Wera 8790 HMA Deep 1/4" Drive Hexagon Socket Metric 1/4" 4mm

The Wera 8790 HMA Deep 1/4" Drive Hexagon Socket in 4mm is the smallest in the range, making it particularly well suited to precision fastening tasks where compact bolt heads are involved, such as electronics, instruments, or fine mechanical assemblies. The deep profile and 50mm length allow it to reach low-lying fasteners and work around protruding threaded rods with ease. The hexagonal profile ensures high power transmission while protecting delicate fastener edges — essential when working with smaller fixings that are more susceptible to rounding. A ball intercept ring keeps the socket securely seated during both hand and machine operation (non-impact). Wera's Take it easy colour-coding system makes identifying the 4mm socket in your kit fast and straightforward. Knurling on the lower end provides grip security even in oily conditions.
