مفتاح ربط مزدوج الطرف من ساتا قياس (13/16") و (7/8") موديل (GL42105)

The 40° offset allows you to approach fasteners that are tucked into tight or awkward spaces, giving you better leverage and angle without banging into nearby components.

Off-corner loading shifts load away from the sharp corners of the fastener, providing a more secure grip, reducing the chance of rounding, and improving torque transfer during use.

The wrench is constructed from chrome vanadium steel and finished with a corrosion-resistant chrome coating. This combination offers durability, wear resistance, and rust protection for heavy-duty use.

Key features include dual-box ends (13/16" and 7/8"), laser-etched size markings for quick identification, a slim head for tight spaces, an ergonomic non-slip grip, lightweight construction, and precisely engineered box ends for a snug fit.

This wrench is well-suited for automotive work, machinery maintenance, bike and motorcycle repair, and any task requiring access to fasteners in cramped areas where a standard wrench or ratchet may not fit.

Use the correct size for the fastener to avoid rounding. Keep the wrench clean and dry after use, store it in a toolbox, and avoid using it as a lever or hammer. Apply light lubrication to moving metal surfaces if needed and wipe away any grit or debris.

The sizes are laser-etched on the wrench, allowing for fast and unambiguous identification between the 13/16" and 7/8" ends.

Both are dual-box end wrenches from the SATA family and share the concept of two sizes in one tool. GL42104 is another option in the same line and may differ in the exact sizes or geometry. See the product page for GL42104 for exact specifications: https://fepy.com/products/sata-gl42104-double-box-end-wrench-13-16-x-7-8

GL42106 is another dual-box end option in the SATA lineup and may differ in size pairing or head geometry. For the precise details and to compare side-by-side, view its product page: https://fepy.com/products/sata-gl42106-double-box-end-wrench-13-16-x-7-8

Box-end wrenches are designed to distribute torque across the contact surfaces and resist rounding when used with the correct fastener size. Ensure you select the right end (13/16" or 7/8"), apply steady pressure, and avoid using the tool as a pry bar or hammer. Wear safety glasses if needed and keep hands clear of pinch points.

Yes. Having both 13/16" and 7/8" ends in one compact tool reduces the number of individual wrenches you need to carry, saves space, and provides versatile access in tight or recessed areas without compromising on grip or torque efficiency.
