Strong M5 Threads for Bigger Builds
When a printed part mounts to aluminium extrusion, holds a motor or takes a real load, M5 is the thread size to reach for. This pack keeps plenty of both lengths on the bench, so you can design strong, reusable joints into your next frame, enclosure or jig.
M5 Short
At 6 mm long, the short insert suits thinner walls and shallower bosses where a long insert would break through.
M5 Long
At 9.5 mm long, the long insert gives more thread engagement and grip in thick sections and parts that see heavy or repeated loads.
Simple to Install
Set your soldering iron to the filament's printing temperature plus 10°C, rest the insert on a 6.2 mm hole and press it in straight and slowly. Let the part cool before tightening a screw into it.
