SATA GL81108A Long Ball Point Hex Key 4mm

The extended shaft length improves leverage and allows you to reach fasteners that standard keys cannot, reducing strain and making turning smoother in confined spaces.

The ball point tip allows angled entry, so you can engage fasteners at non-perpendicular angles without stripping the head or needing perfect alignment.

It’s made from chrome vanadium (Cr-V) alloy steel for strength and durability, and it’s coated to resist corrosion and wear for longer tool life.

Recommended for automotive fasteners, electronics assemblies, and general repair tasks where access is restricted or space is tight.

Select the correct 4mm size, ensure the tip seats securely with a light chamfered edge, approach the fastener at a comfortable angle, apply steady pressure, and use controlled torque to prevent slipping or rounding.

Look for the 4mm size marking on the tool, ensure the tip engages the fastener squarely, and confirm there is no wobble or slipping before applying torque.

Wear eye protection when working in tight spaces, keep a firm grip to prevent slipping, avoid using the tool as a pry bar, and store it in a dry place to preserve the coating and tip integrity.
