KTC TB310 3/8" Metric Socket Set 10 pieces

The KTC TB310 is a 10-piece hex (6-point) socket set designed for strong, reliable grip and reduced fastener damage. These sockets feature KTC’s Powerfit design, which improves how the socket contacts the nut or bolt head.

Unlike ordinary sockets that tend to load force into the corners, Powerfit spreads the load across a broader contact area, helping reduce stress on the edges of the fastener. This makes it less likely to round or damage bolt heads, especially when working with tighter or higher-torque fasteners.

The set also includes the KTC EHB310 socket holder, designed to keep all 10 sockets organised and easy to access. The holder is magnetic, so it can stick securely to metal surfaces like toolbox lids or cabinets, and it also features pre-drilled holes for permanent screw mounting, giving flexible options for both mobile and fixed workshop setups.
