Product Name
Keep-Nut Tooling Kits
Brief Description
Keep-Nut Tooling Kits provide the essential tools for the accurate and damage-free installation of Keep-Nut press-in, self-anchoring threaded inserts. These inserts are designed to create permanent, high-strength threaded seats in a wide range of solid and compact materials without the need for adhesives or resins. The kits typically include specialized drill bits, go/no-go gauges for hole verification, and setting tools for secure insertion.
Popular Applications & Uses
- Undermount sink installation in countertops (granite, marble, quartz, solid surface, porcelain).- Ventilated facades and wall cladding.- Furniture assembly and shopfitting.- Décor and interior design elements.- Kitchen and bathroom elements.- Panel mounting and composite panel fabrication.- Signage mounting.- Funerary art.
Industries that Commonly Use It
- Construction/ Building Services (for facades and cladding)- Countertop (for sink installation)- Furniture (for assembly and fixtures)- Cladding (for panel fixing)- Plastic Fabrication (for solid surface, HPL, composites, plastics)- Sign & Display (for mounting signage)- Fabrication (general material fabrication) - General Manufacturing (for various product assemblies) - Cabinet & Woodworking (for furniture, kitchen elements, laminated timber)- Concrete (for UHPC applications)- Aerospace/Defense (for composite and carbon panel applications)- Automotive Service/Repair (for composite components in specialty vehicles)- Marine (for composite applications in vessels)- Transportation/ Specialty Vehicle (for various vehicle components using compatible materials)
Special and Unique Features
- Press-in, self-anchoring mechanical system for permanent threads.- No adhesives, resins, or curing time required for installation.- Simple cylindrical hole preparation; no complex undercut holes needed.- Fast and easy installation by applying pressure.- Allows for hidden assemblies without any protruding parts, facilitating material handling.- Mechanical anchoring achieved by elastic crowns engaging radially against the hole wall under axial force.- Internal thread does not run completely through the bush, preventing extraction from excessively long screws.- High pull-out and shear strength, certified to ASTM and ETA standards.- Flush-mount design for a professional, concealed finish.- European Technical Assessment ETA-15/0615 certified for façade panels.
Key Properties
- Material: Manufactured from stainless steel.- Anchoring Mechanism: Mechanical, press-in, self-anchoring.- Installation Method: Requires drilling a cylindrical hole, followed by press-in insertion using a setting tool.- Thread Types: Available in Metric (M4, M5, M6) and Imperial (10-24, 1/4-20, 10-32).- Components: Consists of a threaded bush, a set of elastic crowns (toothed spring washers), and a plastic ring holding the parts together.- Durability: Rust-resistant due to stainless steel construction.- Strength: Offers high tensile and shear strength.
Surface Compatibility
- Natural Stones: Marble, Granite, Quartz, other natural stones.- Solid Surface Materials: Corian®, Hi-Macs®, Staron®, other solid surfaces.- Engineered Stones: Sintered Stone (Dekton®, Neolith®, Lapitec®), Porcelain (Crossville®, SapienStone®).- Composites: Carbon, fiberglass, other composite panels.- Laminates: HPL (High-Pressure Laminate), laminated timber.- Glass: Tempered glass (from 5mm thickness).- Other Compact Materials: Fiber cement, UHPC (Ultra-High Performance Concrete), acrylics, dense plastic panels, agglomerate.
Known backups / known substitutes
- Adhesives and bonding agents (e.g., epoxy for undermount sinks).- Traditional threaded inserts that require adhesives or resins for installation.- Undercut anchors (which Keep-Nut aims to simplify by not requiring an undercut hole).- Deform-Nut® (for sandwich panels, utilizing mechanical and chemical bonding).- Master-Plate® bonding fasteners (for composites, fiberglass, laminate, carbon fiber, using adhesive bonding or molding in).- General rivet nuts or blind rivet nuts.
Comparison Note
Keep-Nut Tooling Kits facilitate the installation of a revolutionary fastening system that provides a fast, glue-free, and mechanically anchored solution for creating permanent threads in hard, compact, and solid materials. Unlike many traditional methods that often rely on messy adhesives, resins, or require complex undercut holes, Keep-Nut inserts are installed quickly by simply pressing them into a pre-drilled cylindrical hole. The use of stainless steel ensures durability and rust resistance, while the flush-mount design delivers a professional, concealed finish. The unique mechanical anchoring system provides superior pull-out and shear strength, backed by industry certifications, offering a reliable and efficient alternative to conventional fastening techniques.
