kinell Posted April 17, 2005 Report Share Posted April 17, 2005 Can anybody explain how bolts are measured? I want to get rid of the 5 phillips bolts on the rear mudguard and the 3 phillips head bolts that hold the middle box and rear silencer on (05 Beta). I want to order them online and don't want to end up with the wrong ones being delivered. Obviously, bolts/screws come with different head types: - hex, allen, phillips, slot etc. Length of bolt isn't a problem as I can measure the original ones. I'm struggling to find out the bolt diameter and thread type Any suggestions? Cheers Quote Link to comment Share on other sites More sharing options...
the artist formerly known as ish Posted April 17, 2005 Report Share Posted April 17, 2005 thred pitch, pitch em in't bin and take up line dancing Or you could just see who does the colored bolts sets in alloy, gold would look pretty on you bike for half an hour.

stuessenhigh Posted April 17, 2005 Report Share Posted April 17, 2005 I have a little gizmo..bout the size of a penknife that meassures the pitch of the thread. (you might be able to buy one of these at the hardware shop??) Diamater, just meassure with your vernier (sp?) callipers.......(same with length) Its a good idea..I would rather have alan key bolts in those places than the philips screw ones..and will follow this thread to see how you get on. Sorry my Beta is not with me at the mo. so I cant go and meassure for you. HOPEFULLY someone else will. Good luck. STU Quote Link to comment Share on other sites More sharing options...
mercury Posted April 17, 2005 Report Share Posted April 17, 2005 Threads on most new bikes are metric course. If you measure the diameter of the threaded bit it will tell you the size of the bolt. I think the bolts to the mudguards are m5, i used stainless button heads no sharp edges to catch hope this helps. mercury Quote Link to comment Share on other sites More sharing options...

flo Posted April 19, 2005 Report Share Posted April 19, 2005 bolt are measured in length from the underside of the head not including the head, the rest has all been covered above Quote Link to comment Share on other sites More sharing options...
subira Posted April 19, 2005 Report Share Posted April 19, 2005 Unless its countersunk, then its the entire length including the head. Quote Link to comment Share on other sites More sharing options...
kinell Posted April 19, 2005 Author Report Share Posted April 19, 2005 I managed to nip out and get the bolts yesterday, they all fitted perfectly with just one small problem: - The M5 and M6 bolts use different sized allen keys, which buggered up my plan to try and standardise as many fixings as possible BTW, I bought the plain jane stainless steel bolts and not the fancy red and blue ones - coz I'm not a tart Quote Link to comment Share on other sites More sharing options...
dabber Posted April 20, 2005 Report Share Posted April 20, 2005 Mozchops - can you put together a kit to standardise to a single allen key size for Sherco with stainless bolts? If so how much? Quote Link to comment Share on other sites More sharing options...
mozchops Posted April 20, 2005 Report Share Posted April 20, 2005 not really dabber without great expense but most fasteners on trials bike take either a 4,5 or 6mm hex key which isn,t that bad.If needs be bring your screws in and i'll see what i can do for you.

nigel dabster Posted April 20, 2005 Report Share Posted April 20, 2005 Don't forget the carb top ones which can be swapped too and there is an allen bolt swap for the airbox clip which matches all the others (4mm?) rather than smaller, guess thats what your after dabber? Don't forget to keyhole the rad cover thats a help on Shercos too I've found. Quote Link to comment Share on other sites More sharing options...
