Britool Hallmark 1/2"SD Imperial AF Hexagon Impact Sockets - 7/16 - 1'1/4"AF

These Britool Hallmark impact sockets are engineered from premium Chrome Molybdenum Alloy, providing exceptional strength and durability for demanding applications. Designed for use with high-power pneumatic tools such as impact wrenches, they deliver reliable performance under heavy torque loads.

Each socket includes a ball-retaining groove on every face of the 1/2" square drive, ensuring a secure connection with all compatible accessories. A dedicated pin-and-ring hole adds an extra layer of safety by allowing the socket to be positively locked onto impact wrenches during high-torque operations.

Featuring a Hexagon (6-point) Stress Relief Drive, these sockets maximise torque transfer while reducing the risk of fastener rounding or damage. Strong, precise, and safety-focused, they represent trusted Britool Hallmark engineering.
