Description

Brass heat-set threaded inserts for 3D-printed parts and plastic components — press them in with a soldering iron or heat-set tool and you get a strong, reusable M3 thread in PLA, ABS, PETG, and other plastics.

Key specs (verified):

• Thread: M3; height: 5.7mm; outside diameter: 4.6mm
• Material: brass — high strength, good corrosion resistance, excellent thermal conductivity
• Knurled outer surface for strong holding power in the plastic
• Install by heat or ultrasound; fits most standard heat-set tools
• Compatible with PLA, ABS, PETG and other plastics

100 pieces per pack — enough for a fleet of printed enclosures, brackets, and mounts. Ideal for 3D-printed parts, DIY projects, electronic devices, and mechanical components.
