Plastic spacers crack under load and steel spacers add unnecessary weight — a real problem when you’re building FPV drone frames, PC motherboard brackets, or precision electronics assemblies. These unthreaded aluminium standoff spacers give you a lightweight, corrosion-resistant solution for maintaining precise gaps, alignment, and standoff distances between components.
Machined from high-strength, heat-treatable aluminium alloy, each spacer features a smooth unthreaded bore and a round collar profile. Available in inner diameters from 6.2mm to 10.5mm (for M6, M8, and M10 bolts), outer diameters of 10mm, 12mm, 16mm, and 20mm, and lengths from 1.5mm to 30mm — manufactured to a ±0.3mm tolerance. The natural aluminium finish provides a clean, professional appearance.
These round collar spacer bushes are ideal for FPV and drone frame assembly, RC airplane and car models, PC motherboard and TV bracket mounting, consumer electronics, audio-visual equipment, telecommunications hardware, and any DIY or precision fabrication project requiring a reliable, lightweight standoff or connecting rod.
Ideal for FPV drone frame assembly, RC airplane and car models, and aerospace model builds where lightweight, precise standoff distances are critical for component clearance and structural integrity.
Use as motherboard standoffs, TV bracket spacers, or component mounting bushes in home computers, consumer electronics, and audio-visual equipment assemblies.
Suitable for telecommunications equipment, office machinery, and industrial panel assemblies where reliable, corrosion-resistant spacers are needed to maintain precise component separation.
Versatile round collar spacer bushes for any DIY project requiring connecting rods, tie rods, or support columns — from furniture hardware to custom fabrication jigs.

These spacers are machined from high-strength, heat-treatable aluminium alloy with a natural (uncoated) aluminium finish. The aluminium surface provides good corrosion and oxidation resistance under normal use conditions.
The inner diameter options are 6.2mm (suitable for M6 bolts), 8.2mm (suitable for M8 bolts), and 10.2mm or 10.5mm (suitable for M10 bolts). These are unthreaded spacers — the bolt slides freely through the bore. Select your Inner Diameter, Outer Diameter, and Length from the variant options above.
The three key dimensions are Inner Diameter (d), Outer Diameter (D), and Length (H). For example, a spacer with Inner Diameter 6.2mm, Outer Diameter 10mm, and Length 3mm would be described as d6.2 x D10 x H3. Select each dimension from the variant dropdowns above to find the combination you need.
These are unthreaded (smooth bore) spacers. The bolt or screw slides freely through the bore without engaging any threads. They are designed to be used as standoffs, connecting rods, tie rods, or support columns between two surfaces, with nuts or other fasteners securing the assembly at each end.
These spacers are manufactured to a tolerance of ±0.3mm, ensuring consistent dimensions and reliable fit across all inner diameter, outer diameter, and length combinations.
The aluminium construction offers good corrosion and oxidation resistance, making these spacers suitable for light outdoor use. For environments with constant salt spray or harsh chemicals, additional protective coatings or stainless steel hardware may be more appropriate.
These spacers are commonly used in FPV drone and RC model frame assembly, PC motherboard and TV bracket mounting, consumer electronics and audio-visual equipment, telecommunications hardware, office machinery, and general DIY fabrication projects where precise component separation or standoff distances are required.
