Hi.
It comes in a stanley repair kit for the 78

Stanley Spares Kit 14 No 78 Lever & Depth Gauge

if your in the UK the kit is around £16 — Try TOOL LINE
https://www.toollineuk.com/product.php/section//sn/SSP112713

its a lot for 1 screw but if you are an Ebayer you will more than make your money back selling the other spares as not many people seem to know this kit is still made by stanley

Be careful the repair kit isn’t for the 78 Stanley is currently making. I believe those planes are metric.
I found that out when I bought a 78 cheap at an antique mall just for the rod and fence and found it didn’t fit on the older plane.

The original part is whitworth 3/16 -24.
, which might still be available in the UK. Check British motorcycle shops.

In the US, UNC 10-24 shouldered thumbscrews are a working replacement. I see them on EBay for $9.50 for a pack of 10 with free shipping. The same size works on record 043 and 044 planes and other Stanley planes ( 180,190, 289, 50, etc.)
The same size works for the fence rods parts on these planes that have fences.

And my local well stocked ACE hardware has them.

Original parts go on EBay for $20-25. ( free shipping) There are tons for sale when I just checked. They all look like a derusting bath is warranted.

A set with a depths stop goes for $50-$55 .

I see a dealer I often use in the US offers them on EbayUK, but you will get knicked for about £15 shipping.
