Product Name
Keep-Nut Press-In Self-Anchoring Inserts (invisible hidden anchors)
Brief Description
Keep-Nut is a revolutionary press-in, self-anchoring threaded insert designed to create strong, permanent, and invisible threaded seats in a wide range of hard, brittle, and composite materials. It offers a fast, glue-free installation process without the need for adhesives or undercut holes.
Popular Applications & Uses
- Undermount sink installation- Ventilated facades and building cladding- Wall-coverings and interior design elements- Furniture assembly and fastening- Fastening of sanitary elements and kitchen components- Countertop support and installation- Panel mounting- Decorative applications and wall art
Industries that Commonly Use It
- Cabinet & Woodworking- Cladding- Concrete- Construction/ Building Services- Countertop- Fabrication- Furniture- General Manufacturing- Plastic Fabrication- Sign & Display
Special and Unique Features
- Press-in installation: Quick and easy assembly by pressure, no special tools or undercut holes required.- Self-anchoring mechanical system: Utilizes elastic crowns or toothed spring washers for strong mechanical anchoring within the material.- No adhesives or resins needed: Eliminates curing time and mess, providing a clean installation.- Invisible/hidden anchor: Installs flush for a professional, concealed finish.- High tensile and shear strength: Certified to ASTM and ETA standards, offering exceptional holding power.- Stainless steel construction: Ensures corrosion resistance and durability.- Thread stop feature: Internal thread does not run completely through the bush, preventing extraction from excessively long screws.- Versatile across materials: Compatible with a wide range of hard and composite surfaces.
Key Properties
- Material: Stainless steel (threaded bush, elastic crowns/toothed spring washers)- Installation Method: Press-in, mechanical anchoring- Thread Types: Available in Metric (M4, M5, M6) and Imperial (10-24, 1/4-20, 10-32)- Holding Power: High tensile and shear strength, pull-out resistance up to 650 lbs (per anchor) and pull-out forces up to 500 kg (per Keep-Nut)- Hole Preparation: Simple cylindrical hole, no undercut required- Certifications: European Technical Assessment ETA-15/0615, ASTM C1354 testing
Surface Compatibility
- Marble- Granite- Quartz- Natural stones- Composites- Carbon- Corian® (Solid Surface)- HPL (High-Pressure Laminate)- Glass (tempered glass)- Sintered Stone (Dekton®, Neolith®, Lapitec®)- Porcelain (Crossville®, SapienStone®)- UHPC (Ultra-High Performance Concrete)- Fiber cement- Other solid surface materials and compact materials
Known backups / known substitutes
- Adhesives/Resins: Traditional methods often involve structural adhesives or resins for anchoring in hard materials.- Undercut anchors: Other mechanical anchoring systems might require undercut holes for installation.- Lock nuts with Loctite or silicone: For general fastening where vibration is a concern, but not for creating hidden threads in solid materials.- Other threaded inserts: Various types of threaded inserts exist for different materials (e.g., wood inserts, plastic inserts), but Keep-Nut is specialized for hard, brittle, and composite panels.- Countertop brackets: For supporting countertops, some brackets are concealed but are not threaded inserts.
Comparison Note
Keep-Nut stands out from traditional fastening methods by offering a fast, clean, and strong mechanical anchoring solution without the need for messy adhesives, long curing times, or specialized undercut drilling. Its press-in installation and flush design provide an invisible and professional finish, making it particularly advantageous for aesthetic applications in stone, solid surfaces, and composites where other fasteners might be visible or require more complex preparation.
