The tool to square the blades in a 16x20 four blades Saunders Easel

[Henry Alive]

What tool do you use in order to align the blades in a 16x20 four blades Saunders Easel?
The manual says that there are two hex screws on each actuator that permit squaring the blades. This is true. My problem is that I do not have the appropriate tool, and it is not a good idea to carry the easel to the tool store! I think it could be some kind of Allen Hex Key. Can you help me?
Thanks,
Henry.

Mine uses standard slotted screws for the blades, probably an older model than yours. The frame uses 1/8" allen head socket screws. The hex keys come is inexpensive sets available at almost any autoparts store.

A set of allen keys is only going to be a couple of dollars. Get the fractional set & you'll be covered.

Ok. I will do it. Thanks,
