Koken 8405A100 1" Square Drive Standard 12 Point 3-1/8" Socket AF SAE Imperial - Made in Japan

Not only the opening that contacts the bolt / nut, but also the square drive on the insertion side is the first in Japan to use a flat drive with surface contact that reliably transmits high torque without damaging the corners. Not only does it not damage the corners of the bolt / nut, but it also disperses the stress applied to the socket and improves the load capacity.
