The ARP 1/2-13 x 3.250 12‑point stainless steel bolt is a single 12‑point fastener sized to 1/2‑13 threads with a 3.250-inch length. Intended for use as a replacement or repair fastener in fabrication and assembly, it works with standard 12‑point sockets and provides the stainless look expected where a longer 12‑point stainless bolt is needed for through‑bolting or visible connections.
