3/16" Hex Male-Female Standoffs
3/16 hex male female standoffs are threaded spacers with a hexagonal body, a male post on one end, and a tapped bore on the other, maintaining a 3/16" gap between circuit boards, panels, and mounting surfaces. At this body length, these standoffs suit compact stacking assemblies that require precise, low-clearance spacing without significant overhead height.
The hexagonal body provides flat-to-flat engagement for wrench or socket installation, and the male-female configuration makes these standoffs well-suited for multi-board PCB stacks in small electronic enclosures.

What Are 3/16" Hex Male-Female Standoffs?
Male-female standoffs are the standard hardware for PCB stacking. A screw at the base threads into the female bore to secure the lower board, while the male post on top accepts the next board in the stack. At 3/16", the body length provides just enough clearance for component leads and solder joints while keeping the stack compact.Female-female standoffs accept screws on both ends without a post and are used where boards or panels attach to fixed surfaces individually. Unthreaded round spacers provide height separation for clearance-hole assemblies where threading into the spacer body is not required.

Applications
3/16" hex male-female standoffs are used in compact electronic and electromechanical assemblies:- Compact PCB stacking in enclosures with limited vertical clearance
- Board-to-board mounting in automation, robotics, and instrumentation
- Control panel assemblies with tight height budgets
- RF and EMC shield standoff configurations
- Prototyping and evaluation board setups
Selection Guidance
Standoff vs. Spacer: Male-female standoffs provide threaded engagement across a stacked assembly. For simpler applications where a single bolt passes through the full height gap, an unthreaded spacer is sufficient.- Measuring Spacing: The 3/16" body length equals the standoff's height contribution. Account for PCB thickness and fastener head dimensions in total stack height calculations.
- Material Selection: Nylon works well for electrically sensitive or lightweight applications. Brass provides reliable thread engagement in production builds. Stainless steel suits harsh or corrosive environments. Aluminum offers a lighter metal alternative.
- Hex vs. Round Body: Hex bodies are the preferred choice where torque control or anti-rotation performance is needed, particularly in high-density assemblies where post-installation movement must be avoided.
