Keep-Nut Parts Kit, 1/4"

The Keep-Nut Parts Kit supports a press-in threaded insert system designed to provide permanent threads in panels made from marble, granite and other stone materials. Keep-Nut inserts are manufactured from stainless steel and consist of a threaded bush, toothed spring washers known as crowns and a plastic ring that holds the components together.

Installation requires only a cylindrical hole with the correct diameter. Once pressed into place, the crowns engage under axial force and act radially against the hole wall to lock the insert securely within the material.

Keep-Nut inserts are developed for fastening ventilated facades, wall coverings, décor and interiors, furniture, kitchen and sanitary elements and other applications.

Features and Benefits

• Requires only a cylindrical hole without undercutting
• Allows standard tools to be used for hole preparation
• Installs quickly by pressure without resins or adhesives
• Supports hidden assemblies without protruding components
• Crowns spread the load into the surrounding material while the insert is under tensile load
• Internal thread stops before the end of the insert to help prevent extraction caused by an excessively long screw or bolt
• Available in different lengths and with or without a flange to accommodate various panel thicknesses
