PCB Nut

A PCB nut is a press-fit nut set into a printed circuit board so a screw can fasten a component or a board to a chassis. It is pressed into the board and held by interference rather than by threads in the board.

A PCB nut presses into a hole in a printed circuit board to provide a threaded mounting point. It takes a screw or standoff of the matching thread. It is set with a press or by reflow soldering.

PCB nuts are often made in brass or steel, sometimes with a plating. Brass gives good electrical contact and resists corrosion. Steel gives higher strength where the fixing carries load.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and check the thread, the press-fit diameter and the height against the drawing. On receipt, check thread gauging, plating appearance and that the knurl or barbs are not damaged.
