Product description
Are you involved in 3D printing, plastic enclosure design or model making and need to create an extremely strong, durable and reusable metal thread in your plastic parts? The large 170-piece set of M3 and M4 brass thread inserts (Heat Set Inserts) is an indispensable tool for every creative DIYer, designer and professional working with FDM/SLA printers.
Forget about stripped threads directly in the plastic or unreliable bonding of conventional nuts. These special knurled nuts are designed for heat sealing (e.g. with a soldering iron tip) or ultrasonic pressing. They ensure a perfect connection that reliably resists tension, torsion and vibration.
Key advantages that you will appreciate in every project:
Maximum tear-resistance thanks to knurling: the outer surface of the inserts has a cross/spiral knurling (Knurled) that locks firmly into the material when the surrounding plastic melts, preventing the nut from being rotated or pulled out.
Pure and premium brass: The inserts are made of high quality brass with excellent thermal conductivity. This ensures fast, smooth and even sealing without deforming the surrounding printed part.
Precise internal metric threads M3 and M4. Ideal for 3D printer components, robotics or custom electronics.
With this set, you can be sure that you won't run out of fasteners in the middle of a job. Suitable for series and prototype production.
Technical specifications:
For precise modelling of holes in your CAD software, here are the technical parameters:
Product Type.
Internal Thread: M3 and M4 (standard metric)
Material: High quality brass (Brass)
Surface Finish.
Total number of pieces in the package: 170 pieces
Compatible Materials: All common thermoplastics (PLA, PETG, ABS, ASA, Nylon, Polycarbonate, etc.)
Take the quality of your 3D prints and plastic assemblies to an industrial level.
170pcs threaded inserts + PVC box
