How to select the correct impact socket size for a fastener?

To select the correct impact socket, match the socket size exactly to the fastener head dimension—here, 9 mm for a metric bolt. Ensure the drive size (1/2") fits your impact wrench, and choose a 6-point deep design for high-torque applications and recessed fasteners. Always use impact-rated sockets for power tools.
