Stainless M3 Fasteners for Printed Parts
Nothing stalls a project like finding the right screw in the wrong length. This kit covers the M3 lengths that come up again and again in 3D printed assemblies, in both head styles, with nuts to match.
Countersunk Screws
Countersunk hex head screws sit flush in a countersunk hole, leaving a smooth surface on lids, panels and sliding parts.
Button Head Screws
Button head socket screws have a low profile rounded head for a neat finish wherever the head sits on top of the part.
Hex and Nyloc Nuts
Use hex nuts in printed nut traps, and nyloc nuts where vibration could loosen a joint.
