table lamp screw fitting

[Ben]

I've just tried to repair a broken table lamp and the replacement fitting I bought didn't screw onto the base of the lamp as it was a different size. This is a new lamp, I thought they were all one standard size. Anyone know what's going on?

I the good old days they were all threaded 1/2" British Standard Brass thread (26tpi) but all sorts of threads turn up these days on 'furrin' lamps.

I'd hazard a guess at you've got the wrong size fitting.

Looks like you've bought the good old fashioned 1/2 Inch size.

try getting a 10mm one.

the 1/2 inch and 10mm ones are most common types u can get.

Yeah, I've measured them and you're right. The broken one from the new lamp is 10mm and the replacement one they had in the local DIY shop is the old 1/2 inch. Looks like I'll be going to B&Q tomorrow then.

Thanks
