Wera Range of 8790 HMB Deep 3/8-inch Hex, Individual Sockets - Wera 05004535001, The Wera 8790 HMB Deep 3/8" socket 13 x 64mm is a long 3/8" hand and machine socket (ISO 2725 part 3) with ball intercept ring; for external hexagonal bolts and sockets.For use in manual and machine operation (non-impact), even with low-lying screwdriving and protruding threaded rods. With Take it easy tool finder with colour coding by size - for quick and easy location of the required tool. Slip-proof for easy grip, even with oily hands. The hexagon profile allows the transmission of high forces and puts less strain on the edges of bolts or screw heads than a double hexagon profile. Fine-toothed ratchets make the use of a double hexagon profile superfluous, even in confined spaces, due to their small return angle.The long design of the socket allows screwdriving to be achieved where space is limited, and the knurled lower end provides more grip when used manually.
