Beduan 3/8"-16 Serrated Flange Hex Lock Nuts 304

Product Description

The Beduan 3/8"-16 Serrated Flange Hex Lock Nuts are engineered for secure, long-lasting fastening in demanding applications. Manufactured from high quality 304 stainless steel (18-8), these nuts offer outstanding resistance to rust and corrosion, making them ideal for both indoor and outdoor use. Compared to brass or iron hex nuts, the durable stainless steel construction ensures a longer service life, even in harsh environments. Each nut features a standard 3/8"-16 thread, providing compatibility with a wide range of bolts, studs, and threaded fittings. The classic hexagonal shape allows for easy installation and removal using common hand tools such as wrenches or sockets. This design ensures a strong, reliable grip and simplifies maintenance or adjustments in the field, workshop, or production line. A key advantage of these lock nuts is the integrated serrated flange. The flange increases the bearing surface, distributing load more evenly and reducing the risk of damage to the connected material. The serrations bite into the mating surface to help prevent loosening caused by vibration or dynamic loads, reducing the need for additional washers or locking devices. This makes them an excellent choice for machinery, automotive, construction, and general industrial applications where reliability is essential. With a bright finish, these 304 stainless steel lock nuts not only perform well but also maintain a clean, professional appearance over time. Supplied in a convenient pack of 50 pieces, they are suitable for both small projects and larger production runs, ensuring you have the right fastener on hand when you need it. Choose Beduan 3/8"-16 Serrated Flange Hex Lock Nuts for a secure, corrosion-resistant fastening solution that combines strength, ease of use, and long-term performance.
