Ratchet wrench set wiha 45244, 8-piece, sizes 8–19 mm

The wiha 45244 ratchet wrench set is an eight-piece collection of ring ratchet wrenches covering metric sizes 8–19 mm. Each wrench features a closed-ring head with a ratcheting mechanism designed to tighten and loosen hex fasteners efficiently. The compact range of sizes and the ratcheting action make the set suitable for both professional workshops and general maintenance tasks where reliable torque transfer and quick operation are required.

Advantages

The set provides a continuous ratcheting action that reduces the need to reposition the tool during repetitive fastening operations. Precision-machined ring heads ensure secure engagement with hex fasteners, minimising slippage and rounding. A compact profile allows access in confined spaces while the graduated size range from 8 to 19 mm covers the most common bolt and nut dimensions used in automotive, assembly and repair work.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Equipment servicing and installations
• General household repairs and DIY projects

Key specifications

• Number of pieces: 8
• Wrench type: ring ratchet wrench
• Sizes included: 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 19 mm
• Drive action: ratcheting mechanism
• Material: hardened steel (engineered for strength and wear resistance)
• Finish: corrosion-resistant surface treatment

How to use

Select the correct wrench size to match the hex fastener and fit the ring head fully over the nut or bolt. Set the ratchet direction if the wrench offers a reversible mechanism, then apply steady torque while operating the ratcheting action to tighten or loosen the fastener. For confined spaces, use the compact profile and small increments of motion to engage the ratchet without stripping the fastener. Inspect fasteners and threads before applying high torque to avoid damage.

Usage recommendations

Use the appropriate size from the set to prevent rounding of bolt heads. Keep the ratchet mechanism clean and occasionally lubricate pivot points to maintain smooth action. For high-torque requirements, use a torque-calibrated tool as needed and avoid excessive force that could damage the wrench or fastener.
