Screw thread

[CHASLON]

Could someone kindly provide me with the details of the screws used to fix the Fr & Rr lights and the chrome H.light bezels onto the body of a 65 S1?
Cheers

All the information you need is in the S1 Factory Fit sticky. Basically the side light lenses are retained by Lucas special slotted screws now available from Richard Smith. Headlight trims are retained by special cross head screws again available from Richard. All were chrome plated.

Thanks for prompt response.
However I did not spot any references to the thread form of the screws used to mount the side and tail lamps to the vehicle body, or to those used to mount the Headlamp bezels to the bonnet. I need to to retap the threads in the fittings that the screws screw into.
In adition, I now find that I need to retap the threads in the side tail light castings that receive the lens screws.
Hope you can help. Thanks in anticipation.

I am pretty sure that they will be BA thread - perhaps 2BA

From the parts book the screws holding the lights to the body are 3/16 UNF (UFS319 1/2" and 7/8" long).

Thanks for help.
The thread fixing the lens to Fr & Rr lamps does indeed seem to be 2 BA.

Having been lent a screw which fixes the lamps onto the car body, I find that it is 0.190" in Dia with 32 tpi - This would seem to be 10.32 unf thread.

I am told (by SNG Barratt) that the reproduction screws used to hold the reproduction chrome headliamp bezel onto the current reproduction bonnets is - 8.32 unc.
However an 8.32 tap was too big for the (damaged) tapped holes in my 1965 factory bonnet. So I guess I shall drill them oversize, tap them and use the 8.32 unc screws.

Cheers.
