SATA GL81107A Long Ball Point Hex Key 3mm

Key specs: 3mm hex tip; extended reach for difficult access; ball-point tip for angled insertion; chamfered tips for easy start; made from chrome vanadium steel (Cr-V) for strength and durability; corrosion-resistant coating to extend life; ergonomic handle for comfortable use.

Choose the long ball point hex key when you’re working in deep cavities or tight angles where a standard short key won’t reach. The extended shaft provides more leverage, and the ball-point tip lets you start the fastener even if the alignment isn’t perfect, saving time in automotive, machinery, or electronics work.

Use the correct 3mm size for the fastener to avoid rounding. Apply steady, even torque rather than quick, jerky movements. After use, wipe off oils and dust, store in a dry spot, and lightly oil the tip if you expect exposure to moisture to maintain corrosion resistance.

Yes, when used with the correct size and proper technique. The Cr-V steel provides strength, and the coated surface helps resist rust in typical workshop environments. Avoid excessive torque and never use a damaged tool on fasteners.

Compared with similar SATA long ball point keys on Fepy, the GL81107A offers the 3mm size with extended reach and a ball-point tip for angled entry.

The long shaft increases leverage, making it easier to turn stubborn fasteners with less effort. The ball-point tip allows entry at an angle, reducing the need to perfectly align the fastener, which is especially helpful in cramped engine bays, electronics housing, or appliances where straight access isn’t possible.

With Cr-V steel and a corrosion-resistant coating, the tool is built for durability. To maximize life, store it dry, avoid overtightening, use the correct hex size for each fastener, and wipe away debris after use to prevent corrosion and wear.

It’s well-suited for automotive work (engine bay fasteners, brackets), electronics enclosure assembly, appliance repair, and general maintenance tasks where a standard hex key won’t reach or you need some extra leverage.

Yes, it combines extended reach, a ball-point tip for angled access, chamfered tips for easy insertion, and durable Cr-V construction, all in a single 3mm hex key. These features typically found across the SATA long-ball-point range make it a versatile, long-lasting choice for the price.
