ARP 644-2000 5-Piece Bolt Kit – 3/8-16 Thread, 2.000 Inch Length, 12-Point Head, Chromoly Black Oxide

Need some seriously strong bolts for engine work, suspension, or any high-stress application? This ARP kit is exactly that. You get five bolts, each measuring 3/8-16 thread and 2.000 inches long under the head. They have a 7/16-inch 12-point head, which gives you more grip and torque options than a standard hex head.

They're made from chromoly steel and have a black oxide finish for a bit of corrosion resistance and a clean, low-glare look. ARP is the go-to brand for performance fasteners, so you know these are built to handle serious clamping force without stretching or snapping. Perfect for automotive racing, machining, or any project where a standard hardware store bolt just won't cut it. Keep your builds secure with proven quality.
