3/8 Inch Drive Shallow 6-Point Universal Joint Impact Socket Set with Rails and Tray, 21-Piece (5/16 - 3/4 in., 8 - 19 mm)

• 30-Degree Working Angle – The joint rotates smoothly and continuously at up to a 30-degree angle • 6-Sided Pinless Joint – Our solid ball-and-socket style joint is stronger than joints that use pins, and the 6-sided ball operates more smoothly than 4-lug designs • Two Size Markings – The size is marked with a high-visibility laser marking and a permanent stamped marking • Works With Friction Ring or Detent Pin Anvils – Smooth walls inside the drive end and a detent pin hole make the sockets compatible with both drive tool anvil types • Socket Organization Rails and Tray – The twist-to-lock clips on the rails hold sockets securely and can be repositioned anywhere along the rail
Tekton Universal Joint Shallow 6-Point Impact Sockets have a compact design for tight spaces. The joint of the socket rotates smoothly and continuously at up to a 30-degree angle. Our solid ball-and-socket style joint is stronger than joints that use pins. The 6-sided ball operates more smoothly than 4-lug designs. The socket base is made from 4140 chromium-molybdenum steel, and the ball/socket piece is made from 8660 nickel-chromium-molybdenum steel. Both pieces have a corrosion-resistant manganese phosphate coating. The socket comes pre-lubricated with SuperLube Multi-Purpose Synthetic Grease (NLGI 2) with Syncolon (PTFE). Maintain the lubrication using this grease or a comparable grease as needed to reduce wear over time. The 6-point socket opening provides an exact fit and maximum contact for hex fasteners. Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners. The socket size is marked in two ways on every socket—both as a high-visibility laser marking and a permanent stamped marking. Smooth walls and a detent pin hole allow the socket to work with both friction ring and detent pin anvils. This set includes socket organization rails and a tray. The twist-to-lock clips on the rails hold sockets securely and can be repositioned anywhere along the rail. To release the rails from the tray, press the button beside the keyhole latch and slide the rail out.
