GC20N Series Corrugated Fasteners are narrow crown corrugated fasteners designed for picture frame mitre joints, mirror frames, light furniture, cabinet assembly, drawer construction, wood boxes, upholstery bed frames and repair work on cracked or split wood. With a 15.6mm / 5/8 inch crown, 0.5mm thickness and 10mm to 13mm length range, GC20N fasteners create strong, hidden wood joints with minimal surface visibility.
The wavy corrugated design clamps adjacent wood fibers together and helps eliminate gaps in mitre joints, corner connections and spliced boards. GC20N is made from steel sheet and is available in bright, galvanized and phosphate coated finishes for different furniture, frame and woodworking applications.
GC20N corrugated fasteners are thin strips of steel with alternating grooves and a sharp chisel edge. When driven into wood, the corrugated profile grips both sides of the joint, clamps the material together and produces strong hidden holding power. This makes GC20N a practical choice for picture frame shops, furniture manufacturers, cabinet makers, wood box producers and repair workshops.
