size and thread - salisbury axle brake pipe clip supports?

[farmershort]

Hi All,

I'm trying to attach my new brake pipes in a "proper" ish way, and have bought some neat little rubber lined stainless P clips. anyone know what size and thread the screws/bolts are that are supposed to go through the little welded tabs on the axle?

Thanks

Adam

was waiting for some m5 screws to arrive... they have... the don't fit!

using the blunt end of a drill bit, I note that 4mm fite, but 4.5mm doesn't assuming it's catching on the thread, then it's the equivilant of m4.5 ish... 11/64 or 3/16 possibly? God I hate solihull sometimes...

can I just get an m5 tap and convert it straight like that, or does it have to be drilled smooth first?

Drill tap size for m5 is 4.5mm so I guess you would be rearranging the existing thread rather than truely cutting a new one?
Is there enough meat to go m6?

finally found the part number. SL510031 & SL510032 here's a link:

can't find the size anywhere, but it looks like an aggressive thead... 3/16 self tapper possibly?

I think there is enough meat for an M6, yes... but it looks like I should probably be using an m5 self tapper from that pic above.

every day is a school day....

I've just been trying to find some stainless self tappers, and notices that self tappers are in yet another measure of thread diametre... No.8 is 4.2mm and No.10 is 4.8mm.... I think this is starting to make sense finally. I;ve ordered a variety box to see what fits'

Not absolutely sure but i don't think an old Sailsbury axle will have any metric fasteners.

well it's not exactly "old".. it's the genuine original from the 1998 vehicle. These are only welded-on tabs, so essentially this whole thing was fabricated in the late 90's... why oh why landrover...

Will still use a few UNF fasteners. What size are your prop shaft nuts and bolts for instance? Sailsbury axle have been around a very long time.

Yeah I get that, and anything that required proper tooling changes - flange nuts etc - I'd expect those to stay the same out of cost saving if nothing else... but a few poxy self-tappers in some after-thought welded tabs seems like one of the few places where using the standard of the day would make sense. Same goes for those stupid a-frame to chassis bolts... inch and an eigth!!! when every other big nut doing a similar job is 30mm (trailing arms, radius) or 24mm. There comes a point where inconsistancy must cost them money.

ho hum. I'm just annoyed I keep having to buy tools which have only one use! fair enough when it's something like a spray gun... but an inch and an eigth ring spanner?!?! Never in my life will I use that again.... unless I have to strip the a-frame off again.

Just think of the expense us old timers had to go to to buy shitty metric stuff. But at least we have tools for everything.

This is true.... by the end of this project I'll be tooled up for anything from a vespa to the forth road bridge...

Wait til you get something with Whitworth, B.S.F and BA stuff on it.

I reckon I'm one of the few early 30 somethings in the country to have a set of whitworth stuff..... I don't even know how I have it.... that's a sign really isn't it....

For anyone reading this in the future:

Go to screwfix. Buy a box of #10 self tapping screws 1 inch long... Hacksaw them in half. Perfect!

N.b. #10 is not m10... It's the stupid self tapping scale... They're about 4.8mm.

Before you ask... Screwfix don't sell #10 stainless self tappers any shorter than 1 inch. Tbh, even if you managed to buy half inch, you're better off cutting the pointy bit off. It serves no purpose.
