مفتاح سداسي ساتا مطلي بالأكسيد الأسود قياس (16mm) موديل (GL84321)

Key specs include a 16 mm hex tip, chrome vanadium (Cr-V) steel, a durable black oxide coating for corrosion resistance, chamfered tips for fast insertion, clearly marked size for quick identification, an optimized length for smooth rotation, ergonomic design for comfort, and impact‑resistant construction.

Ideal for automotive tasks, machinery maintenance, and various home improvement projects where a 16 mm hex fastener is used.

Select a fastener of 16 mm size, align the hex key with the fastener, apply steady torque in the direction to tighten or loosen, and avoid sudden over‑torque to prevent damage. The chamfered tip helps with quick insertion and the ergonomic handle provides a comfortable grip.

Keep it clean and dry, lightly oil if needed to prevent rust, avoid bending, and store it in a dedicated tool drawer or pouch to protect the tip and maintain its markings.

Compared with other sizes like 13 mm or 20 mm hex keys on Fepy, the 16 mm varies in tip size and torque capacity. For example, the 13 mm variant offers a smaller head for tighter spaces, while the 20 mm variant handles larger fasteners.
