Product Name
Keep-Nut Sink Clips Accessory
Brief Description
The Keep-Nut Sink Clips Accessory is a comprehensive kit designed for the secure and efficient installation of undermount sinks. It comprises durable sink clips, threaded posts, wing nuts, and washers, intended for use with Keep-Nut press-in self-anchoring threaded inserts. This system provides a robust, adhesive-free fastening solution for various hard and compact materials, ensuring a reliable and professional sink installation.
Popular Applications & Uses
- Undermount sink installation in kitchen and bathroom countertops made of granite, marble, quartz, solid surface, and other compact materials.- Mounting fixtures and panels to solid surfaces.- Installation of ventilated facades and wall cladding.- Furniture assembly and shopfitting applications.- General fastening in compact materials where a strong, hidden, and permanent threaded seat is required.
Industries that Commonly Use It
- Countertop- Cabinet & Woodworking- Construction/ Building Services- Furniture- General Manufacturing- Metal Fabrication- Distributers & Resellers- Prosumer- Cladding- Plastic Fabrication- Pool/Spa/Plumbing
Special and Unique Features
- **Press-in Self-Anchoring Design:** Eliminates the need for messy resins, adhesives, or epoxies, simplifying installation and reducing cure times.- **Quick and Easy Installation:** Requires only simple cylindrical hole preparation, with no undercut drilling necessary, allowing for standard tools and fast assembly by pressure.- **High Pull-Out Strength:** Provides exceptional load-bearing capacity, with some inserts offering an average pull-out resistance of up to 562 lbs.- **Hidden and Flush-Mounted:** Creates a permanent threaded seat without any protruding parts, facilitating handling and achieving a clean, professional finish.- **Vibration Resistance:** The elastic crowns engage radially against the hole wall under tensile load, effectively locking the insert in place and providing vibration resistance.- **Prevents Bolt Extraction:** The internal thread stops before the end of the insert, preventing extraction if an excessively long bolt is used.- **Corrosion-Resistant:** Manufactured from stainless steel for durability and long-term performance, even in demanding environments.
Key Properties
- **Material:** Keep-Nut inserts are typically made of stainless steel; sink clips are often steel.- **Installation Method:** Press-in mechanical anchoring, requiring a drilled cylindrical hole and a setting tool or hammer.- **Thread Sizes:** Available in various standard thread sizes, such as 1/4-20, 10-24, 10-32, 4mm, and 6mm.- **Pull-out Strength:** High, with specific models like the IM2S/P1.4-20/H6 offering an average pull-out load of 562 lbs in porcelain.- **Components:** Consists of a threaded bush, a set of elastic crowns, and a plastic ring (for the Keep-Nut insert); the accessory kit includes male Allen posts, Z-clips, wing nuts, and washers.
Surface Compatibility
- Granite- Marble- Quartz- Solid Surface materials (e.g., Corian)- HPL (High-Pressure Laminate)- Glass- Fiber Cement- Composites (e.g., carbon, engineered stone)- Porcelain- UHPC (Ultra-High Performance Concrete)
Known backups / known substitutes
- Traditional sink clips that require drilling pilot holes and securing with screws, often used with epoxy or adhesives.- Epoxy-in anchors or inserts that rely on chemical bonding for securement.- Glue-on bonding fasteners.- Wooden support frames or blocking built into cabinets for sink support.- Standard threaded inserts (e.g., T-nuts) which may not be suitable for thin, hard, or brittle materials without specialized preparation.
Comparison Note
The Keep-Nut system, including its sink clips accessory, offers a significant advantage over traditional sink mounting methods by providing a faster, cleaner, and more mechanically robust installation. Unlike solutions requiring adhesives or resins, Keep-Nut eliminates cure times and potential mess, while its press-in, self-anchoring design ensures superior pull-out strength and vibration resistance, particularly in hard and compact materials where other fasteners may be prone to failure or difficult to install. It delivers a hidden, flush-mounted, and professional finish without the need for complex undercut drilling.
