Our customers have long been aware that Keep-Nut by Specialinsert is a trusted brand that has been the perfect answer for an anchoring system in countless projects. But residents and travelers who will enjoy the visitors center and museum (set to open in July 2018) at the Gateway Arch in St. Louis, MO will soon see – or more accurately – not see the Keep-Nut press-in insert at work all over the project. (Upon proper installation, it’s an invisible system after all.)

One of the project managers for this huge project told us, “we are using your Keep-Nut (inserts) to attach unistrut to Caesarstone Quartz panels and hanging them from the ceiling and walls in the St. Louis Arch.” And he was kind enough to send along a few photos of how the Keep-Nut by Specialinsert is being put to work.

More About Keep-Nut

The Keep-Nut inserts are threaded self-anchoring fixing systems for marble, stone, ceramic, artificial stones, sandtones, klinker, laminated HPL.

The Keep-nut insert from Specialinsert can be used for undermount sinks, wall panels, facades, and furniture. Application involves drilling a shallow cylindrical hole and inserting the anchors using a rubber mallet. This anchoring system is especially suited for automated shops where all the holes can be plotted on CNC equipment. Once the holes are drilled, the fastener is installed in seconds…saving your crew time and saving your bottom line from additional labor costs.

A Few Key Advantages of the Keep-Nut from Specialinsert

• It’s an invisible system. The Keep-nut “self-anchoring” system is a completely internal system of fixing which eliminates any problem of packaging.
• Incredible strength (up to 562 lbs. per fastener!)
• No special equipment is necessary with the Keep-Nut – a standard drill will work perfectly fine for installation. And you won’t even need special bits – the Keep-Nut is inserted in a cylindrical hole.
• 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 easy installation
