Parameter guide

What the parameters mean and how to choose the right values.

Indicates the depth of the threaded post. Choose it according to the material thickness – preferably about 2 mm shorter than the total thickness.

The outer diameter of the threaded post indicates the hole size that needs to be made in the material for it to pass through.

Head diameter defines the size of the visible part of the Chicago screw and the surface area that transfers pressure into the material.

Indicates the length of the male screw that threads into the post. For a secure fit, tighten 2–3 turns and use thread-lock adhesive if needed.

How many Chicago screws come in one pack. Brass and stainless steel screws are sold in packs of 10, the rest in packs of 100, so compare prices per screw rather than per pack.
