M3*20+6MM Brass Hexagon Copper Stud (pack of 5)

The M3*20+6MM Brass Hexagon Copper Stud is a brass hex standoff with an M3 female thread at one end and a 6 mm M3 male thread at the other, sold in a pack of 5. The 20 mm hexagonal body sets a fixed gap between a PCB and its case or between stacked boards, and the male-female design lets you screw several standoffs together for taller spacing.

What's in the Box

• 5 × M3 brass hex standoffs, 20 mm body + 6 mm male thread

Tip: Tighten the standoffs by hand or with a small nut driver; brass threads are softer than steel and strip easily if over-tightened. Brass conducts electricity, so keep the standoffs clear of tracks and pads around the mounting holes.
