مفتاح ربط مركب من ساتا قياس (30mm) موديل (ST40222SC)

Key design highlights include a dual-end setup (open-end and offset box-end), a 30 mm size for large fasteners, chrome vanadium steel for strength, a chrome-plated finish for rust resistance, an ergonomic handle to reduce fatigue, and an anti-slip open-end to prevent rounded fasteners. The offset box-end improves access in confined spaces.

Core specs: size 30 mm; material is premium chrome vanadium steel; finish is chrome-plated for corrosion resistance; dual-end design (open-end and offset box-end); ergonomic handle; anti-slip open-end; compact and sturdy build suitable for heavy-use environments.

With both an open-end and a box-end, you can choose the fastest option for the task at hand. The open-end is handy for quick adjustments and loose fasteners, while the offset box-end provides a secure, higher-torque grip in tight spaces where the open-end can’t reach.

Large-bolt fasteners on equipment like pumps, skid frames, structural mounts, and other industrial assemblies benefit from a 30 mm size. The wrench’s robust construction handles heavy-duty torque, while the offset box-end helps reach fasteners in constricted areas.

Use the correct 30 mm size for the fastener to avoid slipping. Apply steady, even force and avoid using the wrench as a lever or prying tool. After use, wipe off debris, keep it dry to prevent rust, and store it in a dry tool chest. Regularly inspect the chrome finish for chips that could expose the steel to corrosion.

Wear eye protection and gloves when working with large fasteners. Ensure the wrench is fully seated on the fastener before applying torque to prevent slippage. Avoid using the tool on severely rounded or damaged fasteners, and keep hands clear of the path of the handle when applying force.

Yes. It uses chrome vanadium steel with a chrome-plated finish for durability and corrosion resistance, and features precision geometry and an ergonomic handle designed for repeated, professional use in demanding environments.

Measure the fastener across the flats and compare to 30 mm. A snug fit minimizes slippage and reduces rounding. If the fastener is very tight or damaged, avoid forcing the tool; select the correct size or use penetrating oil and appropriate safety procedures.

Wipe the tool after exposure to dust, oil, or moisture. Dry thoroughly to prevent rust, and store in a dry, ventilated area. Periodically apply a light coating of light machine oil to the metal surfaces to maintain the finish and reduce corrosion risk.
