Material: threaded insert; Manufactured internally from high quality brass which guarantees resistance to corrosion. Corrosion and conductivity thermal resistance, resistance to oxidation, hardness high, resistance to deformation under high pressure and good durability. Features: Due to the geometry of the threaded sleeve, it is firmly connected to the threaded sleeve. at the pressure part. The knurled nuts with counter spiral ensure very balanced tightening and loosening torques and high tightening forces. Aim: The nut is made of high-quality brass, which has excellent conductivity; thermal resistance, resistance to corrosion, resistance to oxidation, hardness high, no deformation under high pressure, and good durability. Original CNC kitchen threaded insert for inserting 3D-printed plastic parts (PLA, PETG, ABS etc.) Scope of delivery: 50 threaded nuts in brass M2 x 4 mm.
