Product Name
Keep-Nut Allen-Style Rods Posts (used with Keep-Nut Self-Anchoring Threaded Inserts)
Brief Description
Keep-Nut Allen-Style Rods Posts are male threaded posts specifically designed to be used in conjunction with Keep-Nut self-anchoring threaded inserts. The Keep-Nut inserts themselves are revolutionary press-in fasteners that create strong, permanent female threads in a wide range of hard and composite materials without the need for adhesives or resins. These posts provide a robust and often concealed attachment point for various applications.
Popular Applications & Uses
- Securing undermount sinks to countertops made of granite, marble, quartz, and solid surface materials.- Mounting ventilated facades and wall cladding systems.- Furniture assembly and shopfitting.- Interior décor and panel attachment.- Fixing kitchen and sanitary elements.- Signage mounting and display fixtures.- General high-strength fastening in composite panels and other compact materials.
Industries that Commonly Use It
- Construction/Building Services (for facades, wall cladding, interior panels)- Furniture (for assembly, shopfitting, kitchen/bathroom elements)- Countertop (for undermount sink installation)- Cladding (for ventilated facades and wall coverings)- Metal Fabrication (for general fastening solutions)- Plastic Fabrication (for solid surface, HPL, composites)- Sign & Display (for panel and signage mounting)- Marine (for composite applications)- Aerospace/Defense (for composite applications and high-strength fastening)- General Manufacturing (for diverse fastening needs in various products)
Special and Unique Features
- Self-anchoring mechanical feature, eliminating the need for adhesives or resins during installation.- Fast and easy press-in installation into a simple cylindrical hole, without requiring an undercut hole.- Manufactured from stainless steel, providing excellent resistance to rust and corrosion.- Creates permanent, high-strength threads in hard and compact materials.- Flush-mount design ensures a professional, concealed finish.- The internal thread does not run completely through the bush, preventing extraction from excessively long screws.- Versatile for use in various panel thicknesses, including thin materials (down to 5.5 mm).
Key Properties
- Material: Keep-Nut inserts and Allen posts are typically made of Stainless Steel.- Installation Method: Press-in for the Keep-Nut insert, followed by threading in the Allen-style rod post.- Anchoring Mechanism: Mechanical anchoring achieved by a set of toothed spring washers (crowns) that engage radially against the hole wall.- Thread Types: Available in both Metric (M4, M5, M6) and Imperial (10-24, 1/4-20, 10-32) threads for compatibility with various fasteners.- Strength: Offers high tensile and shear strength, with reported values ranging from 250 to 1,000 pounds per fastener depending on the model and material.- Corrosion Resistance: Inherently corrosion-resistant due to stainless steel construction, suitable for interior and exterior applications.
Surface Compatibility
- Natural Stone: Marble, Granite, Quartz, Sintered Stone (e.g., Dekton®, Neolith®, Lapitec®).- Solid Surface Materials: Corian®, Hi-Macs®, Staron®, HPL, Wilsonart® Thinscape®.- Composites: Carbon fiber, fiberglass, GRP, and other composite panels.- Glass: Tempered glass.- Porcelain.- Fiber Cement.- UHPC (Ultra-High Performance Concrete).- Dense Plastic Panels: Including acrylics and laminates.
Known backups / known substitutes
- Other types of threaded inserts: Such as helical wire inserts, key-locking inserts, rivet nuts (blind threaded inserts), self-tapping inserts (e.g., Tappex Trisert-3, Foamsert), molded-in inserts, and other press-in inserts for various materials.- Bonding fasteners: Systems like Master-Plate or bigHead fasteners that rely on adhesive bonding or molding-in for composite materials.- Adhesive-based anchoring systems: While Keep-Nut avoids adhesives, other solutions might use them for fastening.- Traditional fastening methods: Including bolts/screws with nuts, potentially enhanced with lock nuts, thread-locking compounds (Loctite), or welding for secure connections.- Specialized brackets: Such as CounterBalance® steel brackets for countertop support.
Comparison Note
Keep-Nut inserts, and by extension the Allen-Style Rods Posts that utilize them, offer a significant advantage over many traditional fasteners and other threaded insert types. They provide a strong, permanent, and concealed threaded anchor in challenging hard and composite materials without the need for messy adhesives, resins, or complex undercut holes. The installation process is notably quick and simple, requiring only a standard cylindrical hole and a press-in action. This contrasts with adhesive-based systems that demand curing time, or other mechanical inserts that may necessitate specialized tooling, intricate hole preparation, or are not suitable for very hard or thin substrates. The Allen-style rods posts specifically leverage this robust system to create reliable, invisible mounting solutions.
