Sealey Walldrive sockets and 9-point sockets the same?

[Yoshi]

Are they exactly the same? I have this crazy idea that the wall drive flats are actually curved inwards towards the bolt flats? Where as a 6-pointer has flat flats of course. Is this right or am I spouting bullshit?

Hopefully I'll be able to get the last rounded off engine mount bolt off my TS250 project with them! Full write up on this with pics to come when I've finished it, including my attempt at making my own exhaust. being that new ones are £320! Pipe bender and welder here I come ay?

if i am right in thinking then a ts250 is a 2 stroke, its going to be near imposssiable for you to make a properly working exhaust system for one of them, tuning expansion chambers and pipe lengh is a black art and if you dont get it right the engine just wont perform that well. Gd luck with it but i think you will be better off buying new ones or getting 2nd hand ones from somewere.

Not heard the term '9 point', but a wall drive socket does have edges curved in; this way a curved section pressed against the flat of the nut, exerting force with the rounded section on the flat of the nut.
This should spread the load over a fair bit bigger area than a normal 6 point which will use a flat section to push against the end of another flat section - creating presumably a fairly small point of contact per side.

on the way ive understood it 6 point socets grip along the flats so give a better area of contact and wont round the bolt off as fast, the 12 point ones are the ones that do most damage to bolts as the force is concentrated on the corners of the bolt.

I've wondered about this before - my thought process went along the lines of:
For a start 6 point sockets tend to be better quality than 12 point, so should be a tighter fit.
However...
presuming there's some amount of space between the two - manufacturer tolerances of the two are unlikely to be /that/ good; when you turn the socket, there's naturally going to be a bit more space underneath the 'rear' section of the face and the 'front' is going to make contact, meaning that pressure is applied to the front faces - if socket and bolt both had 100% perfectly flat faces, this would mean that there would basically only be one point of contact.

Often larger decent 6 point sockets have a cut out on the very corners, presumably to help prevent rounding-off.

You can exert a damn sight more force through a six point socket than you can with a twelve point one. To put it simply a twelve point socket will slip round on the head of a very tight bolt a lot sooner than a six point one ever will.

Yes thanks everyone, I know the pros and cons of 12 and 6 point sockets

I was asking wether Sealey Walldrive sockets (Which are a brand of 6 point sockets) have flat sides or not, compared to generic 6 point sockets.

G was the only one who actually answered my question.
