مفتاح سداسي من ساتا قياس (14mm) مطلي بالأكسيد الأسود موديل (ST84320SC)

Material: chrome vanadium alloy steel (Cr-V). Finish: black oxide for durability and corrosion resistance. Size: 14mm. End design: chamfered ends for smooth insertion. Readable markings for quick size identification. It’s lightweight for comfortable extended use.

The black oxide finish enhances durability and corrosion resistance, helps resist wear in tough environments, and can improve grip in oily or greasy conditions while still allowing the size markings to remain legible.

This listing is for a single 14mm hex key—not a set.

It's suitable for automotive work, construction tasks, and general maintenance where a 14mm hex fastener is used, especially in tight spaces where a compact tool is beneficial.

Align the hex key with the fastener head, apply steady, medium torque, and avoid sudden twists or impacts. Use a handle or guided tool for better leverage and control, and never use it as a pry bar or screwdriver.

Wipe the tool after use, ensure it’s dry, and apply a light coat of oil to prevent rust. Store it in a dry toolbox or designated tray to keep it protected and easy to locate.

Two comparable options available on Fepy.com include: - SATA ST84322SC 15mm Black Oxide Hex Key — https://fepy.com/product/sata-st84322sc-15mm-black-oxide-hex-key - SATA ST84310SC 12mm Black Oxide Hex Key — https://fepy.com/product/sata-st84310sc-12mm-black-oxide-hex-key Differences to note: size (15mm vs 12mm), which affects which fasteners you can service; finish and Cr-V construction are similar, but size and reach will influence usability in tight spaces and torque application.

This is a standalone hex key designed for use by hand or with a handle/driver that accepts hex keys. For leverage, you can attach it to a suitable T-handle or ratchet-adapter that accepts hex-key inputs, keeping within safe torque limits.

Wear eye protection if there's a risk of debris, ensure your hands are dry for a solid grip, confirm that you’re using the correct size to prevent rounding the fastener, and keep the tool away from children. Use steady, controlled force and stop if the fastener doesn’t seat properly.

Its combination of Cr-V steel, durable black oxide finish, chamfered ends for easier insertion, clear size markings, and compact, lightweight design makes it a reliable, budget-friendly choice for everyday use in automotive, construction, and general maintenance tasks.
