Model

Heat-set threaded inserts turn appropriately sized holes in plastic parts into strong reusable metric connections. This Ktehloy assortment contains 400 brass female-thread inserts across M2, M2.5, M3, M4, M5 and M6 sizes for 3D-printed components, electronics assemblies and molded plastic repairs. Clear internal threads accept matching fasteners, while 45-degree angled knurling increases resistance to turning and pulling out after installation.

The inserts can be installed with controlled heat, ultrasonic equipment or during injection molding and are listed for thermoplastics such as PLA, PETG, ABS, PPS and PP. Brass is described as withstanding temperatures above 300°C or 572°F. Match the insert dimensions and thread to the part, size the hole for the chosen insert and press it straight while the plastic softens. The documented 400-piece kit does not claim installation tips or tools; other variants differ in size, material and count.
