Wera Kraftform Kompakt 838 RA-R M Ratcheting Screwdriver Set Faster at Every Fastener Wrenching on bikes means a lot of fasteners in a lot of tight spots, and constantly repositioning a standard screwdriver kills your rhythm. The Kraftform Kompakt 838 RA-R M solves that with a ratchet mechanism built directly into the handle. The 36-tooth ratchet drops the return angle to 10 degrees, so you can drive in cramped spots without lifting and resetting the tool. When a fastener spins freely, the ratchet lets you twirl the driver like a pen to run it down fast. The Rapidaptor quick-release chuck swaps bits without tools and locks automatically the moment the bit contacts the screw. Thirteen 89mm bits cover Phillips, Pozidriv, TORX, hex socket, and slotted profiles, so the set handles the full range of fasteners you'll encounter on a modern drivetrain, cockpit, or derailleur hanger. Features 36-tooth ratchet integrated in handle 10-degree return angle lets you drive fasteners in tight spaces without repositioning the tool Rapidaptor quick-release chuck accepts 1/4" hex bits per DIN ISO 1173-C 6. 3 / E 6. 3; locks automatically on contact with the screw, no sleeve manipulation needed Kraftform Plus handle dual-zone construction with hard zones for fast spinning and soft zones for grip during high-torque passes 13 chemically nickel-plated bits, 89mm length Phillips, Pozidriv, TORX, hex socket, and slotted profiles for broad compatibility across bike-specific fasteners | Wera | Kraftform Kompakt 838 Ra-R M Ratcheting Screwdriver Set 15 Pieces
