Re: INVERTED PRO NECK: Real Or Real Fake

The triangle symbol could have 2 explanations.  the bolt is a Close Tolerance bolt. or its a specific manufacturer mark. the 3 lines typically means grade 5
of all the pro necks or tuf necks that ive ever owned ive never had one with the triangle

Fake, the sand marks is "popping out" not normal.  I seen some up and down and diagonally, sometimes side to side as well.  Not just one line up and down.

wrong- the triangle you speak of is different then the triangle present on the bolts.

Nick is correct, three radial lines equate to Grade 5, six radial lines equate to grade 8. From what my limited research just found on google, is that the triangle stamp indicates a canadian made fastener/bolt. Please check and or do your own research to confirm or deny this, but I read it, cant confirm it.

Re: INVERTED PRO NECK: Real Or Real Fake

Craig, my research has stated that its just not having a triangle. As the triangle stamps that were the manufacture mark were also located in the center of the bolt and were smaller. But this info is also modern info. This cannot be used to id a 30year old bolt as they were not required to mark the bolts back then. JDB has alot of info on this

Re: INVERTED PRO NECK: Real Or Real Fake

i googled:

http://hotrodhotline.com/md/assets/images/Torquing-MD-10.jpg

Fastener Materials
In addition to the differences in diameter, thread pitch and length, standard and metric fasteners come in different grades.  Standard bolts used in automotive applications come in grades from 0 thru 8.  They are usually identified by slashes radiating out from the center on the head of the bolt.  Grades 0 thru 2 have no slashes on the head, grade 5 has three slashes and grade 8 has six slashes.  Standard nuts have slashes or dots placed around the outside to denote grade.

Bolts on the left are both grade 5 indicated by the three slashes on the head.  The next two are grade 8, one indicated by six slashes on the head, the other by an 8 on the head.  The 8 should not be confused with a metric grade that would be marked with an 8.8 grade indicator.  Bolt on the right has letters on the head but is just a 0 thru grade 4 bolt because it has no slashes on the head.

How about we all post what stampings we have on out stem bolts.
Please state .

tuf neck or pro neck

In og bag or out.
Then the stampings.
Was it scored directly from LBS.
And if youve got the balls. Did you buy it from sunnysgirl(now californiabmxwarehouse) , merbear, 98210sucks, or the guy here that sold like 5 or so right after the above guys stopped selling them

Re: INVERTED PRO NECK: Real Or Real Fake

I strongly suspect this stem is fake BUT not because of the stem bolt.  The 3 or 6 slash marks are common that show a grade 5 or grade 8 bolt.  The additional mark is the mark of the manufacturer of the fastener-also not a tell as they may have gotten stem bolts from different vendors as time went on.

HOWEVER, if you take a look at the allen bolts you will see small stampings on top them-whether they are letters, numbers, or marks that is an indication that those fasteners are NEWER from today.  It is very difficult to get allen bolts with blank tops any more.  I go to an old hardware store that bought out fasteners just to get these type of allen head bolts.  These are NOT available today as I have been told.

I have a NOS Pro Neck from a good friend that pulled it out of a bike shop.  comparing it to the pic I have a strong feeling it is a fake.  I can't be 100% sure as I don't have that stem in my hand BUT the PRO NECK doesn't look right. wink  There is few more "tells" but I will keep that to myself for now until I can prove it.

Now the allen bolts being the wrong kind doesn't 100% prove anything but considering the other hardware is pristine there would be no reason to swap out the old allen bolts for new ones.  Definitely suspect to me based on just this point.

Also the MAJOR issue is that all faces of the stem have the same look-That's all I will say.  wink   I will say that I am 95% sure it's a fake.

Re: INVERTED PRO NECK: Real Or Real Fake

For you to really tell if the Blue stems "Pro Neck" stamp is real you truly need to have it in your hand with a known NOS stem next to it.   I would love to have that blue stem in my hands to compare it my NOS Black std. Pro stem.

KS is what my known NOS stem has Nick and I have 30 year old bolts holding a set of my Profile cranks with the KS on them.  Fastener Mfrs. may not have been required BITD to stamp their product but many did.  That is why you see allens with the stamp today and you never did BITD because it was such a small area to address.

I'll snap some photos of my freshly unwrapped and mounted NOS Pro Neck later and post them up. My stem cap allens have no markings on them but I can't recall about the quill bolts since I'm not near the bike it is mounted on. I'll report back later with some photos.

Re: INVERTED PRO NECK: Real Or Real Fake

This stem is on ebay right now.  Do you notice something about the "PRO NECK" letters vs. the blue stem in question?

Re: INVERTED PRO NECK: Real Or Real Fake

The "O" on the blue suspect pro-neck looks off. And also if you look real close at the round corners of the top cap it looks like there is a tab bit more material, almost as if the cap may be slightly larger or the holes were drilled a little closer to the inside. Breakout the dial calipers and measure it, bolt centering, edge thickness, etc. and see if it matches and original.
