Product Details

The ARP APN12-6A is a high-performance 7/16-20 thread 12-point nut manufactured from ARP's proprietary Custom Age 625+ super alloy material. Designed for extreme performance applications, this premium fastener delivers exceptional strength and reliability in the most demanding racing and performance environments.

Key Features:

  • Custom Age 625+ super alloy material with 260,000-280,000 psi tensile strength
  • 7/16-20 thread pitch for precise fitment
  • 12-point design provides superior socket clearance in tight spaces
  • Complete resistance to atmospheric corrosion and oxidation
  • Superior fatigue cycle life compared to standard fastener materials
  • Heat-treated prior to thread rolling for maximum strength
  • Centerless ground for perfect concentricity

ARP's CA625+ material represents the pinnacle of fastener technology, offering strength comparable to L19 material without the handling challenges. This super alloy is ideal for high-boost forced induction applications, endurance racing, marine environments, and any application where extreme cylinder pressure, severe thermal cycling, or corrosion resistance is critical. Each nut is manufactured to exacting aerospace-quality standards, ensuring consistent performance and reliability when it matters most.

Good stuff

Ordered a Thule ski rack. Best price on the web. Prompt delivery as promised, however, did not get shipping email and tracking no until after delivery was already made. The customer service that I experienced trying to get info on delivery was less than desirable. Four stars o ly.

shopped around , bought at autoplicity !

Fast shipping , product just as described, and quality product.

the amazon payment did not work; hope I don't get double billed since I went with paypal afterwards. Meanwhile, I could not verify that my amazon order is cancelled/never placed.

smooth checkout/shopping cart
