so have these bits ready. Apply gentle pressure and work slowly - International dash plastics become brittle with age and crack easily if forced.

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

A complete International ProStar or LoneStar dash typically requires 35-45 fasteners total, including approximately 20-25 screws, 10-12 push clips, and 4-6 specialty retainers for items like the gauge cluster. Numbers vary slightly between model years and trim levels. We recommend ordering 20% extra as International dash fasteners are prone to breaking during removal, especially on trucks over 5 years old. Consider our complete hardware kits which include all necessary pieces plus spares.

Will aftermarket screws fit properly, or do I need OEM International parts for proper fitment?

Quality aftermarket screws that match OEM specifications work perfectly fine and often cost 50-70% less than dealer parts. The key is ensuring correct thread pitch, length, and head style. Avoid hardware store substitutes as they rarely match the exact specifications needed. Our aftermarket options are manufactured to OEM tolerances and include the correct shoulder designs and thread patterns specific to International applications. Many customers report our parts fit better than some recent OEM batches.
