HILTI Powder-Actuated DX 2 Fastening Tool

By Robert Robillard on Tools PLUS!

Power actuated tools are well known on the jobsite as a fast, safe and cost effective way to fasten materials to concrete.

Often referred to as a “Hilti gun or a Ramset gun” these tools have been a go to for direct fastening and the technology works on a controlled explosion created by small propellant cartridge charge, similar to the process that discharges a firearm.

Powder-actuated technology was developed for commercial use during the World War Two, to repair a hull breach in navy ships by attaching metal plates over the holes.

HILTI Powder-Actuated DX 2 – Fastener Range

The HILTI Powder-actuated fastening tool DX 2 was built to accommodate pins ranging from 1/2 in. to 2-1/2 in. and also a  2-7/8 in. nail with a pre-mounted washer.

The 0.27 caliber loads in strips of 10 and a Semi-automatic cartridge advances the strip automatically when the tool is cycled.

Sold in a carry case with the tool, stabilizer, cleaning kit, spares pack, lubricant we found the HILTI Powder-Actuated DX 2 compact, durable, easy-to-use and able to install fasteners safely and rapidly.

At 5.3 pounds, the HILTI DX2 is compact and its durable aluminum body gives you long service life, access to those hard-to-reach corners and improved ergonomics.

Fastener Cartridge

The HILTI cartridges are called Clean-Tec, which means they contain no lead or other heavy metals, meaning they are environmentally-friendly.  They come in different strength charges  and are color coded:

  • level Green
  • 3,Yellow
  • 4, Red
  • 5

Numbered strips help you to use the full cartridge, reducing waste and saving costs.
