Silver Aluminum Alloy Stand-off Spacer (ID: 5mm, OD: 8mm, Length: 20mm)

Product Description

The Silver Aluminum Alloy Stand-off Spacer ID5mm OD8mm L20mm is a premium, non-threaded bushing designed for precise mechanical spacing in your custom builds. With an exact 5mm inner diameter, this sleeve is perfectly sized to slide smoothly over standard M5 bolts and screws, making it an absolute necessity for assembling V-slot wheels, CNC router gantries, and rigid 3D printer frames.

Manufactured from high-strength aluminum alloy, this rigid standoff will not compress, warp, or crack under heavy mechanical tension like printed plastic or nylon spacers often do. The sleek, silver clear-anodized finish protects the aluminum from workshop corrosion and oxidation while providing a clean, professional, industrial look to your machine’s hardware.

At exactly 20mm in length and 8mm in outer diameter, it provides the perfect clearance for separating acrylic plates on laser engravers, mounting heavy-duty stepper motors, or creating rigid standoffs for custom electronics enclosures without adding unnecessary bulk or weight.

Key Features

• Precise Dimensions: 5mm Inner Diameter (perfect for M5 screws), 8mm Outer Diameter, and 20mm Length.

• Premium Material: Made from lightweight but highly rigid aluminum alloy that will not crush under bolt tension.

• Silver Finish: Clean, industrial finish that resists workshop oxidation and corrosion.

• Non-Threaded Design: Smooth inner bore allows for easy slide-on installation over mounting shafts and threaded rods.

• Thermal Stability: Withstands the high temperatures of heated 3D printer chambers (like ABS/PC setups) without softening or melting.

Applications

• Perfect spacing for polycarbonate or Delrin V-wheels on CNC routers and 3D printer linear rails

• Rigid standoffs for mounting custom electronics, power supplies, and stepper drivers

• Separating structural plates on custom Voron builds and DIY laser engravers

• High-strength mechanical spacing for general robotics and workshop automation
