Bridge the gap between different materials with our BZP Wood to Metal Dowels, commonly known as hanger bolts. Widely regarded as an ingenious fastening solution within the furniture manufacturing and joinery industries, these headless studs feature a coarse wood screw thread on one end and a standard metric machine thread on the other. Finished in Bright Zinc Plating (BZP) for reliable indoor corrosion resistance, they allow you to create a robust, protruding metal stud perfectly suited for attaching table legs, architectural hardware, or suspended fixtures to a wooden substrate.

Dual-Thread Design: Features a self-tapping wood thread on one half and a standard machine thread on the other for seamless material transitions.

Invisible Fastening: Leaves no visible screw head once installed, making them the ultimate choice for clean, hidden joints in premium furniture.

Reliable Corrosion Resistance: Coated in a Bright Zinc Plating (BZP) to protect the steel core from oxidation in dry, indoor environments.

The Ingenious Dual-Thread Solution

Joining metal hardware to timber securely can be a design challenge, especially when you need to repeatedly assemble and disassemble the parts. Using a standard wood screw straight through a metal bracket looks messy and wears out the timber over time. Wood to metal dowels (hanger bolts) solve this beautifully. By driving the coarse wood-thread side permanently into your timber, you are left with a sturdy, protruding machine thread. You can then attach metal brackets, table legs, or architectural hardware using a standard nut. If the furniture ever needs to be dismantled, you simply unscrew the nut without ever wearing out the wooden anchor point.

Essential for Furniture Manufacturing

If you have ever attached a wooden leg to a new sofa or assembled a premium dining table, you have likely interacted with a hanger bolt. They are an absolute staple in the furniture and joinery industries because they allow for completely "blind" or hidden joints. Because there is no screw head, the fastener is entirely concealed inside the two materials being joined. This provides incredible structural rigidity without ruining the aesthetic lines of your woodworking projects.

Reliable BZP Protection

These hanger bolts are manufactured from high-strength steel to ensure they don't bend or snap under the shear weight of heavy furniture or suspended fixtures. To ensure long-lasting performance, they are treated with a Bright Zinc Plated (BZP) finish. This provides a sleek silver appearance and offers excellent protection against rust and oxidation, keeping your indoor joints structurally sound and easy to unfasten for years to come.

Key Features

Wood to Metal Transition: Instantly converts a standard pilot hole in timber into a highly secure machine-threaded stud.
Headless Stud Profile: Allows nuts, tapped metal components, or threaded furniture legs to be spun directly onto the protruding end.
Furniture Industry Standard: The go-to fastener for flat-pack assembly, attaching sofa feet, stair balustrades, and suspended ceiling fixtures.
Strong Anchor Point: The coarse, deep-biting wood thread provides massive pull-out resistance in both hardwoods and softwoods.
Bright Zinc Plated (BZP): Delivers a clean, professional finish while acting as a sacrificial barrier against rust.

Frequently Asked Questions

How do I drive a headless screw into the wood?

There are two common methods. You can use a dedicated "hanger bolt driver" that chucks into your drill. Alternatively, you can use the "double-nut" method: thread two standard nuts onto the machine-thread side, tighten them against each other using two spanners to lock them in place, and then use a socket on the top nut to drive the wood thread into your timber. Once installed, simply unlock and remove the nuts.

Do I need to drill a pilot hole first?

Yes, absolutely. You must drill a pilot hole into the timber for the wood-thread side. Driving a thick hanger bolt directly into wood without a pilot hole will almost certainly cause the timber to split.

Can I use these for outdoor woodworking?

The Bright Zinc Plated (BZP) finish is designed for indoor, dry environments. For outdoor projects like decking or exterior wooden structures, you should use stainless steel hanger bolts to prevent them from rusting and snapping over time.
