Hex Flange Lock Nut: Insert, Nylon Insert, 3/4-10, Grade 2 Steel, Zinc Finish MPN:857420BR

The hex lock nut is a versatile fastener that offers an added layer of security to any screw or bolt-fastening application due to its unique design featuring a nylon insert that expands into the threaded hole when tightened, gripping onto the fastener's thread and offering superior torque retention capabilities. Made from grade 2 steel for strength and durability, it is ideal for heavy-duty applications requiring secure fastening in harsh environments where vibration and movement might loosen regular nuts. Its zinc-plated coating adds an extra layer of corrosion resistance to protect the fastener against rust and other forms of chemical attack, making it suitable for use in both indoor and outdoor settings where exposure to moisture or humidity is a concern. With its ability to provide reliable torque retention and resistant to wear and tear, the hex lock nut finds wide applications across various industries such as automotive, mechanical, construction, and general machinery. Its advantages make it an essential component in any manufacturing process or DIY project requiring a high-quality, secure fastening solution that won't fail under pressure or harsh conditions.
