TexasQuest Posted May 31, 2014 Report Share Posted May 31, 2014 (edited) Any recommended place to get metric 10x1.25 studs? Got a stud that fell out of the head on the exhaust side, and the hole is too large to replace with another 8mm oem stud. Anyone use these? http://www.ebay.com/itm/10-M10-1-50-M-8-1-25-x-38mm-Double-End-Step-Studs-Steel-Plain-/121342282319?pt=Motors_Car_Truck_Parts_Accessories&hash=item1c40904a4f&vxp=mtr Edited May 31, 2014 by TexasQuest Link to comment Share on other sites More sharing options...
natallica Posted May 31, 2014 Report Share Posted May 31, 2014 (edited) I used a Helicoil kit on an older head and it seemed to work well, think I grabbed it at Autozone.It works as a solution but probably not AS permanent as re-tapping and using a larger diameter stud. Just a thought. -N8 Edited May 31, 2014 by natallica Link to comment Share on other sites More sharing options...
TexasQuest Posted May 31, 2014 Author Report Share Posted May 31, 2014 I've got a helicoil kit to rethread to 10mm. Just need a good recommended stud (if there is some) other than whats on ebay. Link to comment Share on other sites More sharing options...

techboy Posted May 31, 2014 Report Share Posted May 31, 2014 I've ordered stuff from McMaster that BC_99 recommended above. They always have good stuff. Usually if I'm in a bind for odd hardware I swing in the local Fastenal and see what they can do. Usually they can order just about anything.

Skullzaflare Posted May 31, 2014 Report Share Posted May 31, 2014 i had a set of head bolts for a 00 4 cyl camry, i cut the ends off and made studs with them, never had any issues. they are 10x1.25 Link to comment Share on other sites More sharing options...
vbrad511 Posted May 31, 2014 Report Share Posted May 31, 2014 Another thing to think about, they don't just fall out. There's a reason they've stripped and rounded. Wouldn't hurt to stress-relieve your manifold, and make sure the weight of your exhaust is supported front to back. Link to comment Share on other sites More sharing options...
TexasQuest Posted May 31, 2014 Author Report Share Posted May 31, 2014 I installed a K D M exhaust without welding in a flex section, that was probably the culprit. I've since then got a flexpipe installed, just need to fix that bolt that wiggled out. Link to comment Share on other sites More sharing options...
importwarrior Posted June 1, 2014 Report Share Posted June 1, 2014 I had the same problem. The funk lock helps a lot. I also had the muffler shop support the entire exhaust with no weight on the turbo down pipe. I can unbolt the down pipe and the bolt holes for the down pipe flange are basically centered on the studs. No weight on the turbo. I do have a flex section now too.

markhansenconquest Posted June 3, 2014 Report Share Posted June 3, 2014 (edited) Here s how I do it....I make it 3/8 -16 threads .. Get 8 long set screws made out of 4130 chrome moly steel( heat treated) ( mac master car 1.75 long ).... ..Why does it have to be metric ?? The stripped out hole is .305 to .315...A .3125 dia drill is the tap drill for 3/8-16 dia threads....So I use the manifold as a drill jig...Use the 2 farthest studs and tighten 2 nut on...Open top 3 holes of manifold to .3125 dia and 1/8 deeper in head,witch will be .750 deep from face of manifold....Tap those 3 holes ....(bottom tap too if u have a bottom tap)....Try to get .625 depth threads..Put in 3 long set screws and tighten up with nuts on....Then u only have to remove the nuts from the first 2 and do the same to the bottom 3 holes and back to the first 2 that u started with.. In the bottom 3 holes u wont be able to use manifold as a driil jig make sure u drill straight and tap straight !!!!!!!! or manifold will have trouble fitting on....get 3/8 -16 exhast nuts with hardened washers at pep boys... Next u have to open holes in the manifold and gasket to .406 dia ,So that there is .015 thousands clearance on each side of set screw studs to let it move when hot!!!!!! .(holes in manifold are .390 dia and .350 on center holes to aline manifold on head ...u can open all holes to .406 dia or only open the center holes to .390 dia and the rest to .406 dia.

questsale Posted June 3, 2014 Report Share Posted June 3, 2014 Convert those puny M8 studs to M10, and use Toyota studs and nuts. Much better steel, much better quality. Link to comment Share on other sites More sharing options...

boostintsi Posted July 28, 2014 Report Share Posted July 28, 2014 Www . belmetric.com. I use these guys for a lot of automotive hardware. We order from them often and always good quality and pretty quick shipment. If you get your order in before 2 or 3 it's same day shipping. Link to comment Share on other sites More sharing options...
