What is a 2H Lock Nut?

A 2H lock nut, also known as a double hex lock nut, is a type of fastener designed to secure and maintain the position of a bolt or screw. It features two hexagonal sections, allowing for increased grip and resistance to loosening under vibration or torque. Typically made from steel or other durable materials, 2H lock nuts are commonly used in machinery and structural applications to ensure reliability and stability.
