Metric Bronze Hex Nuts
These nuts are resistant to salt water, electrically conductive, and nonmagnetic.

Bronze Extra-Wide Hex Nuts
These nuts are resistant to salt water, electrically conductive, and nonmagnetic. Also known as heavy hex nuts, they are about 10% wider and taller than standard hex nuts and distribute the load over a large area.

Bronze Thin Hex Nuts
These nuts are resistant to salt water, nonmagnetic, and electrically conductive. Also known as jam nuts, they are about half the height of standard hex nuts. Use them in low-clearance applications or jam one against another nut to hold it in place.

Low-Pressure Brass and Bronze Threaded Pipe Fittings
Use these fittings in low-pressure flow applications. They have good corrosion resistance.
Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration. Locknuts that meet DIN 431 adhere to international standards for locknut dimensions.
