Custom machined part
Plastic standoffs
- Job
- Set installed height
- Ends
- Female or male
- Threads
- Cut or inserts fitted
- Materials
- Plastic or soft metal
Custom machined standoffs that mount a board, panel or component at a set height, in engineered plastics, aluminum, brass or bronze. Made to your drawing or from the old part, from one piece to production runs.
- ±0.002"–±0.005" on critical dimensions
- Family owned in Aurora since 1986
- Expedited service for breakdowns
What we machine to
Height, two ends and the body between
A standoff sets the distance between two surfaces and carries the fastener between them. Read yours top to bottom.
-
Top end Mates to the board or panel
Female thread, male stud or plain bore. Thread size and engagement depth.
-
Body Round or hex
Outside diameter or across-flats size, plus any shoulder, flange or counterbore.
-
Installed height The key dimension
The distance it sets between the two surfaces. Held to the tolerance on your drawing.
-
Bottom end Mates to the chassis
Female thread, male stud or plain bore, the same choices as the top end.
-
Through bore If the fastener passes through
Bore size and whether it runs the full length.
Common configurations
- Female–female
- Male–female
- Male–male
- Plain bore
- Shouldered
- Flanged
- Hex body
Replacing a standoff?
Why standoffs are replaced
Common reasons, not a diagnosis.
Send the old standoff with the hardware it mates with, and tell us whether the height, threads or faces are worn.
- Stripped or pulled-out threads Threads that let go during assembly or under load.
- Lost height The standoff has shortened under a constant clamping load or heat.
- Cracked shoulder Cracks where the body steps down to a shoulder or stud.
- Distorted mounting face A face that’s no longer flat against the board or chassis.
- Loosening Fasteners that won’t stay tight in the standoff.
- Size change Moisture growth in some plastics, such as nylon.

Materials for standoffs
Chosen by what the standoff needs
Name the material and grade on your drawing, or tell us how the part is used and we’ll suggest suitable materials. These are common choices; we machine most engineering plastics.
-
Insulating
Where the standoff must not conduct between the board and the chassis.
-
Metal
When the standoff needs to be metal.
Static-dissipative grades are also machined. Tell us whether the part must insulate or provide a dissipative path.

Standoff FAQs
Something else? Call (630) 904-2525.
A standoff sets a height and carries the fastener, usually through threads at its ends. A spacer is a plain sleeve that sets a gap. Your drawing decides which you need, and we machine both.
We hold ±0.002" to ±0.005" on critical dimensions, depending on the material. We confirm the installed height and other critical dimensions with the quote.
Timing depends on the standoff, material and quantity, and comes with your quote. For an emergency breakdown, ask about our expedited service.
Not a standoff?
What does yours do?
Mounting parts are easiest to name by their job. We machine almost any plastic part, so if yours isn’t here, describe it in a quote request.
