The Socket 80mm 1" Drive CRV Hex is a high-strength tool designed for heavy-duty applications. 80mm: Refers to the socket's size, meaning it is designed to fit fasteners or bolts with an 80mm hexagonal head, commonly used for large bolts or nuts in industrial or automotive tasks. 1" Drive: Indicates the drive size of the socket, meaning it fits a 1-inch drive wrench or ratchet, typically used for larger, more powerful tools and high-torque applications. CRV (Chrome Vanadium): This is a high-quality steel alloy known for its toughness and durability. Chrome vanadium provides superior strength, resistance to wear, and corrosion resistance, making it ideal for heavy-duty use. Hex: Refers to the shape of the socket, which is designed to fit hexagonal fasteners (six-sided nuts or bolts). This socket is typically used in industrial, automotive, and mechanical applications where high torque and strength are needed for loosening or tightening large bolts and nuts.
