## Long description

SCHROFF Square Nut M3 SW7 in a pack of 100 is a stainless steel panel fastener designed for reliable M3-threaded connections in electronics chassis, enclosures and mechanical assemblies. The square-body design ensures stable seating and prevents rotation in confined mounting holes, while the SW7 wrench flats provide straightforward tightening with common tools. This fastener is intended for situations where a compact, repeatable M3 connection is required and corrosion resistance from stainless steel is preferred.
Advantages
The square shape offers improved anti-rotation properties compared with round nuts, enabling consistent alignment during assembly. Stainless steel construction provides good corrosion resistance and mechanical durability suitable for industrial and electronics environments. The SW7 wrench flats simplify installation and removal using standard spanners, supporting efficient maintenance and assembly workflows.
Suitable for
Mounting PCBs, brackets and small components inside electronics enclosures
Fastening panels and sheet metal in equipment housings
Mechanical assemblies requiring compact M3 threaded points with anti-rotation features
Service and repair operations where consistent thread engagement and easy tool access are needed
Key specifications
Thread size: M3
Body style: square nut with anti-rotation profile
Wrench flats: SW7 configuration
Material: stainless steel
Pack quantity: 100 pieces
How to use
Select a matching M3 screw or bolt and position the square nut in the prepared panel or enclosure hole so the nut’s flat sides seat against the material to prevent rotation. Use an SW7 spanner or compatible wrench to tighten the mating screw to the required torque for your application, taking care not to exceed the recommended torque for M3 fasteners in thin sheet metal. For removal, loosen with the same tool and withdraw the screw and nut as needed.
Usage recommendations
For reliable assembly, verify hole dimensions and clearances to ensure the square nut seats properly. When used in thin panels, consider backing support or load-distributing hardware if higher torque or vibration resistance is required. Store fasteners in a dry environment to maintain stainless steel surface condition and avoid contamination that could affect installation.
