Common QuestionsFAQ

Do I need a rivet nut tool to install this kit?

Only if you're using the rivet nuts for a blind install. If your panel is already through-hole, you can mount directly with the included nylon lock nuts — no extra tools required.

Where can I install these bolts?

Common applications include engine bay covers, exterior trim, bumpers, fender flares, widebody kits, and custom brackets with M8 thread points. Always confirm thread size, pitch, and length before installing.

How do I maintain the PVD finish?

Clean with a mild, pH-balanced solution and avoid abrasive cleaners. Re-check torque after heat cycles, especially in engine bay locations.

Flawless machine work, perfect GOLD finish, threads true to size works of art

Goooollllldddddd, love the gold finish on these works of art. (seriously)First thing that stands out with this kit is the build quality. The bolts are titanium grade 5 and you can tell right away they aren’t your average hardware store special. The machining is crisp and clean, no rough edges or sloppy cuts, and the button heads have a nice wide contact surface that sits flush without chewing up the panel. The gold finish looks incredible in person, almost like jewelry for the car. It catches light in a way that makes the engine bay look way more high end without being over the topUsing them was pretty straightforward. The kit comes with everything you need right down to the little rubber spacers and the hex key(I still wrapped in plastic to protect that GOLD!), so there’s no running back and forth looking for missing pieces. The rivet nuts went in smooth and the lock nuts thread on nicely without binding. I didn’t have to fight with them or worry about stripping, which is always a relief when you’re bolting into something that you only want to do onceFitment was spot on. The M8 threads matched perfectly with existing mounting points and the wider heads give a really solid grip on panels and brackets. They’re lightweight but feel extremely sturdy once installed, and nothing rattles or shifts around after tightening. Even under heat and vibration in the engine bay they’ve stayed snug and quiet, which tells me they’ll last a long time without backing offFor the price you’re paying you get a premium set that not only does the job but also upgrades the look of the car. Regular bolts hold things together, but these look like they belong on a show car while still being tough enough for daily use. Feels like a bit of overkill in the best possible way, and definitely worth it if you like mixing function with style
