Kobalt's 50-piece, dedicated 1/4-inch drive mechanics tool set is featured in our new injection molded case with spring-loaded clip. This set is comprised of one (1) 1/4-inch drive ratchets paired with 22 popular metric and SAE 6-point shallow sockets, two (2) 1/4-inch drive extensions (2-in and 4-in), a spinner handle with a bit coupler and twenty-two (22) insert bits. The 1/4-inch drive, 90-tooth ratchet with 4 degree arc swing allows for work in tight spaces. All sockets feature a 6-point design to help prevent slippage and rounding of fasteners. Socket size callouts are hard stamped for easy and long-lasting identification. All tools are constructed from chrome vanadium steel and are heat-treated for strength and durability and finished with a professional grade, high-polish shine which makes cleaning them a snap. Contained in a small injection molded case measuring 6.7in H x 5.0in W x 2.7in D makes carrying this case virtually anywhere possible. Tools meet or exceed ANSI specifications. Tools are covered by Kobalt's Hassle-free Lifetime Guarantee
