Subject: Re: [TR] TR] Rocker Shaft locating screw

The locating screw is smaller than 1/4 inch.? Hard to tell that in the=20
picture below.? More like a #12 screw.

The locating screw seems to screw into a M6x1 sizer at the hardware=20
store.? But strangely a M6x1 bolt won's screw into the hole.

It appears to be 27tpi according to my gauge.

Looks very close to m5x.8

Thanks,
Roger

Thanks Dave,

I have a couple of the screws. (though mine have a Pozidriv head=20
instead.? The problem is I have 2 rocker shafts that were tapped for the=20
wrong size. So, I am trying to figure out if I could tap them to the=20
right size.

What I said on a previous post was wrong.? I went back to a hardware=20
store and the locating screw slid right into the M6x1 tester with out=20
having to turn it.? So it is smaller than that. It would not go into a M5x.=

I suspect you are right about it being a Whitworth.

Thanks,
Roger

Subject: Re: [TR] TR] Rocker Shaft locating screw

Wikipedia has a fairly comprehensive page on Whitworth bolts
https://en.wikipedia.org/wiki/British_Standard_Whitworth
It looks like it might be a 7/32 which is between M5 and M6.? Good luck fin=
ding one of those.
Moss has them and Rimmer Brothers have them (part no 104859).? I suspect th=
ere is one old bloke in the Lake District who still has the tooling and is =
making them in his retirement.? Such was the nature of the British Auto Ind=
ustry in the early years after the war.
Seriously, I'll bet Rimmer contracted a large quantity (1,000?) be produced=
 and sold half of them to Moss.
But these are hex head rather than Pozidrive.? I have only a passing famili=
arity with machine shop operations but I suspect that making the hex head v=
ersion is much easier to make using an NC lathe and hexagonal feed stock.? =
Making a Pozidrive (or even Philips) would require a stamping operation to =
form the head.? If you insist on Pozidrive maybe you can arrange a swap wit=
h someone who has a Pozidrive screw and is willing to use the hex head.

Thanks Dave,<br>
<br>
I have a couple of the screws. (though mine have a Pozidriv head <br>
instead.? The problem is I have 2 rocker shafts that were tapped for the <b=
r>
wrong size. So, I am trying to figure out if I could tap them to the <br>
right size.<br>
<br>
What I said on a previous post was wrong.? I went back to a hardware <br>
store and the locating screw slid right into the M6x1 tester with out <br>
having to turn it.? So it is smaller than that. It would not go into a M5x.=
8<br>
<br>
I suspect you are right about it being a Whitworth.<br>
<br>
Thanks,<br>
Roger<br>

Wikipedia has a fairly comprehensive page on Whitworth bolts<br>
<a href=3D"https://en.wikipedia.org/wiki/British_Standard_Whitworth" rel=3D=
"nofollow" target=3D"_blank">https://en.wikipedia.org/wiki/British_Standard=
_Whitworth</a><br>
It looks like it might be a 7/32 which is between M5 and M6.? Good luck fin=
ding one of those.<br>
Moss has them and Rimmer Brothers have them (part no 104859).? I suspect th=
ere is one old bloke in the Lake District who still has the tooling and is =
making them in his retirement.? Such was the nature of the British Auto Ind=
ustry in the early years after the war.<br>
Seriously, I'll bet Rimmer contracted a large quantity (1,000?) be produced=
 and sold half of them to Moss.<br>
But these are hex head rather than Pozidrive.? I have only a passing famili=
arity with machine shop operations but I suspect that making the hex head v=
ersion is much easier to make using an NC lathe and hexagonal feed stock.? =
Making a Pozidrive (or even Philips) would require a stamping operation to =
form the head.? If you insist on Pozidrive maybe you can arrange a swap wit=
h someone who has a Pozidrive screw and is willing to use the hex head.<br>
