Knurled Heat Insert Nuts | Brass | Helical / Slanted | For 3D Printing

Precision-machined brass heat-set insert nuts with helical knurling. Specially engineered for installation into 3D-printed thermoplastics (PLA, PETG, ABS, ASA) using a standard soldering iron. The diagonal knurl delivers high pull-out and rotational torque resistance for mechanical assemblies.
