A working stock of M3 stainless fasteners in one box: countersunk and button head screws in five lengths, plus the nuts and nyloc nuts to go with them. M3 is the size most printer parts and maker projects call for, and it matches our M3 heat set inserts.

  • 50 countersunk hex screws: 10 each of M3 x 6, 8, 10, 12 and 20 mm
  • 50 button head socket screws: 10 each of M3 x 6, 8, 10, 12 and 20 mm
  • 40 nuts: 30 hex nuts and 10 nyloc nuts

Every piece is the same part we sell individually, bundled together for a cheaper price than buying each size on its own.

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.
