Bolt Kit - 12pt. (5) 6mm x 1.00 x 30mm

The Bolt Kit - 12pt. (5) 6mm x 1.00 x 30mm by ARP delivers premium fastening solutions for high-performance engine builds and critical automotive applications where reliability is non-negotiable. Whether you're assembling a stroker motor, upgrading cylinder head fasteners, or reinforcing valve cover bolts on a turbocharged platform, these ARP bolts provide the clamping force and tensile strength required for sustained power delivery. This five-piece kit is an essential upgrade for builders and mechanics who refuse to compromise on fastener quality when every component matters.

ARP's 12-point bolt design offers multiple engagement angles that reduce the risk of rounding compared to traditional six-point fasteners, making installation cleaner and more forgiving under shop conditions. The 6mm diameter with a 1.00mm pitch thread provides optimal load distribution in metric engine applications, while the 30mm length accommodates most OEM and aftermarket component specifications. ARP's proprietary heat-treatment and alloy composition ensure consistent tensile strength and superior corrosion resistance, critical for engines exposed to high combustion temperatures, fuel exposure, and extended service intervals. The compact 0.12 lb weight profile keeps assembly mass minimal while delivering measurable structural integrity gains.

This bolt kit is ideal for import tuners, domestic performance builders, and professional mechanics standardizing on ARP fasteners across metric engine platforms—including Japanese, European, and other metric-threaded applications. Installation requires proper torque specifications (consult ARP's technical data or engine builder guidelines for your specific application) and a quality torque wrench to achieve repeatable clamping loads. The five-piece quantity suits valve cover assemblies, thermostat housings, fuel rail brackets, and accessory mount points where critical fastening integrity prevents leaks, vibration loosening, and component failure during high-RPM operation or boost application.
