What glue or adhesive do you recommend for Type 1 Bonded?

The Type 1 Bonded Fix is made of ABS, which is a relatively good plastic for bonding, and there are many structural adhesives suitable for a wide range of panel materials: e.g. a 2-part structural acrylic adhesive, a matched adhesive for solid surface (Corian®,...

Can I use Button-fix to mount ceiling panels?

Type 1 Fixes may be used to mount ceiling panels quite successfully; using the 'Buttonfix strength testing report' here, and using figures based on the maximum perpendicular pull-out force rather than shear force, we can ascertain a maximum panel weight. For example;...

How do I use the load/strength test report?

For Type 1 Fixes, 'Buttonfix strength testing report' is available here. The figures in the table are for four Type 1 Fixes (in a standard ‘2 x 2’ array) and are already adjusted to give a 1.4 safety factor. These figures are actually the maximum for two Fixes only;...

How do I mark out / set out Button-fix?

On the Type 1 Fix, the two small notches at the top and bottom edge of the Fix are to help marking out: The notches may be used to mark, or line up the centreline of the Fix. By also marking out, and drawing a line through the centre of the screw holes, the centre...

What is the safe loading?

Button-fixes are very strong, but there are too many variables to be specific about a safe loading for your individual application. For thinner panels and low-strength materials like particle-board, the limiting factor dictating the maximum load will be the pull-out...

Can I use Varianta Euroscrews?

The orange Buttons are designed for this purpose and will accept countersunk Ø6.2mm Euroscrews for Ø5mm pilot holes. While both the Type 1 and Type 2 Fixes are not specifically designed for use with Euroscrews, they can function satisfactorily. For instance the Ø6.2mm...

What is the best type of screw fixing for thin panels?

Varianta Euroscrews are useful for giving good strength in thin panels, normally in particleboard. The orange Buttons are designed to accept countersunk Ø6.2mm Euroscrews for Ø5mm pilot holes. While both the Type 1 and Type 2 Fixes are not specifically designed for...

Can I lock/secure panels?

The détente will generally deter accidental displacement; if necessary an aluminium or PVC extrusion, or even a small block may be screwed into the 15mm ‘drop’ gap above the panel, to stop it being lifted. By orienting the Fixes at 90 degrees, panels can be slid in...

Do I have to leave a gap at the top of a panel?

Not necessarily; by orienting the Type 1 Fixes at 90 degrees, panels can be slid in sideways. Adjacent panels can also be mounted similarly, but of course the first panel(s) installed will effectively be locked in place, unless the subsequent panels are removed. This...

Can Button-fixes withstand shock loading?

Type 1 Fixes can carry a significant cantilever load; as a general rule of thumb, it is a good idea to keep the cantilever distance, that is the shelf depth, shorter than the height between the Fixes. In most circumstances, the screws will pull out of the panel before...

When would I use Varianta Euroscrews in the Buttons?

Varianta Euroscrews are useful for giving good strength in thin panels, normally in particleboard. The orange Buttons are designed to accept countersunk Ø6.2mm Euroscrews for Ø5mm (0.197") pilot holes. For more detailed information, including screw length/panel...

Can the gap between panels be zero when using Type 1 Fixes?

Yes, but you will need to machine a stepped rebate for the Type 1 Fix moulding - please ensure that the Fix is not sub surface, otherwise the panel may bind up on installation. Note that if the Fixes are used on the removable panel, the screws holding the Fix will no...

What screws or fixings should I use?

See the ‘Products’ section of the website for recommended fixings, or for more detail download the 'Suggested Fixings for Buttonfix' PDF from the Useful Information page. The limiting factor dictating the maximum load is, in most cases, the pull-out load of the fixing...

Can I use machine screws?

Yes; the lime green countersunk screw Button will accept an M5 countersunk screw. The rebated Fix will accept M4 countersunk screws, while the surface-mounted Fix will accept M4 pan head screws, ideally with washers, or for maximum strength M5 pan head screws,...

Can I space off the Buttons?

Yes, generally using M5 x 25 steel ‘penny’ washers; however, if the Buttons/Fixes are binding due to angular misalignment, it is best to use washers that are within the ‘footprint’ of the Button (i.e. Ø18mm or less, for example part number 1000750000VR here) which...

How do I use Button-fixes on bath panels?

Type 2 Fixes are ideal for mounting bath panels, especially in conjunction with the Type 2 Fix-markers (available on the Accessories page), which remove the need for any measuring. We have made a video, showing a typical bath panel installation. Note that you can get...

How many Button-fixes do I need per panel?

If the load is purely in the vertical plane, then four Button-fixes will usually be sufficient to carry the load of most timber based panels that one person can lift. However, in order to keep the panel flat you may wish to use more Button-fixes. As a rough guide,...

Can I fix Button-fixes to metal structures?

You can use Ø4.8mm pop rivets, with washers to protect the plastic of the Fixes, and/or self tapping screws, but you will need to satisfy yourself of the fixing type and loadings by thoroughly testing the application. Recessing the Fixes into sheet material or tube...

How do I remove panels?

If the surface of the panel is smooth and air tight, use suction panel lifting pads and lift in the direction of the Button-fixes (usually vertical but sideways mounting is possible). If the surface is too rough or corrugated for the vacuum pads to grip, depending on...

Can I fix to plasterboard?

For maximum strength on plasterboard, fixing through to studs or noggings is best. If this is not practical, direct fixing onto the plasterboard is possible, but the maximum loadings must be reduced significantly. The next best option is to attach the Fix to the...

Can I use Button-fix in outdoor applications?

Yes, with the proviso that the Button-Fixes are not subject to direct sunlight (Ultra Violet light will weaken all plastics with age; however in most situations as an ‘invisible fix’, the Button-fix fittings will be shielded from direct sunlight) The Button-fix...

Who are the designers of Button-fix?

Wills Watson+Associates designed Button-fix. They specialise in professional products. You can see their work, from large-scale architectural products to small medical devices, on their...

Can I use Button-fix to fix glass panels or mirrors?

You can bond directly to glass using Type 1 Bonded, although care should be taken to ensure the adhesive used is suitable for whatever finish or surface is present on the rear face of the glass. Another option, especially if using thin glass or mirror, is to bond the...

When would I use Euroscrews in the buttons?

Euroscrews are intended for applications where only a short screw can be used, for example on thin panels. The orange Buttons are designed for Ø6.2mm Euroscrews fixed into a Ø5mm pilot hole.
