SK Hand Tool SK34371 21mm 6 Point Swivel Impact   Socket 1/2" Drive

商品説明

SureGrip(r) Hex Design - The patented SureGrip hex design drives the side of the fastener not the corner. This not only provides increased strength but also avoids the rounding of rusted or damaged fasteners which can occur when using a sharp cornered hex tool.
Extra Deep Recess - The S-K sockets feature extra recess depth to allow for use where threaded fasteners protrude above the nut or where the fastener is domed.30 degree Flex Angle - The 30 degree flex angle on the S-K sockets allows the user to get at hard to reach fasteners. The socket can be positioned to the desired angle because of the heavy-duty spring.
