Does the 338-piece Gorffy Threaded Inserts kit include the sizes and soldering tips needed for common workshop tasks?
⚡ At a Glance
- • Holding Strength: Knurled brass increases pull-out resistance in plastic substrates
- • Best for: 3D-printing hobbyists, makers and technicians assembling plastic enclosures
- • Not ideal for: Applications where heat cannot be applied during installation
A 338-piece kit of brass heat-set threaded inserts with multiple metric sizes and soldering tips. Designed to create vibration-resistant, reusable threads in 3D printed parts and plastic housings.
Secure, vibration-resistant fastenings, with knurled brass inserts
Knurled machining on each brass insert increases mechanical interlock with surrounding plastic by maximising surface friction. Brass construction also improves thermal conductivity, helping the insert heat and seat evenly into pre-drilled holes.
Robust threaded anchors resist rotation and loosening under load, so assemblies stay tight through repeated use. Ideal for parts that see vibration or frequent disassembly.
Fast, repeatable installation, with heat-set tips and an adaptor
Eight heat-set soldering iron tips and a M4x32mm soldering iron adaptor allow direct heating of inserts for melt-in installation. Heat melts the plastic around the knurls, creating a neat, embedded metal thread without the need for adhesives.
Installation becomes a quick, consistent task suitable for batch assembly or repairs. Reduced fiddliness leads to neater joins and fewer reworks.
Practical coverage for common repairs and prototypes, with a wide metric size range
The kit contains multiple counts across common sizes, including M2, M2.5, M3, M4, M5 and M6 inserts in specified quantities. Variety of lengths and diameters suits thin-walled 3D prints through to thicker plastic housings.
A single kit handles most thread reinforcement needs encountered in hobby projects, product prototyping and small repairs. Fewer trips to the hardware shop and more time assembling or repairing.
