ARP Body Fastener Kit
Why ARP Body Fastener Kits Stand Apart
When it comes to holding a vehicle together, the fasteners doing the work matter far more than most builders realize. ARP (Automotive Racing Products) has been setting the standard for high-performance fastener engineering since 1968, and that same race-proven philosophy carries directly into their body fastener kits. Whether you're restoring a show car, building a dedicated track machine, or refreshing a daily driver's body hardware, ARP brings a level of metallurgical expertise to body fasteners that generic hardware-store bolts simply cannot match.
Race-Proven Materials, Street-Ready Results
ARP's body fastener kits are offered in two primary premium material families that reflect the brand's engineering depth. Heat-treated 8740 Chromoly steel fasteners feature a black oxide finish and deliver serious tensile strength in a functional, understated appearance — the choice of builders who prioritize performance and corrosion resistance in demanding environments. For enthusiasts who want a show-quality finish under the hood or on exposed body panels, ARP's Stainless 300 alloy fasteners provide a brilliant, rust-resistant surface that holds up to the elements without sacrificing strength.
What sets ARP apart from commodity fasteners is the material selection process itself. While 8740 Chromoly steel comes in four different grades, ARP uses only the top two — SDF and CHQ — which cost twice as much as lower commercial grades but deliver zero-defect quality you can trust every time. Every fastener in an ARP body kit is held to those same uncompromising standards.
Everything You Need, Organized in One Kit
ARP body fastener kits are designed with the builder's workflow in mind. Virtually everything you need comes completely organized in one convenient package, eliminating the need to deal with multiple separate part numbers. Each kit is vehicle-specific or application-specific, so builders can trust that thread pitch, length, and head style are already sorted — no guesswork, no mismatched hardware.
ARP offers both hex head and 12-point head configurations depending on the application, giving builders the flexibility to choose the right tool engagement for their installation environment. The 12-point design allows for better wrench access in tight body panel areas, while hex heads provide straightforward installation with standard tools.
Built on Aerospace-Level Quality Control
ARP was the first company to design, engineer, and manufacture fasteners specifically for racing applications, and has developed many patented processes for manufacturing high-strength fasteners from premium-grade materials. That innovation extends across every product line — including body hardware. ARP has achieved ISO 9001 and AS9100 registration, certifications that represent the brand's unwavering dedication to producing the highest-quality fasteners available.
All ARP fasteners are proudly made in the USA to the industry's highest standards. For body fastener kits specifically, that means every bolt, stud, and nut in the package has passed through the same rigorous in-house quality process that supplies fasteners to NASCAR, IndyCar, and NHRA teams.
The Right Choice for Restorations, Builds, and Track Cars
Upgrading to ARP body fastener kits is a particularly smart move during frame-off restorations, body panel replacements, or any project where OEM hardware has corroded or fatigued over time. The kits replace weak factory hardware with fasteners that are superior in strength to OEM bolts and significantly better than hardware grades — even Grade 8. For show cars and modified street builds alike, the consistent finish and matched hardware of an ARP kit elevates the overall quality of any build.
