What to Look for in a Brass Round Spacer for PCB Mounting
When you need to space a printed circuit board (PCB) off a mounting surface, a round spacer is a straightforward solution. The key decisions are material, length, and pack size. Brass is a common choice because it is corrosion-resistant, conductive, and easy to machine. A 1/8" length is often used for light standoffs where you need a small, consistent gap.

Brass provides good corrosion resistance and electrical conductivity for electronic applications. The 1/8" length is suitable for creating a small, uniform gap between a PCB and its mounting surface. The 100-piece pack is economical for multiple assemblies or prototyping.

Choosing the Right Length and Pack Size
The 1/8" length is a common choice for PCB standoffs, but you should verify the required gap for your specific board and components. If your assembly needs a different height, look for spacers in other lengths. The 100-piece pack is a good value if you are building several units or need extras for testing. For a single repair, a smaller pack might be more practical, but this product is sold only in the 100-piece quantity.
What the Catalog Does Not Tell You
The catalog does not specify the inner diameter (hole size) or outer diameter of these spacers. You will need to measure or request this information from the supplier to ensure the spacer fits over your mounting screw or standoff. Also, the finish is listed only as "Brass" — if a specific plating or coating is required for your environment, confirm with the seller before ordering. Finally, this item is excess stock and sold non-cancelable, non-refundable, and non-returnable, so verify your dimensions and quantity carefully before purchase.
