"L19 sounds like a L-series tool steel nothing more.
Almost all tool steels are arc + vacuum remelts.
H11 tool steel is mentioned but defined, wasn't
"cool" enough for the sales staff? LOL

"ARP2000" LOL

Not ARP2 but ARP2000. LOL

Salesmen huh?
Can't trust 'em, can't kill 'em and our industrialized
world would come to a screeching halt without 'em.

Alvin,

Since you have decided you do not like the sales/marketing staff or literature at Automotive Racing Products, and are worried they erroneously renamed a steel just for themselves, ARP2000®: is an exclusive, hybrid-alloy developed to deliver superior strength and better fatigue properties. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving clamp loads in the 215,000-220,000 psi range and is an up-grade from 8740. Whether or not you like ARP is totally up to you, but ARP has a very well earned respect and use in the Professional Automotive & Marine Racing industry simply because there products excel in there specified uses. BTW ARP was founded by Gary Holzapfel in 1968 a weekend racer himself who had many years experience making fasteners for the Aerospace industry prior to launching ARP.

Alvin if they are designated class 12.9 then they are International (SI)
(ie metric), and since they are metric they will be "metric coarse" thread
unless they are specifically stamped "metric fine" thread. There is no North
American Imperial thread (ie standard thread) available on SI bolts.

No as in -never-? :/
Like, never ever? LOL

I've got examples of both ways... grade 5 marked bolts with metric threads
and "8.8 bolts" with 7/16-20 threads.

The latter were used in air cooled VWs for seat belts. No kidding.

If I bought a big enough lot of bolts they would friggin make them however
I wanted them made. Believe it? You never thought of that? :/

-----------------------------

Mister Hat, remember the true/false test questions back in elementary
school how if you saw words like "always", "never" etc the statement was
almost always false? (see how I used the word -almost- there?

Did you not learn that as a child? :/
Don't remember that far back? :/

What about there, their and they're and two, to and too, did you not learn
those either? :/

You are quick to correct others, how quick are you to "here" it back. LOL
