Custom Spacers, Bushings & Standoffs
From a Sketch

A spacer is the easiest part in the world to order from a drawing — it's defined by four numbers. Send a hand sketch or just the dimensions, and we machine it to your exact OD, bore, length and thread. No CAD software needed.

The Part You Draw on a Napkin

Most people who need a spacer, bushing or standoff don't need a CAD model — they need a specific size that no catalog stocks. The bolt is too long, the bore is metric and the shelf is imperial, the stack-up is 11.5 mm and McMaster jumps from 10 to 12. That's not a design problem; it's a sourcing dead end.

It's also the single best part to order from a hand drawing. A spacer is geometrically simple — a tube with a hole — so a rough sketch with four measurements tells us everything we need. We redraw it as a proper CAD file for free, confirm the numbers with you, and machine it on our lathes to the exact size. One piece or a thousand.

The 4 Numbers We Need

Write these on your sketch (or just type them in a message) and we can quote:

OD
Outside Diameter
How wide the spacer is
ID
Bore / Inside Ø
The hole — the bolt or shaft size it fits over
L
Length
The gap it has to fill
+
Thread / Finish
Threaded standoff? Anodized? Tell us

Metric or imperial — both fine. If you only know three of the four, send what you have and we'll ask one short question. If the spacer has to press onto a shaft or into a housing, just tell us the mating size and whether it should be a press fit, slip fit or running fit — we machine the bore to the right tolerance class for you.

What We Make From Your Sketch

Round & stepped spacers

Plain tube spacers and shouldered/stepped spacers that locate as well as space. Any OD/ID/length combination.

Bushings & sleeves

Plain bearing bushings, liner sleeves and reducers — bore machined to press-fit, slip-fit or running-fit tolerance.

Threaded standoffs

Male-female, female-female and male-male standoffs in any length and thread, metric or imperial, hex or round.

Wheel & hub spacers

Vehicle and motorsport spacers with the exact bore, thickness and bolt pattern your build needs.

Flanged bushings

Shouldered/flanged bushings that locate against a face — common in linkages, pivots and rollers.

Insulating & plastic spacers

Non-conductive spacers in Delrin, PEEK or PTFE for electrical, thermal or low-friction jobs.

Materials & When to Use Them

MaterialBest forNotes
Aluminum 6061 / 7075Lightweight spacers, wheel spacers, general useAnodize black, silver or color; 7075 for higher strength
BrassBushings, electrical spacers, decorativeGood machinability, naturally corrosion-resistant
Stainless 303 / 316Marine, outdoor, hygienic, high-load316 for saltwater/chemical exposure
Carbon & alloy steelLoad-bearing spacers and bushingsCan be hardened or zinc-plated
Delrin / POM, PEEK, PTFEInsulating, low-friction, lightNon-conductive; PEEK for high temperature

Not sure which to pick? Describe what the spacer does — what it sits between, the load, the environment — and we'll recommend the material with your quote.

Catalog jumps over your size? That's the whole point of this service. Stock suppliers carry standard increments; we machine to your number. Non-standard OD, odd bore, in-between length, mixed thread — drawn by you, made by us, from one piece.

How It Works

01

Send Your Sketch or Dimensions

Email a photo of your sketch — or just type OD, ID, length and thread — to [email protected] or via the form. Note the material if you know it.

02

We Redraw & Confirm

Our engineer turns it into a CAD drawing within 24h and confirms any fit/tolerance question — we never assume a press fit you didn't ask for.

03

You Approve & We Quote

You approve the drawing; we send a firm price with material options and lead time. Tiered pricing for 1, a few, or a batch — all upfront.

04

We Turn, Inspect & Ship

Machined on our lathes, dimensionally inspected, anodized if requested, and shipped worldwide via DHL/FedEx with tracking.

Real Job: Wheel Spacers From a Pencil Sketch

A UK motorsport customer sent a pencil sketch with a bore, a thickness and a bolt pattern — no CAD, no formal drawing. We redrew it in four hours, confirmed the bore for a hub fit, machined the pair from 7075-T6, black-anodized and laser-marked them, and delivered in 12 days. Zero rework.

Frequently Asked Questions

+

Yes — that's the ideal input. OD, bore, length and any thread/finish is enough to quote and machine. We redraw it as CAD for free and confirm every number before cutting. No CAD software needed on your side.

+

Yes. Tell us the shaft or housing size and whether you want a press, slip or running fit. We machine the bore to the matching tolerance class (typically ±0.01 mm) so it seats correctly.

+

Yes, MOQ is 1 piece with no setup fee. Order one to confirm the fit, then reorder a batch at a lower unit price — we keep your CAD on file.

+

Both. Draw it in whatever units you think in — millimetres or inches — and we'll machine to it. We can also convert and confirm if you mix the two.

+

Yes — black, silver/clear, and common colors (red, blue, gold, etc.). Laser marking is available too. Just note it on your sketch.
