I work in a company producing high strength screws for the automotive industry, we are leading supplier for predominantly german vehicle manufacturers. After getting my arp head studs, I had them tested in the lab of our company for their quality. The spectral analysis showed that it is as promised a very high quality material / alloy. And the tensile strength was 14.9. The bolt was also very dimensionally stable and had close tolerances. So this is a very high quality and definitely better product than a mass production product and thus justifies the pretty high price. So I do not have to mention that they let themselves be installed perfectly.

Pretty cool mod

Pretty good mod if youâ€™re replacing head bolts, or even after removing cylinder head if havenâ€™t done so.
