I'm not sure how deep the head stud holes are. I went ahead and bought the Sears 48-pc. set, because it does appear to have most if not all the sizes in common use on the 928. It includes 3 different M10 thread pitches, unlike the ebay set that only has one. I seem to recall there are some less-common thread pitches on our cars, and I figured more is better. Also, I have a Dodge and when I build something from scratch I tend to use US hardware so the US sizes may come in handy.

I was just having a discussion with a mechanic friend about tools, about how with the Craftsman warranty Snap-On has little advantage. I pointed out that there's no way you're going to get a Snap-On tool replaced on a Saturday or Sunday, and he conceded that for that reason alone Craftsman is a better choice for the weekend wrench. OTOH, with more pros going with Mac or Snap-On the risk of someone actually using a tool hard enough to break it may be somewhat reduced for Craftsman.

Back to the head studs -- If they are in fact too deep for the thread chasers mentioned, talk to the guys at olander.com. It's hard to find stuff on their site unless you know the jargon intimately, but they are the first place I would try if I needed an oddball tool like an extra-long thread chaser. Those guys can get just about any hardware imaginable, except for specialized stuff like engine studs. Also, they don't sell self-tapping or wood screws.

Tried to order from them as similar set might not available locally. At leasrt haven't found any. This was result.

Thank you for your order. Unfortunately, due to the ever-increasing complexity of U.S. Export regulations, McMaster-Carr can no longer accept orders for private individuals outside of the United States. We sincerely regret any inconvenience this causes you.

Have to try to find locally something. Snap-on tools is available but their pricing is so high that new block from factory is probably cheaper.

You don't really need an expensive thread chaser, IMHO. I wouldn't go for a cheapo $5 HF set, but the Snap-On price seems a waste.

Taps, OTOH, I'd recommend getting them only as-needed, and go to a reputable local tool supplier -- The kind of place that machinists shop at, like Olander or MSC. MSC, for example, wants $6 for a middle-of-the-road US-made M6x1.0 tap, TiN coated taps start at $9. Buying a large set of this quality would be $$$ and most DIYers would only use a fraction of what's there.

I called a Sears store and the thread chaser is an internet only item. So I just went ahead and bought it, hopefully next week I can post results. I like Brendan want to clean among other things the threads in the block for the head bolts/studs.

I said 40 peice but that was just a round number, the one I saw originally was 48 peice as was the one I ordered. I only saw one "thread chaser" set on the sears site so thats the one I got.

For $50 shipped I dont think you can go wrong.

Ryan,
Let us know if you are happy with it and I will order one as well.
Thanks for the post,

Have it sent to a friend's business, they won't check. The stuff they send to my house is addressed to a company called "Projekt 928" which doesn't exist. The other option is that I could buy another and send it to you for whatever it costs me.

When I bought mine, I was specifically looking for 14x1.5 for the wheels studs since a seperate chaser in that size is generally around $50. Most sets don't have that or 12x1.5, both of which are useful.

SharkSkin

Ryan, they also have a 40 pc set, item 00952105000 which is what I thought you were talking about.

RyanPerrella

huh, i didnt see a 40 peice set, thats odd, cause yes i did say 40

For what it's worth I have had excellent luck buying tools from www.sjdiscounttools.com
They sell name brand tools at very good prices, and their customer service is great.

Got this set in the mail today and I am very happy with it.

A couple things to mention though, 1) the M14 chaser wont fit into the block, stud or head bolt holes. So you will need a longer chaser. 2) What are the files for. They are nice and cool looking but what are they used for?

While we are speaking of thread chasers. What is the proper thread on the bolt that holds the driver's left foot rest to the sidewall?

Porsche, not unusually, uses three bolts with 3 different threads to hold the foot rest on. Being a newbie at that point and crawling around in the footwell, I just dropped them in a cup. When it came time to put 'em back in, I think I buggered up this one.

Looking at chasers which are available locally I think its possible to make these from standard bolts quite easily. Just need some Dremel work to make grooves to streads. This will obviously leave sharp edges. These could be cleaned out with some mild sand plasting for example.

The files are for repairing threads on bolts and just about anything with external threads, you just find the right pitch and they will straighten the threads out. They work quite well on bolts that you have to cut shorter and grind the starting end down with a small taper. you can actually cut new threads with the files.

This is what I was afraid of. Do we have a source for longer skinnier ones?

SharkSkin

They are out there. Try a google search on "long shank" metric tap and you'll get a few good hits, like this and this. That should give you ideas of other keywords to look for.

Or, ask your local machinist(s) where they would go to look for something like this.
