Tool Check 21 Piece Modular Screwdriver 1 4" Drive Hexagon Socket Set

The Wera Tool Check 21 Piece Modular Screwdriver and 1/4" Drive Hexagon Socket Set is a compact, versatile 21-piece kit designed for both manual and machine-operated screwdriving across a wide range of fastener types. At the heart of the set is the Kraftform 815/1 bitholding screwdriver, paired with the 8011 Zyklop Mini 4 bit ratchet — a compact 1/4" ratchet that accepts both bits and, via the included 870/1 adapter, 1/4" square drive sockets. This combination makes the set equally capable whether you're working by hand or with a machine driver. The 13 included BiTorsion (BTZ) bits cover Phillips, Pozidriv, TORX®, slotted, and hexagonal socket fasteners in both 25 mm and 50 mm lengths. The BiTorsion design provides a torsion zone that absorbs peak torques, extending bit life compared to standard bits. Four Zyklop 8790 HMA sockets in 7, 8, 10, and 13 mm round out the set for nut and bolt work. The set is housed in the Tool-Check Modular 1 case, which can be connected to other Tool-Check Modular components using the rigid adapter 9549 or flexible hinge 9550, allowing tradespeople to build a customised, expandable tool system to suit their workflow. Ideal for electricians, joiners, and general contractors who need a compact multi-fastener solution on site.
