## Description

The Wera Tool Check 21 Piece Modular Screwdriver and 1/4" Drive Socket Set Imperial is a compact, versatile 21-piece tool kit designed for both manual and machine-operated screwdriving across a wide range of imperial fastener types. At the heart of the set is the ergonomic Kraftform 815/1 bit-holding screwdriver handle, paired with the Zyklop Mini 4 bit ratchet (8011) for precise, compact ratcheting in tight spaces. A 870/1 adapter converts the 1/4" external hexagon drive to 1/4" external square head, making the ratchet compatible with the four included Zyklop 8790 HMA sockets in imperial sizes. The set includes 9 BiTorsion (BTZ) bits for Phillips, TORX®, slotted, and square head screws, offering flex-zone torsion absorption that helps protect both the fastener and the bit. Four tough Z-series hex bits in imperial sizes round out the bit selection, making this kit ideal for electricians, automotive technicians, and general contractors working with imperial fixings. Housed in the Tool-Check Modular 1 case, this set can be expanded and connected to other Tool-Check Modular components using the rigid 9549 adapter or the flexible 9550 hinge, making it a scalable solution for tradespeople who need a compact yet adaptable toolkit on site.
