Brass Screws

What are brass screws?

Brass is an alloy of copper and zinc, providing anti-rust, non-magnetic, and corrosion-resistant properties, making these screws suitable for both indoor and outdoor environments, including some coastal settings.

Brass screws and bolts are widely used across manufacturing, construction, electrical, furniture, and decorative applications, where both performance and appearance are important.

Thanks to their conductivity and non-magnetic properties, brass screws are often specified as electrical screws in applications such as terminals, connectors, and electronic assemblies.

We supply brass screws in commonly used grade types, including:

• Brass Cu2 (CuZn37 / CZ108) – Good strength, corrosion resistance, and excellent cold workability
• Brass Cu3 (CuZn39Pb3 / CZ122) – Enhanced machinability with increased strength and corrosion resistance

Why choose brass screws?

Brass delivers a pale tan or gold-like finish, making these screws an attractive choice for visible fixings such as doors, mirrors, joinery, and architectural or period-style hardware. It is also highly machinable, though being a softer material, brass screws should be installed into a pre-drilled or tapped hole to prevent bending or stripping under high torque loads.

What types and sizes are available?

A broad selection of brass screws is available, including:

• Brass socket screws – including socket cap, countersunk, and set screws, designed for use with hex keys for secure tightening and a clean, low-profile finish.
• Brass machine screws – suitable for precision fastening in mechanical and electrical applications
• Brass thumb screws – designed for hand tightening and easy adjustment
• Brass slotted screws – commonly used in traditional, decorative, and light-duty applications

Brass socket screws are particularly popular in engineering and electrical applications, where their internal hex drive allows higher torque transfer and a more compact head design.

Sizes are supplied mainly in metric threads, with some imperial sizes available on request.

Thread locking patches can be optionally applied to improve resistance to vibration and self-loosening.

We can also supply bespoke brass screws, manufactured to drawing in non-standard sizes, specialist grades and custom finishes. Minimum order quantities apply.
