Brass 360 heavy jam hex nuts are low-profile fasteners designed for applications with limited space or where a secondary nut is needed to lock a primary nut in place. While they share the increased width across the flats of a "heavy" nut for a larger bearing surface, they are significantly thinner than a standard nut. Forged from Alloy 360—often called Free-Cutting Brass—these nuts offer exceptional machinability and a high strength-to-weight ratio. They are naturally non-magnetic and provide excellent electrical and thermal conductivity, making them a top choice for heavy-duty electrical terminals and grounding systems. Their superior resistance to corrosion and "season cracking" ensures they remain reliable and easy to remove in marine or industrial environments without seizing or rusting.
