Ampco WH-3MM Metric Hex Key 3 mm

The Ampco WH-3MM is a non-sparking, non-magnetic metric hex key built for maintenance in hazardous environments. Its corrosion-resistant, unfinished construction suits professionals who need a tool that will not ignite flammable atmospheres. The 3 mm tip fits standard metric fasteners. Two tips on the L-shaped body give a long reach and a short leverage option.

Suited for hazardous-area maintenance.

Mechanics and plant engineers working near fuels, solvents or dust benefit from the non-sparking and non-magnetic properties. The short 20 mm arm and long 63 mm arm cover tight and deep access points. Buyers who need a tether-ready tool for drop-prevention policies should look elsewhere. The key is not insulated, so it is unsuitable for live electrical work.

3 mm tip with 63 mm long arm and 20 mm short arm

The single specification that decides fit is the 3 mm metric tip combined with the 63 mm long arm and 20 mm short arm. Verify the fastener size and the clearance available at the job site. If the recess is deeper or the fastener larger, this key will not engage. No other dimensions determine compatibility.

Questions about this item

Should I choose the 3 mm hex key or a different tip size?

This tool has a fixed 3 mm tip size and 63 mm long arm, so choose it only when the fastener requires exactly 3 mm.

What does the 63 mm long arm length mean when I am turning a bolt?

The 63 mm long arm gives extra reach and leverage, while the 20 mm short arm fits tighter spaces.

Does the non‑magnetic, non‑sparking construction limit the environments where I can use it?

No — non‑magnetic and non‑sparking properties make it safe for explosive or sensitive electronic areas.
