Mountain Bike Saddle Bolt Screw size?

6
Found 15th Mar 2014
Does anyone know the name and size of the Screw bolt with the Allen Key top that connects the bike seat to the post via the two clamps? The Thread on mine has nearly worn due to some Dodgey cheap Allen Keys, and my bike seat is becoming very loose, also do you know anywhere online that sells the Bolt?

Thanks

But thanks for your input anyway.Regards Kevhttp://www.ebay.co.uk/bhp/seat-clamp-bolt

Oh sorry Kev, I'm no bike expert as you can tell !
Well I'm pretty sure the seat post clamp bolt, is called a seat post clamp bolt.....

Only £3 for a new clamp with bolt...............

Just measure the diameter of the hole that the seat fits into the frame, only 2 sizes I think....
Id suggest you take the bolt to any local DIY store and match it against those on sale for one with a comparative size and length.
Alternately any good bike shop should be able to help out and it should only be £3-4 at most,you might also invest in a decent set of foldable allen keys whilst your there to prevent any further issues.
