What the OpenBuilds Brass Spacer Does

The OpenBuilds Brass Spacer - 5.1x10x1mm (10 Pack) is a small mechanical spacing component used to create a controlled 1 mm gap between parts. It helps maintain alignment, supports consistent hardware stack-up, and separates components in assemblies where accurate spacing matters.

Brass construction makes the spacer suitable for general-purpose mechanical use where a metal stand-off is preferred over a printed or improvised washer. The 10-pack format supports multi-point builds, maintenance, and replacement stock for workshop use.

Key Features and Benefits

• 5.1 x 10 x 1 mm format: Designed for assemblies that require a 5.1 mm inner diameter, 10 mm outer diameter, and a 1 mm thickness.
• Brass material: Offers a durable metal option for spacing, separation, and hardware alignment.
• Consistent stand-off spacing: Useful when a build needs repeatable part positioning across multiple mounting points.
• 10 spacers per pack: Supports batch assembly, spares, and small repairs without mixing unmatched hardware.
• Suitable for custom mechanical builds: Can be used anywhere the listed dimensions match the design requirements.

Where a 5.1x10x1mm Brass Spacer Is Useful

These brass spacers are well suited to CNC assemblies, motion systems, brackets, wheel stacks, panel mounting, and other maker projects that depend on precise component separation. A 1 mm spacer is especially useful for fine adjustments where a thicker stand-off would change alignment or fit.

In repair and prototyping work, the OpenBuilds spacer can help correct hardware stack height, prevent surface contact between adjacent parts, or maintain clearance around rotating or fixed components. For custom fabrication, the value comes from predictable spacing and a compact metal form factor.
