Product Details

ARP 400-8031 Lug Nuts, Studs & Locks

Stainless Accessory Studs
16Pieces

ARP has developed an innovative multi-purposes accessory stud that can be used for exhaust systems, intake manifold and a host of other uses. The studs are manufactured from a proprietary alloy developed by ARP (Stainless 300) and are impervious to the rust and corrosion that plagues ordinary fasteners. This stainless steel alloy is nominally rated at 170,000 psi tensile strength, which is substantially stronger than Grade 8 hardware. Ideally suited for installing exhaust headers, the 8mm studs have a unique nut starter nose and a hex-broached tip which allows the studs to easily be installed using an Allen wrench. The studs come with easy wrenching 12-point nuts, which work great in the tightest of quarters. Flat washers are also included.
Offered in five different lengths, in quantities of 4, 8, 10 and 16-packs.

Great prices. Hope to deal again..;)

I am so pleased! Autoplicity had the best price by far for the item I ordered. I was not familiar with them so having the Paypal option was perfect. Over all I saved $30 on an item that was close to $100. Shipping was VERY reasonable and quick. I ordered my item on Saturday. They shipped it right away and I received it on Wednesday. I am definitely an Autoplicity fan and will recommend them to my friends not to mention our mechanic. He found the item I wanted on sale through another major company. Just to double check, I searched online and Autoplicity blew that company out of the water with their pricing and service for the exact same item. Very nice!

I ordered a WeatherTech cargo liner from Autoplicity after finding the product almost $40 cheaper than anywhere else. Usually I'm suspect of the one company with a very low price but the high number of reviews gave me enough comfort to order. The product came in a large box and was shipped for a very reasonable price and arrived in four business days. The product is as described and I couldn't be happier. I will definately keep them in mind for future orders.

Excellent prices and quick shipping. Will definitely use again.

Awesome Products!

Fantastic prices and fast shipping!! Looks like I'm done with Jeg's and Summit!!

I am very pleased with my purchase from Autoplicity. Price was very reasonable and shipping was great!
