Construction & Design

The ARP 12pt Hardware Kit features nuts crafted from aerospace-grade steel, ensuring maximum strength and durability. The black oxide coating not only provides a sleek, professional appearance but also offers excellent corrosion resistance, extending the lifespan of the hardware in harsh environments. The 12-point head design allows for increased wrench engagement, which is especially beneficial in tight or hard-to-reach areas, reducing the risk of damaging the fastener during installation or removal.

Designed with precision machining, these nuts maintain tight tolerances for a perfect fit on standard 5/16˝-18 threaded bolts. The absence of nylon inserts or self-locking features means these nuts rely solely on their high tensile strength and proper torque to maintain secure fastening, making them suitable for applications where a reliable, vibration-resistant connection is critical.

Installation & Fitment

The ARP 12pt Hardware Kit is designed for easy, straightforward installation. These nuts are compatible with standard 5/16˝-18 threaded bolts and can be installed using common hand tools. No special tools or procedures are required, and the nuts can be tightened to the manufacturer's recommended torque specifications for optimal holding power. Their design allows for quick removal and reinstallation if needed, making maintenance or adjustments hassle-free.

Because these nuts do not feature self-locking mechanisms, it is important to ensure proper torque application during installation to prevent loosening due to vibration. For critical applications, consider using thread-locking compounds or lock washers as needed.
