Designed to provide additional length to help with hard-to-reach areas, the SK Hand Tool 1/4" Drive Semi-Deep Sockets offer a SureGrip Drive design to allow users to drives the side of the fastener, not the corner. This feature provides increased strength and helps avoid rounding of rusted or damaged fasteners. The SuperKrome plating produces a jewelry-like, mirror-polished finish that's highly corrosion resistant to help assure long life. The 1-1/4" long, semi-deep sockets provide added reach over standard sockets, according to the company. Available separately, or in sets, these tools are available in 6-point fractional/SAE and metric sizes.
