Product Details

ARP's multi-purpose stainless steel accessory studs are engineered for exhaust systems, intake manifolds, and various high-performance applications. Manufactured from ARP's proprietary Stainless 300 alloy, these fasteners deliver exceptional corrosion resistance and durability in harsh environments.

Key Features:

  • Stainless 300 alloy construction with 170,000 psi tensile strength—stronger than Grade 8 hardware
  • 8mm diameter studs with unique nut starter nose for easy alignment
  • Hex-broached tip allows installation with Allen wrench
  • 12-point nuts included for superior wrenchability in tight spaces
  • Flat washers included for proper load distribution
  • Impervious to rust and corrosion that degrades standard fasteners

This 8-piece kit is ideal for header installation and other demanding fastening applications where strength and corrosion resistance are critical. The hex-broached design simplifies installation, while the high-strength stainless alloy ensures reliable clamping force in extreme temperatures.

Haven't installed the parts but am impressed with speed of delivery and quick shipping.

So far so good. Lets make sure this is the right part.

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

Lowest price on EBC brakes for my Subaru. Good speed on processing.

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Great product! Don't even think about another battery hold down - this one is strong, light and has the good looks to boot. Saved over $30 on it too.
