Bronze Nuts

Bronze Nuts, Bronze Hex Nuts, Bronze Lock Nuts

Conex Metals is a leading Indian manufacturer and supplier of Bronze Nuts and Bronze Hex Nuts. As a non-ferrous metal  major from India, we manufacture and export all kinds of Brass, Copper and Bronze fasteners. We specialize in Bronze Hex Nuts, Bronze Square nuts, Bronze jam nuts, Bronze Cap Nuts, Heavy Hex Nuts, Heavy Hex Bronze Lock nuts etc.  We also make other Bronze fasteners like Bronze Screws, Bronze bolts, Bronze phillips head screws fasteners, Bronze studs-threaded studs, Copper fasteners etc. Bronze Nuts are highly durable fasteners made from Bronze alloys, known for their excellent resistance to corrosion, high tensile strength, and long-lasting performance. They are widely used in demanding environments such as marine, electrical, and industrial applications.

Bronze Material Grades:

Bronze nuts are available in various material grades, including:

• Silicon Bronze (C65100, C65500) – Silicon Bronze Nuts and Silicon Bronze fasteners offer High strength, corrosion-resistant, ideal for marine and electrical applications.
• Aluminum Bronze (C95400, C95500) – Excellent wear resistance and high load-bearing capacity.
• Phosphor Bronze (C51000, C54400) – Superior fatigue resistance, used in precision applications.
• Manganese Bronze (C86300, C86700) – High tensile strength, suitable for heavy-duty applications.
• Leaded Tin Bronze (C93200, C93600) – Good machinability and wear resistance.

Types of Bronze Nuts:

Bronze nuts come in various types depending on their application:

• Hex Nuts – Standard six-sided nuts used in general applications.
• Square Nuts – Four-sided nuts for secure fastening with more surface contact.
• Lock Nuts – Designed to prevent loosening due to vibration.
• Cap Nuts – Protects exposed bolt ends and provides a finished look.
• Flange Nuts – Built-in washer for improved load distribution.
• Heavy Hex Nuts – Larger across-flats dimension for high-stress applications.
• Slotted Nuts – Feature slots for use with cotter pins, commonly used in automotive and mechanical applications.
• Wing Nuts – Feature wings on both sides for easy hand-tightening and removal.

International Standards for Bronze Nuts:

Bronze nuts conform to various global standards:

• DIN Standards: DIN 934 (Hex Nuts), DIN 439 (Thin Hex Nuts), DIN 1587 (Cap Nuts)
• ASTM Standards: ASTM B98, ASTM B150, ASTM B584
• BS Standards: BS 57, BS 1083
