This range of sockets are from the Britool Hallmark range and are manufactured from the highest quality alloy steel.
Each socket has a ball retaining groove in each face of the sq. drive. This ensures a positive fit with all 1/2" accessories. All sockets have Bi-Hexagon (12 point) Stress Relief Drive to allow higher torque loads to be applied and reduce fastener damage.Made in the Britool UK manufacturing plant before it closed so this range is now very rare.
THE HALLMARK RANGE WAS DEVELOPED BY BRITOOL IN THE 80'S FOR THE AUTOMOTIVE AFTERMARKET. IT HAS BEEN THE PROFESSIONALS CHOICE EVER SINCE. EACH TOOL IS STAMPED WITH A HALLMARK, YOUR GUARANTEE OF QUALITY.
