HARDWARE FASTENERS Cup Head Nuts and Bolts
Cup head nuts and bolts are specialized fasteners designed for various applications, particularly in woodworking and construction. Featuring a domed head and a square neck, these fasteners, often referred to as carriage bolts, are ideal for situations where a smooth head is preferred or where the head cannot be easily accessed for tightening. The square neck prevents the bolt from turning when the nut is tightened, ensuring a secure fit. These fasteners are commonly used in timber applications, making them perfect for decks, furniture, and other structures requiring strong and reliable connections.
Available in a range of sizes and materials, cup head nuts and bolts come in both metric (diameter M6 to M24 and lengths from 18mm to 600mm) and imperial measurements (diameter 1/4" to 1/2" and lengths from 3/4" to 18"). They are manufactured from high-strength materials with finishes such as plain, zinc-plated, or hot-dip galvanized for enhanced corrosion resistance. This variety allows builders and contractors to select the right fastener based on specific project requirements and environmental conditions.
The versatility of cup head nuts and bolts makes them suitable for a wide array of construction projects. Their design facilitates easy installation, while their robust construction ensures long-lasting performance under various loads. Whether you are constructing outdoor furniture or building a sturdy deck, cup head nuts and bolts provide the strength and reliability needed for successful assembly. With compliance to relevant standards such as AS 1390 and AS 2451, these fasteners ensure safety and durability in every application.
