Construction & Design

The ARP 12pt Hardware Kit is constructed from ARP's proprietary 450 stainless steel, known for its exceptional strength and corrosion resistance. The fasteners feature a flanged, 12-point head design, which provides increased grip and accessibility when tightening or loosening in confined spaces. The smaller diameter heads are specifically designed to improve clearance around the starter area, making installation and maintenance more straightforward.

The polished finish not only adds a sleek look but also acts as a protective barrier against rust and corrosion, ensuring the hardware maintains its integrity over time. The precise manufacturing process, including CNC machining and meticulous quality control, guarantees consistent thread engagement and fitment, critical for high-stress applications.
