Q: What wrench or socket size should I use?
A: Use a wrench or socket sized for 5/16 in. hex bolt heads; check your tool set for the matching SAE size.


Q: Are these bolts suitable for outdoor use?
A: The zinc-plated finish offers moderate corrosion resistance for indoor and light outdoor applications; for harsh environments, consider galvanized or stainless steel.


Q: What nuts should I pair with these bolts?
A: Use 5/16-18 coarse-thread nuts and matching washers to ensure proper fit and load distribution.


Q: Is drilling required before installation?
A: Install into appropriately sized pre-drilled holes or tapped threads; ensure the hole matches 5/16-18 coarse thread specifications.

A Must Have For Car Restorations!
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
I have been installing this matting in my 74 Datsun 260Z restore and very pleased with the ease of application and overall quality. My car has bedliner coating inside and this stuff sticks extremely well and is easy to trim and shape as well. I have just started installing it and using the rollers to work it in place but I can already tell a difference with just the little bit I have added....has reduced the resonance in the metal already. It's not a fast process but know it will be very rewarding once complete.

Easy to apply
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
Nice product. With adhesive applied, this an all in one product. Easily cut to random shapes and dimensions and the adhesive seems to hold well. Removing the paper that protects the adhesive to apply in tight areas, presents a new set of problems. Having applied the product inside the panels of an old Trooper, it is yet to be determine if sound and temperature transfer are reduced.
