Title: Help finding missing screws on my N Gauge Jinty Loco ....
Post by: mikepaling on February 17, 2026, 01:29:35 PM
Hi ...
I recently purchased a 2nd hand N Gauge Farish Jinty Loco and I have spotted some incorrect and missing screws on the chassis. I am not sure what sizes they are or what type of thread they have.
Does anybody know what the correct screws are on my attached image of the bottom of my Jinty?

Where I can find and purchase the correct screws to replace the missing and incorrect screws?

Thanks in advance ... Mike

They are all standard screws but you'll probably not find them at screwfix. Some of the N gauge spare/repair sites will carry them and I'd bet https://www.farishnspares.co.uk will be able to tell you which you need to order.

What makes you believe the two marked are incorrect? As far as can be seen from the heads, they are correct for Poole made examples...  (Some Later Chinese produced batches had cross-heads)
As Alan says, any of the regular Farish Spares suppliers is likely to carry them.

Hi Alan ... well for a start the larger Csk headed sticks up as it is too big for the hole it goes in unlike the one next to it which is obviously a cheeshead screw seating in a counterbored hole.

Thanks for the tip about Farish Spares. I will see what they say,
Cheers Mike

dont go undoing the small screw "correct cheese head screw" unless you are familiar with these farish chassies--or you will wonder why the loco wont work anymore

Then unfortunately you will be disappointed because the Spares that will be supplied - which are the same spec as original Factory-fitted - will be the same as the (what you consider) "incorrect" screws currently fitted...  :(

Who knew Farish had been using "the Wrong Screws" for 40-odd years...  :uneasy:


The cheese-head is deliberately different and serves a different purpose as an electrical conductor, rather than securing the chassis.
On those Jinty Chassis, TBH the rear corner screws are not strictly necessary.

Assuming it's a UK made model, all looks correct bar the one missing screw. The thread is 8BA for the larger countersunk screws with the smaller cheesehead one being 10BA. The fixing screws on either side of the chassis will be 1/4" long. The other one will be this length if it's  just holding the keeper plate to the chassis, if it goes through into the chassis it's either 3/8 or 1/2", can't quite remember which.
