Brass Hex Standoffs for PCB Stacking

This pack contains 20 brass hex standoffs with M4 threads. Each spacer measures 12 mm total length and features 6 mm male and 6 mm female thread sections. They are designed to separate and secure printed circuit boards in electronic assemblies.

Solid Brass Construction with Hex Profile

The gold-tone brass material resists corrosion and provides reliable electrical conductivity where needed. A 6.8 mm hex width allows tightening with a standard spanner or socket during installation. The combined 32 g pack weight reflects the density of the solid brass bodies.

Fixed 12 mm Spacing Limits Layout Flexibility

The 12 mm overall length sets a single board-to-board distance that cannot be adjusted without additional hardware. Projects requiring variable stack heights or taller clearances will need different spacer lengths. The M4 thread size also restricts use to matching M4 hardware only.

Questions about this item

What thread standard and length does the M4 standoff use, and how much clearance does it add?

Each spacer has an M4 thread with 6 mm male and 6 mm female sections, giving a total stack height of 12 mm.

What hex size and board clearance do I need to fit these 20 brass pillars?

The hex measures 6.8 mm across flats, so a 7 mm socket fits, and the 12 mm body sets the board-to-board gap.

How do I install the male-female brass standoffs without stripping the threads?

Hand-tighten the male end into the first board, then use a 7 mm spanner on the hex to snug the female end onto the second board.
