disc bolts snapped

[Deviant400]

ok so thought id threadlock my disc bolts , upon tightning them up ive snapped one , god knows how, didnt think id put that much force on it , so whats the best method for removing it , not much thread showing if any, and ive had enough for today so by this time tomoz the locker will have gone off, (its non permanent of course)

[micpec]

if there is little thread left, maybe a small locking tool plier can be used to get the remaining thread out?

You could try warming it up with a blow torch, will help melt the thread lock and cut a slot in and use an impact driver to get it out, or weld a nut on, tho i've never tried this.

been there done that - or should i say i purchased a wheel and disks (from someone who shall remain nameless) with one disk bolt snapped off, to be ground down a tad and glued back on - yes glued

Some quality stud extractors, heat to expand the alloy a bit, and slowly drill the centre out and use a stud extractor again with some local heat on the alloy - and out it comes.

sighs, yea my own stupid fault just now im thinking ill replace the lot now as there a bit old and the chances are ive overtightened the bloody lot so as soon as i wang the anchors on pop pop pop go the heads then certain death ,
my question is ... new disc bolts from david silver comes to about £30 odd quid but stainless from pro bolt are like £60+ , but bolt me up do allen cap bolts in a2 stainless for a fraction , anyone used them ??

"edit" i mean is there somthing special about disc bolts that i need to know like are they super hardened or owt

5 bolts will do....

if anything mate they tend to be a softer metal, so a lower tensile strenght like 8.8 or 10.9, allowing them to flex . thats why they can easily be over tightend as the 8 and 9 reffure to the max %...so 80% and 90% they should be torqed too so the bolt is working at its strongest. thats why these bolts should never be reused once torqed then removed.

iv never used stainless on any parts that need this slight flex to accure, such as the disc bolts,caliper bolts, sprocket bolts etc......although pro bolt wouldnt sell them if they wernt safe, but you should deffo use a locking agent like loctite or thread wire them together.

What is this 8.8 or 10.9 you are talking about? Last time I checked tensile strength was measured in MPa and stainless steel is 500+
