Square nuts are used in slots, channels and recesses where their flat sides stop them rotating during tightening. Typical uses include strut channel, electrical enclosures, DIN-rail assemblies, furniture, signage and machine frames.
Common standards are DIN 557 (square nuts, regular), DIN 562 (thin square nuts) and ASME B18.2.2 (inch square nuts). Custom thicknesses and sizes are produced to drawing.
Square nuts are machined from 6061-T6 or 2024-T4 square bar, or punched from 5052 or 6061 plate for thinner designs.
Metric M3–M20 coarse and fine threads and UNC/UNF #4 to 3/4 in threads are available, with 6H or 2B tolerance.
Square nuts have a larger bearing area, resist turning in slots and channels, and are easier to hold during assembly in confined spaces.
Natural, clear or colour anodized and chromate conversion finishes are available; conversion coating keeps the nut conductive for earthing.
Yes. They are used for mounting DIN rails, terminal blocks and components in aluminium enclosures, avoiding galvanic corrosion with aluminium panels.
Yes. Square channel nuts with springs or balls hold position in strut channel for easier one-handed installation.
Strength depends on alloy, thickness and thread engagement. They are suitable for light to medium loads; thicker nuts or higher-strength alloys increase thread strip strength.
Yes, but apply anti-seize to prevent galling, and consider isolation in wet environments to limit galvanic corrosion.
Threads are checked with go/no-go plug gauges, and width across flats, thickness and flatness are measured.
Yes. Custom sizes, chamfers, thicknesses and threads are available from an MOQ of 10 pieces.
Yes. They weigh about one third of equivalent steel nuts and do not rust.
Samples are typically available within 2–3 weeks and production within 4–6 weeks.
Please share thread size, width across flats, thickness, alloy, finish and quantity.
