I tapped a hole with a 6-48 tap. It didn’t fit well….

Maybe the threads are stretched…

It is 6-48. I checked several parts sites and they all say the 94 screw is the same as other models. I have some 73 forearm tendons and have the 6-48 tap and it threads in. Using a used screw can have rounded threads making it hard to thread in a clean hole.

Pirkle’s book also confirms: 6-48. Maybe try chasing the screw threads?

Technically, the glass is always full; half liquid, half air....

The factory blueprint for the model 73 forearm tip screw shows a .1375″ – 48 TPI thread dimension. #6 machine screws are nominally .138″ diameter, so this is about as close to #6 as you can get. Winchester used this designation and screw size on many screw threads of that era clear up into the 30’s. It was a common size on many of their rifles. On later blueprints, the size was changed to the conventional 6-48 dimension of .140″-48 TPI. 

The drawing also states the same screw was used on Model 86 Lt Wt, 92, 94 and 64. Drawing was later revised to include these later models.
