Thank you Binch Shin for your tips. I haven't got any luck so far to find any info on the solvent for threadlock in U.K., so I'll get Acetone from nearby pharmacy tomorrow to try. I'll keep posting how it goes here.

Tearing A-bike would be quite a fun! haha
no, I quite like A-bike just the way it is, and doesn't want to break it, really. Actually this mod has a fair reason.
Recently, I installed clipless pedal (Crank bros. Egg-beater S) to my A-bike. Of course this pedal force my feet to be positioned right in the center of the pedal, and nothing is wrong with that as a binding pedal.
However, with A-bike is a different story. The particular bit, where the screws are, is much wider than conventional bicycle, the screws often catches my trousers when I ride. so I decided to change the screws there to minimise the width and smoothness by using the button head screws instead of the original rather edgy socket head screws.
The width of the top tube are,
A-bike (incl. screws) : slightly more than 7cm
Conventional MTB (incl. outer cable) : Less than 5cm (depending on models)
There are
at least 2cm difference.
It depends on each individual's leg shape whether the A-bike's wide top tube bothers or not, I realise I place my feet on slightly outer on the pedal with normal A-bike pedals and my girlfriend and sister --- they have wider pelvis than mine and somewhat pigeon-toe --- their feet tends to be on the outer half of the pedal. I figured this is a result of us involuntary avoiding the screws scratching our thigh.
All these I first noticed at my weekend trip with them to Loch Ness. Interesting.
