Product Details

Constructed from aerospace-quality materials, these fasteners deliver exceptional strength and reliability in demanding cylinder head installations.

Key Features:

  • Aerospace-quality material construction for maximum durability
  • 180,000 PSI tensile strength rating for extreme clamping force
  • Black oxide finish provides corrosion resistance and professional appearance
  • Fine thread design for precise torque control and optimal load distribution
  • Manufactured to ARP's stringent quality control standards
  • Set includes 5 hex nuts

ARP fasteners are the industry standard for serious engine builders who demand absolute reliability. The black oxide coating not only protects against corrosion but also provides improved lubricity characteristics during installation. Fine thread fasteners offer superior clamping force and are less prone to vibration loosening compared to coarse thread alternatives.

I ordered an exhaust setup (headers and a cat-back) late monday night, an it was shipped on wednesday. Thanks for a fast transaction Autoplicity!

Ordered monroe struts and shocks best price I could find. Will order again from Autoplicity when I need something else for one of my cars.

Great price, and quick processing of my order. Will use again.

Fast and easy

Excellent Service! Product shipped out the day after being processed and was sent via overnight delivery. Autoplicity also offered the lowest cost available for the product online.

Autoplicity is a great merchant to do business with. They stock a wide variety of high performance parts at rock-bottom prices, and they ship quickly without any hassles. They are a pleasure to deal with.

By the time you add in shipping, even the "Rock" can't compare! Thanks!

After shopping around for a specific cargo carrier, Autoplicity had the best total price by over $50 and great ratings, so I gave them a try. I received the SportRack Aero XL - A90275 last Thursday and am VERY impressed with their price and service. The cargo carrier arrived quickly (ordered Sat, rec'd Thurs) and in fine shape. I will recommend Autoplicity to my friends, and plan to shop with them for my future automotive needs.

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.

Ordered a K&N cold air intake for my 2010 ford focus in hopes to add a little horsepower and mpg. Well, autoplicity has great customer service and my part arrived exactly when it was supposed to. Very pleased with autoplicity, will be going back for my future purchases, you can't beat their prices and service!
