Not really a high street sort of purchase tbh. I use either bearing suppliers or engineering tool suppliers to buy any. example of which I use.... http://www.jlindustrial.com/Adhesives_and_Lubrication/Loctite/2030/4294966270.html Possibly Halfords but I doubt it.
You'd need a motor factors - deffo not Halfords. RS components do it, as do Silverstone factors if you're anywhere near the circuit. Believe it changed to '271' BTW
