These fasteners are commonly used in wood-to-wood fastening applications where a secure and concealed connection is required. Joint connector nuts are typically installed into a pre-drilled hole in one piece of wood and paired with a compatible bolt or machine screw that passes through a second piece of material. When tightened, the bolt engages the threaded connector nut to create a strong clamping force that securely joins the two components together. Each connector nut features a hex socket drive, allowing installers to position and tighten the nut using a hex key or Allen wrench. This design helps maintain proper alignment during installation and prevents slippage while tightening. These connector nuts are manufactured from durable steel and feature a black oxide finish that provides moderate protection against corrosion while maintaining a clean, professional appearance commonly used in furniture hardware. The nuts feature a 1/4"-20 coarse thread and measure 1/2 inch in length, making them compatible with bolts and machine screws of the same thread size used in furniture assembly and cabinetry installations. Packaged in a convenient refill box containing 12 connector nuts, these fasteners are ideal for furniture builders, cabinet installers, contractors, and DIY homeowners working on furniture repair, cabinetry projects, shelving installations, and woodworking assemblies requiring reliable hidden fasteners. From the Manufacturer These nuts are used with connector bolts. They have the same head and diameter of the bolt they are used with, and give a pleasing look on both sides of the joint. Used typically in cabinetry and furniture making and offer the flexibilty of disassembling and assembling many times. ## Features - JOINT CONNECTOR NUTS FOR WOOD FURNITURE FASTENING: 1/4 in.-20 joint connector nuts are designed for internal wood-to-wood connections in furniture assembly, cabinetry, shelving, bed frames, and woodworking projects requiring strong joins. - HEX SOCKET DRIVE FOR CONTROLLED INSTALLATION: Hex socket drive allows precise tightening with a hex key or Allen wrench, preventing slippage during installation and enabling proper alignment inside the material for a secure connection. - COMPATIBLE WITH 1/4 IN.-20 COARSE THREAD BOLTS AND SCREWS: 1/4 in.-20 coarse thread pairs with compatible bolts and machine screws to create a strong, stable internal fastening system for furniture hardware and cabinetry assemblies. - STEEL WITH BLACK OXIDE FINISH FOR CORROSION RESISTANCE: High-quality steel construction provides strong holding power.
