What the OpenBuilds Brass Spacer Does

The OpenBuilds Brass Spacer - 5.1x8x0.8mm (10 Pack) is a small mechanical spacer used to set accurate gaps in hardware assemblies. It helps maintain alignment, control stack height, and separate moving or fixed parts where a thin metal spacer is required.

Brass construction makes the spacer suitable for general-purpose mechanical builds that need a durable, dimensionally consistent part. The 10-pack format supports multi-point assemblies, repairs, and replacement stock for workshop use.

Key Features of the 5.1x8x0.8mm Brass Spacer

• Brass material: Provides a solid metal spacing component for mechanical assemblies.
• Thin 0.8 mm profile: Useful for fine spacing adjustments and stack-height control.
• 5.1 x 8 mm format: Sized for builds that require this specific inner and outer diameter combination.
• Pack of 10: Suitable for projects using multiple identical spacers or for maintenance spares.
• OpenBuilds-style hardware part: Designed for motion-system and frame-based assemblies where precise spacing matters.

Where a Brass Spacer Like This Is Commonly Used

This spacer is useful in CNC, 3D printer, robotics, and maker projects that use bolts, wheels, bearings, or plate assemblies with tight spacing requirements. A thin brass spacer can help reduce misalignment caused by over-compressed stacks or uneven part separation.

In maintenance and custom fabrication work, the spacer can also be used when replacing worn hardware or tuning an assembly to achieve the correct fit. The compact size makes it practical for detailed mechanical builds where a full-width washer or thicker spacer would not be appropriate.
