Frequently Asked Questions About Freightliner M2 Business Class Dash Nuts & Screws
What thread sizes and specifications do I need for my M2 Business Class dashboard?
Most Freightliner M2 Business Class dashboards use a combination of metric and standard hardware. The most common sizes are M6x1.0 and M8x1.25 for metric, and 1/4"-20 and 5/16"-18 for standard threads. Dashboard panel screws typically require 15-25mm length, while deeper mounting points may need 30-40mm screws. We recommend checking your specific model year as Freightliner made slight changes between 2003-2007 and 2008+ models.
Are these screws compatible with both steel and plastic dash panels?
Yes, but you'll need different types depending on your panel material. For plastic dash panels, use self-tapping screws with wider thread spacing to prevent cracking. Steel panels work best with machine screws and matching nuts or clip nuts. Many M2 models have a combination of both materials, so we offer hardware kits that include both types to cover all mounting points.
How many screws and nuts do I need for a complete dash removal or installation?
A complete dash assembly typically requires 18-24 screws and 12-16 nuts, depending on your cab configuration and optional equipment. The main instrument cluster uses 6-8 screws, center console requires 8-10, and side panels need 4-6 each. Day cab models generally use fewer fasteners than sleeper configurations. We recommend ordering 10-15% extra hardware to account for any damaged or lost pieces during installation.
What's the difference between OEM and aftermarket dash hardware?
OEM hardware features factory-specific coatings and exact thread pitch matching, while quality aftermarket options use zinc plating or black oxide finishes that meet or exceed original specifications. The main differences are cosmetic - OEM screws may have specific head markings or finishes that match factory appearance. Both options provide the same holding strength when properly torqued to 8-12 ft-lbs for dash applications.
Do I need special tools or washers for installation?
Standard installation requires a T25 or T30 Torx driver for most factory screws, though some locations use Phillips or 10mm hex heads. We strongly recommend using flat washers on all mounting points to distribute load and prevent cracking, especially on plastic panels. Lock washers or thread-locking compound should be used on high-vibration areas like the instrument cluster. A magnetic bit holder helps prevent dropping screws behind the dash during installation.
