One of the biggest reasons that our customers love using the Keep-Nut fastener system is the clean, modern aesthetic that it is key in creating – completely the opposite effect of exposed bolts and hardware that can totally destroy the intended look of a design.

Keep-Nut® is a revolutionary press-in threaded insert that features a highly innovate mechanical anchoring function that creates permanent threads in panels made of marble, granite or other stones, as well as other solid surface materials like glass, HPL, composites, carbon, and many more popular materials.

How Does Keep-Nut Work?

The Keep-Nut fastener is manufactured in stainless steel and consists of a threaded bush, a set of toothed spring washers (crowns), and a plastic ring holding the parts together. Highly customizable for your particular project needs and panel thickness, Keep-Nut is available in different length and sizes, as well as with or without flange. Our customers love the simple and quick Keep-Nut installation process. Simply drill the hole with the correct hole diameter, do a quick check with depth gauge to ensure that the hole is the right size, set up the Keep-Nut fastener and bang it in with a rubber mallet or a hammer.

What Sorts of Applications Are Best for Keep-Nut?

The Keep-Nut insert is specifically developed to fasten ventilated facades, undermount sinks, wall coverings, decor and interiors, furniture, kitchen and sanitary elements, as well as a variety of other applications.

We love seeing our customers put Keep-Nut fasteners to work. Have you seen this video of Keep-Nut being used to install marble trim for a major Fifth Avenue retailer in New York City? Obviously, this design requires the highest quality of hidden fasteners to ensure that this beautiful marble installation is unmarred by unsightly hardware. IN this particular installation Keep-Nut fasteners are being used to attach two pieces of marble with an aluminum angle. Take a look here.

What Are Some of the Most Prominent Benefits of Using Keep-Nut Fasteners?

Keep-Nut inserts have a long list of advantages compared to other fasteners for stone and solid materials. Let’s take a look at just a few.

• Assembly by pressure is quick and easy and does not require the use of any additional resins or adhesives.
• Compatible with thin materials including 2 cm (down to ⅜” depending on variety used)
• Shallow hole depth (<¼”) means less drilling in granite, less wear on bits, and less time on equipment.
• Quick and simple installation.
• Incredible strength (up to an amazing 562 pounds per fastener)
• Works in natural stone, “honeycomb” composite stone, quartz, solid surface, glass and a wide variety of high hardness materials.
