An insertion force to be reckoned with

01 July 2008

Bollhoff Fastenings has introduced a pneumatic setting tool, which will help many assemblers who use blind rivet nuts to install a reinforced thread in sheet metals, profiles and hollow sections. Now using automatic force-control when ‘pulling-up’ the fastener from one side of the workpiece, the new design is pressure sensitive on the tool stoke to ensure a consistent setting even when the material thickness is variable.

The new P2007 is a stylish, ergonomic hand-held tool, operated by a single trigger movement and engineered for speed and reliability. Once set-up for a given thread diameter (M3-M10 sizes are covered), the installer can set as many as fifteen ‘RivNut’ blind rivet nuts in a minute. The tool is actually capable of setting an M10 stainless steel RivNut with a force of 17kN.

A novel ‘twist-to-set’, colour-coded pressure regulator, enables the P2007 to be set for a different diameter blind rivet nut with considerable ease. The operator simply winds the adjuster to the appropriate colour band, whereupon an auto-mount feature senses contact with the end of the mandrel and quickly spins the rivet nut up against the anvil.

On setting, the operator maintains pressure on the trigger throughout the cycle, to achieve totally consistent results. All that’s required is a pneumatic supply of 5-7bar (the air supply can be connected to either side of tool, depending on operator preference), with each cycle using eight litres of air.

Well balanced, with a soft-feel grip, the P2007 weighs only 2.0 kg without the nosepiece assembly and operates at a noise level of less than 65dBA. The aluminium-bodied tool is fitted with a rubber boot on its base to avoid metal-to-metal contact when resting it on the workbench. The 360 degree air input connector is now at the side of the tool, rather than the front, where access to the workpiece might otherwise be compromised and inadvertent contact cause damage to cosmetic surfaces.

The P2007 is purposed designed to withstand the rigours of use, whether hand held, suspended from a spring balance or within an optional vertical-mount kit.
