SKU CH-1AC7-6H1ZT

A non-sparking, non-magnetic hex key with 13 mm tip and 135 mm long arm for HVAC work

  • Non-sparking hex key prevents ignition in hazardous areas
  • Non-magnetic design avoids interference with sensitive equipment
  • Corrosion-resistant finish extends tool life in tough conditions
  • 13 mm tip fits metric fasteners securely
  • Compact 135 mm length provides leverage in tight spaces

HVAC hex key 13 mm

This 13 mm metric hex key is designed for HVAC control work where non-sparking and non-magnetic tools are required. The unfinished finish and corrosion-resistant construction suit maintenance tasks in sensitive environments. It provides two tips for standard hex fasteners.

Thermals noise and power draw

As a hand tool the hex key produces no heat, noise or electrical draw during use. Its non-sparking property reduces ignition risk in areas where flammable vapours may be present. The non-magnetic body avoids interference with sensitive instruments.

Deciding specification 13 mm tip

The 13 mm tip size determines whether this key fits the fasteners on the job. Buyers who need a different hex size or a tether-ready tool will have to select another model. The long arm measures 135 mm and the short arm 51 mm for leverage in tight spaces.

Questions about this item

How do you fit the 13 mm hex tip onto a fastener without rounding the corners?

Engage the full 13 mm tip depth on the bolt before applying torque; the short 51 mm arm gives leverage in tight spots but can slip if not seated squarely.

What part of this tool wears out first and needs replacement?

The unfinished hex tips will gradually round off after repeated high-torque use; once the 13 mm flats no longer grip, the key must be replaced.

At what point does the short arm become the limiting factor during sustained tightening?

The 51 mm short arm reaches its torque limit before the 135 mm long arm, so prolonged force on stubborn fasteners will stall at the shorter lever.
