Top quailty and great ability to tighten in closed area ... would buy over nd over. I had bought 12 point stainless bolts and used them every where on my engine however on the headers we had 2 spots that these heads were they only one's that would work. Beautiful product

Exactly what I needed to install some tight fitting headers on my small block chevy V8. These are genuine ARP parts and the part number and bolts are exactly as described. I always use Nord-Lock stainless steel lock washer on header bolts an have never had one come loose. The washer that come with these are top quality so will find another use for them.

Used these for a 5.0 302 header install that had tight fit getting a socket on the bolt head next to a bunch of the runners, to these small bolt heads made it perfect since I could use a much much smaller socket.No problems torquing enough or stripping due to the small head, the stainless is very hard and they worked perfect for a tight header install on a 5.0 mustang.

These header bolts make it a lot easier to tighten down or loosen up. I can actually get a box end wrench on them

Needed the smaller 5/16†size bolt head, was not able to get a wrench on 3/8†heads bolts. The chambers on my headers were to big. A little pricey but my exhaust leaks are gone.

Top of the line products from ARP. Used these to hold the turbo manifolds securely to the heads of my Twin Turbo Fox Body

These header bolts have a 5/16 hex head. it makes for lots of clearance when tightening the bolts up.Great product.
