MEMFast launches new patented Rivet Nut Hand Tool
The new RNHT48 Rivet Nut Hand Tool has just been launched by MEMFast (Make Ends Meet Limited). Packed in a tough but attractive aluminium case with individual foam cut outs for each component, the patented tool can be assembled and ready to use in seconds.
T
his very robust tool, made in the UK, offers great flexibility – it installs M4 to M10 rivet nuts in steel, stainless steel, aluminium and brass by using a simple ‘spin’ action. MEMFast highlights that there is no stroke to set, it is much tougher and easier to use than conventional hand pliers and is much
more compact than lever type tools. “In terms of the combined benefits of design quality, component durability, ease
of assembly and use, the RNHT48 could realistically be described as one of the best rivet nut hand tools available.” The mandrels are standard 12.9 grade socket head cap screws – that can be sourced
anywhere and, if worn or broken, changed very quickly. Spare mandrels are included with the tool. The main components have zinc nickel silver plating which will provide up to 4,000
hours salt spray resistance, and the outer bodies and inner hex screw drives are case hardened for long life. A 10mm ratchet spanner is included with the tool to assist with installation of larger
sizes of rivet nuts and a special hex allen key is also provided to enable extraction of a worn or broken mandrel. The UK and European versions of the tool will have metric mandrels – those for
the USA and Canada will have UNC as standard with metric conversion kits available. Because of its “spin” action, MEMFast says that the RNHT48 is ideal for use with
not only sheet metal but also plastics, GRP and composite materials. The existing RNHT07 Rivet Nut Hand Tool with the gold knob will continue to be
sold alongside the new tool for customers who only need to install specific sizes of rivet nut, for example M6.
New clinching tool delivers
International fastening and assembly technology specialist Böllhoff has developed a new fastening tool which it says enables class D airtight air duct flanges to be manufactured significantly faster, cleaner and more economically than traditional drill and fix methods.
in a single operation. No additional fastener components are required, there is no swarf and hence no waste. Key to the success of RIVCLINCH®
C alled RIVCLINCH® 0404 IP Aero the tool is TÜV NORD certified for class D
and produces cold formed airtight joints in cycle times of between 0.9 to 1.5 seconds: which Böllhoff points out is less time than it takes to drill a hole. The robust, pneumatically operated tool achieves low cost, high quality, joints
and the class D joint it achieves is its tooling
which is designed to penetrate the top and bottom layers of each joint while leaving a middle layer in tact to prevent air leakage. The process delivers high strength, interlocking joints which do not vibrate or work loose over time. The clinching tool is easy to use. Jaws are opened either manually or pneumatically
and positioned along the profile. A trigger is pulled to deliver a clinching force of 35kN. Distances between fastening points are generally between 120mm and 160mm. Weighing in at 4.7kg the clinching tool requires 5 to 6 bar air pressure supply. The RIVCLINCH®
technique can be used to join steel and stainless steel sheet as
well as aluminium and other non-ferrous materials. Coated and prefinished materials can also be joined together without surface damage. “Advantages of the RIVCLINCH®
process include no consumable items, low energy
use, absence of thermal load and damage to work pieces, option to use interim layers of film or adhesives, no pre or post treatments, excellent repeatability and environmental credentials – no heat, fumes and low noise.”
