Safe dial screws

[DIY Dave]

Quick question-I'm working on a couple safe lock displays made of acrylic, but the safe locks I have don't have screws with them so I'm not sure what size I should drill and tap the dial ring screws. I want them to be to specs, like a safe would be. Any help is appreciated. I'll post pictures when I'm done

If they do not come with screws, just get some that will fit.

"...drill and tap four holes for the attaching screws (1⁄4" X 20 or M6 for metric applications)."
Now correct me if I am wrong, but that means 1/4" in diameter and 20 threads per inch.

Found that under Installation Notes on page 2

1/4" OUTSIDE diameter. Need to have a drill slightly smaller, or there will be no threads.

A 13/64'' drill would be good for that.

Thanks for the help, but I think you are looking at the instructions for mounting the lock body, they are 1/4-20. I ended up using 3/16'' screws because I had the tap and screws handy.


When I was looking for how to hand the lock, I found this document that says they use 8-32 machine screws

Reading comprehension, who needs it? Not this commenter!

Why is that? I wasnt able to find any documentation on what size screws it uses

"This commenter" being me, flywheel. I didn't read and comprehend that you were looking for dial screws. Instead I focused on "safe lock" and looked for those screws.
The remark was meant to be a self-deprecating "duh!" and not an insult towards you.

True, that is what you'd see on a chart. I was leaning more to the 'give it a bit of slack' side to make tapping easier. Would've been fine for this application. It's all academic now, but I thought there was more chance the OP might've had a 13/64'' drill to hand, rather than a number 7.
