مفتاح ربط ساتا للإنشاءات قياس (17x21mm) موديل (GL47310)

Key specs include a dual-sized head (17 mm / 21 mm), a fine-tooth ratchet for smooth operation, a chrome-vanadium steel construction, a chrome-plated finish for corrosion resistance, and an ergonomic, non-slip handle. The compact design is tailored for tight spaces.

The ratchet mechanism lets you turn fasteners with continuous rotation without removing the wrench from the fastener, which speeds up repetitive tasks and improves efficiency in tight or confined spaces.

It’s well suited for construction, automotive maintenance, equipment repair, and any job that requires fastener access in tight spaces. The dual 17/21 mm sizes also make it versatile for a range of hardware without swapping tools.

Steps: (1) Identify whether you need 17 mm or 21 mm, (2) set the wrench to the appropriate opening, (3) engage the fastener and operate the ratchet in the desired direction, (4) if needed, use the tip end for light wire twisting, (5) switch directions as required and avoid over-torquing.

Keep it clean and dry after use, wipe away debris, and dry thoroughly to prevent corrosion. Periodically apply a light machine oil to the ratchet mechanism and moving joints, and store in a dry toolbox to maximize longevity.

Compared with single-size wrenches, this dual-size model reduces tool swaps and saves time on multi-size tasks. It also consolidates two functions into one compact tool, which helps reduce tool clutter.

Yes. It is engineered for heavy-duty use with a durable chrome-vanadium steel body and a fine-tooth ratchet mechanism designed to handle demanding construction tasks while maintaining smooth operation.

Wear appropriate eye and hand protection, ensure the workpiece is stable, and avoid using the wrench with damaged fasteners. Use the correct size for the fastener to prevent rounding edges, and keep hands away from moving parts during operation.

Yes. Inspect for cracks or excessive wear, verify the dual heads are clean and free of debris, and check the ratchet mechanism for smooth engagement. Lubricate the pivot points lightly if stiffness is noticed, and replace if any part appears damaged.
