saTra wrench set with ratchet S-12GW72 — open-end to box wrenches 8–19 mm (metric)

The saTra wrench set with ratchet S-12GW72 contains combined open-end to box wrenches in metric sizes from 8 mm to 19 mm. Each wrench integrates a ratchet mechanism in the box end, allowing continuous turning without repeatedly removing and repositioning the tool on the fastener. The set is designed for general mechanical and maintenance tasks and fits common automotive, workshop and household applications where access is limited and fast, efficient operation is required.

Advantages

The integrated ratchet saves time by enabling uninterrupted rotation in confined spaces while the open-end side gives quick entry on seized or partially obstructed fasteners. Hardened chrome-plated construction resists wear and corrosion, ensuring consistent torque transfer and long service life. The set covers a practical range of metric sizes that match standard bolt and nut dimensions used in cars, machinery and domestic equipment.

How to use

Select the wrench size that fits the fastener snugly. Engage the open-end for quick placement on partially accessible nuts or bolts; use the box end with the ratchet for continuous turning in confined spaces without lifting the wrench. Reverse the ratchet direction where necessary to tighten or loosen fasteners. Apply smooth, steady force aligned with the wrench to avoid rounding the fastener corners.

Usage recommendations

Inspect wrenches before use for wear and damage; avoid applying impact or excessive torque beyond the tool’s rated capacity. Store the set in a dry place to protect the finish and periodically clean and lightly lubricate the ratchet mechanism for reliable operation.
