Metric Hex Key for Non-Sparking Work

This Ampco hex key is a 14 mm metric hand tool made from beryllium copper. It is designed for environments where sparking or magnetic interference must be avoided. The key features a natural finish and two tips for turning metric fasteners. It is suited for maintenance tasks in hazardous or sensitive locations.

Replaces Standard Steel Keys in Hazardous Areas

Standard steel hex keys can produce sparks or retain magnetism, which this tool avoids through its beryllium copper construction. The upgrade is worth it when working near flammable vapours, dust or sensitive electronic assemblies. It also resists corrosion without requiring an insulated coating. The long arm measures 140 mm and the short arm 57 mm for leverage and access.

Handles 14 mm Metric Fasteners with Two Arm Lengths

The key comfortably turns 14 mm metric bolts and set screws using either the 140 mm long arm for torque or the 57 mm short arm for confined spaces. It runs out when a larger or smaller tip size is required, as this model provides only the single 14 mm dimension. The tool is not tether ready, so a separate retention method is needed for work at height.

Questions about this item

What are the arm lengths of the 14 mm hex key?

The long arm measures 140 mm and the short arm measures 57 mm.

How is the hex key used and what common mistake should be avoided?

Insert the 14 mm tip fully into the fastener and turn using the long arm for leverage; do not use the short arm for high torque as it can round the fastener.

Does the beryllium copper hex key need any special maintenance?

The material is corrosion resistant and non-magnetic; wipe clean after use and store dry to preserve the non-sparking properties.
