ARP 621-4000 Gaskets & Seals

These gorgeous bolts are rated at 170000 psi to provide a substantial extra margin of safety over grade 8 and other hardware. They can be used on cars as well as boats and trailers. Stock up on these truly maintenance free bolts so you have them when the need arises.

Standard Hex Bolt

Now you can use premium quality ARP stainless steel or chrome moly fasteners to install most anything on a car, boat or trailer. The specially alloyed ARP 300 stainless steel and heat-treated 8740 chrome moly bolts (black oxide finish) are nominally rated at 180,000 psi tensile strength to provide a substantial extra margin of safety over Grade 8 hardware.

Whats more, you cant beat the gorgeous looks of ARPs specially polished stainless steel fasteners, and their ability to resist rust. Theyre truly maintenance free!

You can get 5-packs (washers included) of any diameter bolt from 1/4 to 1/2 or M6 to M12 in lengths ranging from 1/2 to 6, with ARP12-point heads. Matching nuts are also available

I like this site has very low prices and great products

Found my fender flares easy made payment and shipped right away received my product in 2 days gr8 seller will do business again

I ordered new leaf springs for my Jeep Cherokee. Its already headed out to me. Ordering was nice and easy. I'll post more once i get it.

It was easy and the price is good, but this is just the order. If I get the product in the same manor, that will be great. Thanks, Mike

Good experience...autoplicity had the most competitive prices for both my jk wrangler daystar dash panel and a smitybilt inclinometer...would have likes shipping to be a little quicker, but overall good
