3/16" Hex Female Standoffs
3/16 hex female standoffs are threaded spacers with tapped bores at each end and a hexagonal body for wrench installation, providing a precise 3/16" separation between PCBs, chassis surfaces, and panels. This body length sits between the minimal clearance of 1/8" standoffs and the more widely specified 1/4" size, making it a practical choice for assemblies with specific height requirements that fall between standard options.
These standoffs are used for layered electronic assemblies, compact enclosure builds, and any application where exact 3/16" board clearance is specified in the design.

What Are 3/16" Hex Female Standoffs?
Hex female standoffs are threaded on both ends and accept a screw at each face, holding a PCB or panel at a controlled spacing. The 3/16" body length serves assemblies that need a little more clearance than 1/8" standoffs provide, while remaining more compact than 1/4" versions.Male-female standoffs include a pass-through male post for board stacking applications. Unthreaded round spacers are appropriate where height separation is achieved through a clearance bore with a through-bolt rather than threaded engagement at the spacer itself.

Applications for 3/16” Hex Female Standoffs
3/16" hex female standoffs are found across a range of industrial and electronic assembly applications:- PCB-to-chassis mounting in compact electronic assemblies
- Board stacking in automation, instrumentation, and control systems
- Panel spacing in power supply and data acquisition enclosures
- RF and EMC shield mounting
- R&D and prototyping setups requiring specific sub-1/4" clearances
Selection Guidance
- Standoff vs. Spacer: Female standoffs are threaded at both ends. Use them where individual, threaded fastening is needed at each mounting point. For assemblies where a single bolt passes through the full height gap, an unthreaded spacer may be a simpler choice.
- Measuring Spacing: 3/16" is the standoff's contribution to stack height. Calculate total height by adding PCB thickness and fastener dimensions.
- Material Selection: Nylon is often used for insulating applications and lightweight builds. Brass and stainless steel are corrosion-resistant. Aluminum is a lightweight metal option.
- Hex vs. Round Body: The hex profile prevents rotation during tightening. This is useful in high-density board layouts with limited access or where anti-rotation performance is required.
