cota kid Posted August 4, 2006 Report Share Posted August 4, 2006 Similar problem on my Sherco and more recently my 4RT. Replaced them with 315 hex headed bolts. Quote Link to comment Share on other sites More sharing options...
copemech Posted August 14, 2006 Report Share Posted August 14, 2006 I will only say that if you spend an ounce of prevention it is worth a pound of cure! Coat the threads of all your common bolts with a mix of anti-sieze and good grease and you will never have a problem! Even the 4RT will corrode like a pig if you do not protect it from the mud and water entry! Those Jap bolts are the worst when it happens!

gii Posted August 19, 2006 Report Share Posted August 19, 2006 Crap fastenings (Japanese, Spanish or Italian) are the bane of our lives. Good quality bolts are still very cheap and are available in a variety of materials and coatings. I buy M5 and M6 socket heads (Allen) and button heads 50 at a time 25mm long in A2 stainless, they don't cost so much and you can easily cut them down. BUT Dont Ever use Stainless bolts to mount calipers or discs. Buy HT Steel, yellow passivated or galvanised if you can find them, and coat them with copperslip or waxoyl Quote Link to comment Share on other sites More sharing options...

neonsurge Posted September 14, 2006 Report Share Posted September 14, 2006 BUTDont Ever use Stainless bolts to mount calipers or discs. Why? I replaced the caliper bolts on my old Beta with cap head stainless ones and never had a problem. Not being snarky, I'd like to know for future reference...

dale Posted September 14, 2006 Report Share Posted September 14, 2006 Hi, i was told that stainless bolt have less tensile strength than mild steel and are more prone to shear Quote Link to comment Share on other sites More sharing options...
barrybaines Posted September 14, 2006 Report Share Posted September 14, 2006 Hi, i was told that stainless bolt have less tensile strength than mild steel and are more prone to shear Correct if using Stainless in high stress areas you MAY have problems but I beleive differnt grades are available for such instances, this is where Ti is worth considering as the higher grade stainless may be about the same cost or not much in it and Ti is obviously lighter and a bit more bling Quote Link to comment Share on other sites More sharing options...
