Anodized Aluminum Thick Flat Washers — M8 & M10, Red & Black, Thickness 5–20mm

Standard steel flat washers add unnecessary weight and are prone to surface corrosion in lightweight precision builds where a clean, color-matched anodized finish is needed — a real limitation in RC model frames, FPV drone assemblies, bicycle frame builds, and DIY modification projects where both function and appearance matter. These anodized aluminum thick flat washers are available for M8 and M10 bolt sizes in Red and Black anodized finishes, with thickness options from 5mm to 20mm, giving builders a precise, lightweight, color-matched washer solution that doubles as a spacer or seal washer for applications requiring a thicker bearing surface or a specific standoff gap under the bolt head or nut.

Each washer is machined from high-strength aluminum alloy with an anodized surface treatment for excellent corrosion resistance and rust prevention. The flat washer profile distributes clamping load over a larger bearing surface area, reducing the risk of pull-through or surface damage on softer materials. The thick body (5mm to 20mm) provides a significant standoff gap under the bolt head or nut, making these washers suitable for use as spacer washers, seal washers, or load-distributing thick washers in applications where a standard thin flat washer would not provide sufficient bearing surface depth or gap. Tolerance: ±0.3mm.

These anodized aluminum thick flat washers are widely used in aerospace industry components, aviation model toy accessories, high-end aluminum alloy bicycle frame assembly, golf club head assembly, mechanical equipment, mold processing, computer case accessories, and any lightweight precision build where a color-matched, corrosion-resistant thick flat washer provides both functional load distribution and a clean anodized color accent to the finished assembly.

✅ M8 series: ID 8.2mm × OD 16mm, thickness 5 / 8 / 10 / 12 / 16 / 20mm. M10 series: ID 10.5mm × OD 20mm, thickness 5 / 8 / 10 / 12 / 15 / 20mm. Anodized finish in Red and Black. Tolerance: ±0.3mm. Compatible with M8 and M10 metric bolts and screws. Select your Dimensions (ID × OD × Thickness) and Color from the variant options above.

✅ Key Features of These Anodized Aluminum Thick Flat Washers

📏 Thick Body (5–20mm) — Spacer Washer, Seal Washer, or Load-Distributing Thick Washer: With thickness options from 5mm to 20mm, these washers go well beyond the function of a standard thin flat washer. The thick body provides a significant standoff gap under the bolt head or nut, making these washers suitable for use as spacer washers (to set a precise gap between two surfaces), seal washers (to provide a wider sealing surface under the bolt head), or load-distributing thick washers (to spread clamping load over a larger bearing surface depth in softer materials).
🔧 Flat Washer Profile — Wide Bearing Surface, Reduced Pull-Through Risk: The flat washer profile distributes clamping load over a larger bearing surface area than the bolt head or nut alone, reducing the risk of pull-through or surface damage on softer materials such as aluminum panels, composite frames, and plastic enclosures. The OD 16mm (M8 series) and OD 20mm (M10 series) outer diameters provide a generous bearing surface relative to the bolt size.
⚡ High-Strength Aluminum Alloy — Lightweight, Non-Magnetic, Corrosion Resistant: Machined from high-strength heat-treatable aluminum alloy with good mechanical performance, good wear resistance, and good corrosion and oxidation resistance. Significantly lighter than steel washers of the same dimensions and non-magnetic, making these washers ideal for weight-sensitive and magnetically sensitive precision builds such as RC models, FPV drones, bicycle frames, and computer case assemblies.
🎨 Red & Black Anodized Finish — Color-Match or Accent Your Build: Available in Red and Black anodized finishes to color-match your RC model frame, bicycle component, computer case, or DIY build, or to provide a bold color accent at each fastener location. The anodized finish is integrated into the aluminum surface for a hard, color-fast layer that resists fading and chipping under normal use conditions.
🔘 Two Bolt Size Series — M8 (ID 8.2mm, OD 16mm) & M10 (ID 10.5mm, OD 20mm): The M8 series (ID 8.2mm, OD 16mm) is sized for M8 metric bolts and screws with a standard M8 clearance bore. The M10 series (ID 10.5mm, OD 20mm) is sized for M10 metric bolts and screws with a standard M10 clearance bore. Both series are available in the same thickness range for consistent appearance across mixed M8/M10 fastener assemblies.
🔬 ±0.3mm Precision Tolerance — Consistent Fit on M8 and M10 Bolts: Manufactured with ±0.3mm tolerance for consistent inner bore, outer diameter, and thickness dimensions across all available size and color combinations. Good usability and easy to install — simply slide over the M8 or M10 bolt shank and position under the bolt head or nut before tightening.

🎯 Who Is This For?

❓ Frequently Asked Questions

What is the difference between these thick flat washers and standard thin flat washers?

Standard thin flat washers (typically 1–3mm thick) are used primarily to distribute clamping load under a bolt head or nut and prevent surface damage. These thick flat washers (5–20mm thick) provide all the same load-distributing function but also act as spacer washers (setting a precise gap between two surfaces), seal washers (providing a wider sealing surface under the bolt head), or decorative raised washers (providing a visible color-accented standoff effect at each fastener location). The thick body makes them suitable for applications where a standard thin washer would not provide sufficient bearing surface depth or gap.

How do I read the dimension notation for these washers?

The dimension notation uses three values: ID (Inner Diameter — the bore through which the bolt passes), OD (Outer Diameter — the outside width of the washer), and Thickness (the height of the washer body). For example, M8.2 × 16mm × 10mm means Inner Diameter 8.2mm (fits M8 bolts), Outer Diameter 16mm, and Thickness 10mm. Select your preferred combination from the Dimensions dropdown above.

Are these washers compatible with standard M8 and M10 bolts?

Yes. The M8 series has an inner diameter of 8.2mm, which provides standard M8 clearance for M8 metric bolts and screws (8mm nominal shank diameter). The M10 series has an inner diameter of 10.5mm, which provides standard M10 clearance for M10 metric bolts and screws (10mm nominal shank diameter). Both series are compatible with standard metric bolts and screws of the corresponding size.

Are these washers lighter than steel flat washers?

Yes. Aluminum alloy is significantly lighter than steel — typically about one-third the weight for the same dimensions. These washers are also non-magnetic, making them suitable for applications where magnetic interference must be avoided, such as near sensitive electronics or sensors in RC models and drones.

Will the anodized color fade or chip over time?

The anodized finish is integrated into the surface of the aluminum rather than applied as a paint or coating, making it generally more resistant to fading and chipping than painted alternatives under normal use conditions. Hard impacts or heavy abrasion may leave marks, as with any aluminum hardware.

Can these washers be used outdoors?

The anodized aluminum alloy construction provides good corrosion resistance and oxidation resistance, making these washers suitable for many outdoor applications under normal weather conditions. For highly corrosive environments (salt spray, prolonged immersion), stainless steel washers are generally recommended instead.

What thickness should I choose?

Choose the thickness based on the gap you need to set between the two surfaces being fastened, or the bearing surface depth required for your application. Thinner options (5–8mm) are suitable for standard load-distributing washer applications with a modest standoff gap. Thicker options (12–20mm) are suitable for applications requiring a significant spacer gap under the bolt head or nut, or a deeper bearing surface in softer materials. See the product images for visual reference of each thickness option.
