Ratchet Wrench KS Tools 914.3820

The KS Tools 914.3820 ratchet wrench is a hand tool engineered for general mechanical and maintenance work. Constructed from chromium-vanadium steel, the wrench combines strength with a compact, lightweight design, weighing approximately 390 g. It features a 72-tooth ratchet mechanism to allow fine incremental movement and precise engagement in confined spaces. The tool is manufactured to recognized DIN and ISO standards, reflecting consistent dimensional accuracy and drive compatibility.

Advantages

The chromium-vanadium steel construction provides corrosion resistance and high tensile strength while keeping the weight low for comfortable handling. The 72-tooth ratchet head enables small arc swing for incremental tightening or loosening where space is limited. Conformance to DIN and ISO standards ensures interchangeability with sockets and accessories produced to the same norms, and the overall balance of rigidity and control supports repeated use in workshop and field environments.

Suitable for

• Automotive repair and maintenance
• General mechanical assembly and disassembly
• Workshop and industrial maintenance tasks
• Tightening and loosening fasteners in confined or awkward spaces

Key specifications

• Material: Chromium-vanadium steel
• Ratchet mechanism: 72-tooth head for fine incremental movement
• Weight: approximately 390 g for one-handed handling
• Standards: manufactured to DIN 3120, ISO 1174, DIN 3122, ISO 3315 specifications
• Drive arrangement: compatible with standard socket drives produced to the same norms

How to use

Select a socket that fits the fastener and attach it securely to the ratchet drive. Set the ratchet direction selector to the desired rotation for tightening or loosening. Operate the wrench with steady controlled strokes, using the 72-tooth ratchet to make small-angle movements where clearance is limited. Avoid applying excessive force beyond the expected torque limits of the tool and the fastener; use a torque wrench when specified torque values are required.

Usage recommendations

For long service life, keep the ratchet mechanism clean and periodically lubricate according to workshop practice. Inspect sockets and the drive interface for wear before use, and avoid impacts or misuse that can damage teeth or compromise fit. Where precise torque is required, follow the fastener manufacturer’s torque specifications and use a calibrated torque tool.
