Category	Industrial & Scientific Fasteners Nuts Square Nuts

Square Machine Screw Nuts are engineered from tough steel and finished with a zinc plating for lasting corrosion resistance. These square nuts are designed to resist loosening under vibration and to provide a secure, non-rotating interface when paired with machine screws.

Material: Steel
Finish: Zinc plated
Type: Square nut
Thread: 4-40 UNC
Compatibility: Accepts standard 4-40 machine screws
Non-rotating design: Square geometry helps prevent rotation and keeps parts aligned
Durability: Hardened steel with zinc coating resists wear and corrosion
Applications: Electronics enclosures, machinery, cabinetry, automotive assemblies

To install, insert the nut into a prepared slot or hole and tighten your 4-40 machine screw to the recommended torque. The zinc finish adds a layer of protection against moisture and oxidation, helping your assemblies endure over time.
