Machine Screw Mount

Needed to mount a part to a machine, so I developed this method of making a countersunk screw profile perpendicular to the plane of my material. Cut with 1/8" acrylic.

This is a small sample piece - many of the layers can be thicker and larger to your needs. Makes for an easy way to mount to an existing base (in my case a machine).
The rectangular “washers” in the interior guide and hold the screw in position. You can adjust tolerance or turn into slot for less precise mounting.

10-32 machine screw 1-1/2" long. You can adapt to any screw - even self-tapping if needed.

0.125 x 0.625 slotted spring - you can adjust to other pins or other screw mounting.

Machine Screw Perpendicular


Nice. You could sneak some delrin in for the middle layers if needed…

Agreed good thought. I’ve used delrin pins before also.

I like the firm hold of the circular pins - tension is consistent over time and wear in the holes.

I’ve also cut a hex shape in layer to hold a nut and keep it from spinning to receive a smaller machine screw.
