Hand tool for rivet nuts and studs

MEMFast is promoting the use of its hand tool for the installation of rivet nuts and studs.

"Not only are we seeing potential for the use of the tool by small users in sheet metal, boat building, etc. but also with larger companies", says sales manager Charlton Seal.

"Wagon, a large automotive subcontractor, uses it to rectify the position of rivet nuts that have not been installed correctly. These 'spinners' can be very expensive to rectify if a component is delivered to a customer and a screw cannot be inserted. Usually, the whole batch of work would be rejected but now, using the MEMFast tool, Wagon has found that rejection costs have fallen significantly."

A particular growth area in which interest is growing is from builders of kit cars. "This is due to its ease of use, robust build and design, and accessibility into very tight areas", explains Charlton Seal. "The tool is capable of installing rivet nuts from M3 to M10 and rivet studs from M4 to M8. Each size of fastener has its own 'installation kit' comprising collar and screw. All fastener materials, including steel and stainless steel, can be accommodated."

The action of the tool is described as spin/spin. A user attaches the correct screw to the end of the spindle, inserts it in to the barrel, tightens the plastic nut in to the barrel, and connects the outer nose-piece. If extra torque is needed a standard open-ended or ring spanner can be attached to a 10mm hexagon drive protruding from the tool's knurled knob.
