400 RA SHK Kraftform Kompakt 18 Piece T Handle Ratchet Screwdriver Set

The Wera 400 RA SHK Kraftform Kompakt is an 18-piece T-handle ratchet screwdriver set designed specifically for HVAC and plumbing applications, combining precision ratchet mechanics with a versatile bit selection for demanding installation work. At the heart of the set is the 416 RA T-handle bitholding screwdriver, featuring an integrated fine-toothed ratchet with 80 teeth and a 4.5° return angle. This allows continuous screwdriving without repositioning the tool, making it well suited to working in confined spaces or on repetitive fixing tasks common in heating and ventilation installations. The reversing lever enables smooth clockwise and counterclockwise switching in one-hand operation, while the Rapidaptor quick-release chuck accepts standard ¼" bits for fast, tool-free changes. The ergonomic 2-component Kraftform handle is shaped to fill the palm, with softly rounded recessed grips that allow the whole hand to engage the handle — reducing friction loss and fatigue during extended use. A second 816 R bitholding screwdriver with Rapidaptor chuck is also included, extending versatility for straight-on driving alongside the T-handle format. The set covers an extensive range of fastener types relevant to SHK (heating, air conditioning, and plumbing) trades, including Phillips, Pozidrive, PlusMinus, TORX®, slotted, and hex bit profiles, along with two magnetic nutsetters for 8 mm and 10 mm fixings. Everything is housed in a robust textile storage box with a hook and loop fastener strip for organised access on site.
