Custom threaded standoffs in 304, 316L, and 17-4PH, with other grades on request. Female-female, male-female, and male-male ends, round or hex bodies, in metric and inch threads, cut to your body length and made to your drawing or sample.
Applications: Electronics and Control Enclosures, Architectural Glass and Signage, Marine Panels and Enclosures, Food Processing Equipment.
These metric threads are the common sizes for standoffs. The tap drill is the bore of a female thread before tapping. Hex across flats varies by maker, so the table shows the common range for each thread. Inch threads, other sizes, other hex sizes, and round bodies are made to your drawing. Body length, male stud length, and finish are set on your drawing. Thread depth in a short standoff runs through the body, and a long standoff is threaded to a set depth at each end.
| Thread | Coarse Pitch | Tap Drill (Female Thread) | Common Hex Across Flats |
|---|---|---|---|
| M3 | 0.5 mm | 2.5 mm | 4.5 to 6 mm |
| M4 | 0.7 mm | 3.3 mm | 6 to 8 mm |
| M5 | 0.8 mm | 4.2 mm | 8 mm |
| M6 | 1.0 mm | 5.0 mm | 10 to 13 mm |
| M8 | 1.25 mm | 6.8 mm | 13 mm |
| M10 | 1.5 mm | 8.5 mm | To drawing |
Send a drawing, a DXF file, or a sample. Our engineers review the thread, the body, and the tolerance before cutting metal, and we CNC machine the part ourselves, so you deal directly with the factory.
We cut female and male threads on the same part, so each thread runs true to the body. Metric and inch threads are made in the same order.
Salt, moisture, washdown chemicals, and load drive the choice between 304, 316L, and 17-4PH. We confirm the grade against your drawing before production, and tiered pricing is available on larger orders.
A standoff has threads on one or both ends, so it screws into a part or takes a screw directly. A spacer is a plain sleeve, and a bolt through its bore holds the assembly. Use a standoff when one side has no through-hole for a bolt.
Choose female-female when a screw enters from each side. Choose male-female when the standoff screws into a tapped hole on one side and takes a screw on the other, as when stacking boards or plates.
Choose 316L where the standoff sees salt, chlorides, or chloride-based cleaning chemicals, because it resists pitting better than 304. Choose 304 for indoor, dry, or mildly humid service, where it costs less.
Body length is cut to your drawing. As the length grows, the standoff bends more under side load, so a long gap is often better held by a tube spacer on a threaded rod. Send the load and the gap, and our engineers will suggest the form.
A quote request needs the type of ends, the thread size and hand, the body length, the body shape and size, the grade, the finish, and the quantity. A drawing or a sample speeds it up.
