مفتاح ربط متري ذو طرفين مغلقين قياس (5.5mmX7mm) موديل (ST42221)

The 40° offset provides extra clearance and leverage, making it easier to reach fasteners that sit at awkward angles or are blocked by nearby parts.

Off-corner loading means the wrench jaws engage the fastener on a corner rather than the flat face, which improves grip, reduces rounding, and helps apply torque more securely.

It is made from high-quality steel with a corrosion-resistant chrome plating to extend life and resist rust in demanding environments.

Compact and slim profile, precise box-end fit, laser-etched size markings, and an ergonomic, non-slip handle all contribute to easier handling in confined areas.

Ideal for automotive, bicycle, appliance, and machinery maintenance where fasteners are small-to-mid sized and located in tight or awkward spots.

Engage the correct size fully on the fastener, apply steady torque straight along the fastener axis, avoid using the wrench as a pry bar, and keep hands clear of the fastener to minimize slippage.

The sizes are clearly marked with laser-etched markings on the wrench head for quick identification during work.

Compared with open-end wrenches, this tool offers a tighter, more secure grip in restricted spaces. Compared with standard box-end wrenches, the offset and off-corner design provide better reach and reduced fastener rounding in awkward positions.

Yes. The combination of durable steel, precise fit, and corrosion-resistant finish makes it well-suited for professional settings where reliable torque and access are required.

Keep it clean and dry after use, wipe away any debris, store in a dry environment, avoid exposing it to corrosive substances, and inspect for wear or rounding before each use.
