M3 Male to Female Hexagonal Aluminium Standoff Spacer (Pack of 5)

Hexagonal aluminium standoffs with an M3 male stud on one end and an M3 female thread on the other, sold in packs of five. They stack flight controller and ESC boards, hold carbon frame plates apart and lift PCBs clear of a chassis in drone, RC and general electronics builds.

Key features

• Male-to-female threads let standoffs screw into each other, so two short ones can make one taller spacer
• Every length carries the same 6 mm M3 male stud
• Body lengths of 15, 20, 25 and 30 mm, stud excluded
• Sandblasted, anodised aluminium alloy: light, rigid and corrosion-resistant
• Hex body takes a spanner or nut driver for firm tightening

Pick the body length for the gap you need between plates or boards; the stud threads into the next standoff, a nut or a tapped hole. Aluminium conducts electricity, so fit nylon washers where a board's mounting holes sit close to live traces.
