Custom 6061-T6 Aluminum stepped washer
,Countersunk conical spacer with tapered hole
,Aluminum washer for screw locating clamping
Product Description
This aluminum countersunk stepped washer, also named conical stepped spacer, is fully manufactured by one‑piece CNC turning process. Made of high‑strength 6061‑T6 aluminum alloy, the part integrates outer diameter, raised step, central through bore and tapered countersunk cavity in a single machining operation. The surface retains natural bright turning texture with no anodizing or plating, only deburred for sharp‑edge removal. Designed for flat‑head screw pre‑loading and precise axial positioning, our factory delivers reliable custom cnc spacer and provides flexible OEM service according to client drawings or samples. Every aluminum conical washer maintains tight dimensional tolerances to guarantee stable clamping performance for mechanical assembly projects.

Applications
Our aluminum stepped spacer is widely adopted for general industrial equipment assembly, automation fixtures, electronic housing fastener positioning, instrument module installation, mechanical fixture clamping, household hardware fitting, automation machinery connection and precision equipment component assembly. It works as a locating buffer spacer when matched with countersunk fasteners for flush mounting and uniform pressure distribution.
Custom & OEM Service
As a professional custom manufacturer, we provide full‑range OEM custom service for CNC machined stepped washer. You can offer 2D/3D drawings or physical samples for development. We support custom material grades, outer sizes, step heights, countersink angles, bore diameters and tolerance requirements. We produce small‑batch prototyping and mass production orders. Our engineering team checks manufacturability for every custom cnc spacer before formal production.
Key Advantages
- One‑body CNC turning eliminates assembly gaps, solving loose positioning issues of split‑type washers
- Strict tight tolerance control avoids assembly offset and uneven screw compression
- Raw aluminum turning finish keeps stable surface property without coating peeling risk
- Flexible OEM custom service to match unique installation space instead of limited standard sizes
- Consistent batch precision reduces fitting failure and rework cost during client final assembly
Quality Control
We implement full quality control throughout the whole manufacturing flow. Raw aluminum material inspection is carried out before production. Key dimensions of every aluminum conical washer are measured with calipers and micrometers. Sharp‑edge deburr inspection and surface visual check are completed for finished goods. We provide dimension inspection reports upon request for custom orders to guarantee qualified custom cnc spacer output.
Shipping & Delivery
For standard sample orders of our aluminum countersunk washer, lead time ranges from 3‑7 working days. Mass custom OEM production takes 7‑15 working days based on quantity and complexity. We support multiple delivery methods including express courier, air freight and sea freight. Our team arranges secure packaging for precision CNC machined stepped washer to prevent scratch and deformation during transit.
Frequently Asked Questions
Can I get custom size of this aluminum stepped spacer via OEM service?
Yes, as a custom manufacturer, we accept drawing‑based custom dimensions and structure requirements.
What tolerance can you achieve for the custom cnc spacer?
