Fix It. First Time.
Engineered for Concrete & Steel.

Powder-actuated tools (PAT) use a blank cartridge to fire a pin into concrete or steel — they are powerful and suited to heavy-duty structural fixings. Gas-actuated tools like the Spit Pulsa use a gas fuel cell and battery ignition for lighter, faster operation — ideal for high-volume MEP fixings such as cable trays, conduit clips and pipe brackets.

It depends on the load and substrate condition. For light to medium loads, Tapcon self-tapping concrete screws are the fastest option — no plugs required. For heavy structural loads, use mechanical expansion anchors or chemical resin anchors. For cracked concrete or seismic zones, specify ETA Option 1 approved anchors. Always check the design load tables.

Fire-rated fixings are anchors and fasteners tested to maintain structural integrity during a fire for a specified period (typically 30, 60, 90 or 120 minutes). They are required wherever fixings penetrate or support fire compartmentation — fire barriers, fire-stopping around service penetrations, and structural connections in fire-rated zones. Spit's Tapcon HFL and anchor range includes fire-rated options.

ETA (European Technical Assessment) is an independently verified performance certificate for construction products. An ETA-approved anchor has been tested under controlled conditions for pullout resistance, shear capacity, cracked concrete performance and fire rating. It is required for structural and safety-critical fixings and allows engineers to specify with confidence.

Yes. The Spit Pulsa 800E is designed for fixing into both concrete and steel substrates. Use the correct pin type for each substrate — HC6 pins for concrete and steel-specific pins for metal decking and steel framing. Always check the maximum steel thickness in the technical data for your chosen pin.
