Hex Jam Nuts

Delta Fitt Inc. is a trusted Hex Jam Nuts Manufacturer offering precision-threaded fastening solutions made from stainless steel, galvanized steel, brass, copper, and alloy steel. Hex jam nuts are thinner than standard hex nuts and designed to lock against another nut, preventing loosening in high-vibration applications. Compliant with standards such as ASTM A563, DIN 439, and IS 1363, these nuts are vital in mechanical assemblies, electrical panels, and construction frameworks where double-nut locking is essential. Their compact profile allows them to fit in confined spaces without compromising fastening integrity. Optimized for B2B use, our hex jam nuts are available in multiple sizes, thread pitches, and coatings to meet industrial, mechanical, and electrical requirements. They provide added security for bolts under stress or load reversal. Delta Fitt Inc. supports bulk orders, customized finishes, and efficient supply chain solutions to serve OEMs, heavy equipment manufacturers, and construction contractors with durable, ready-to-install fastener options.
