Aluminum screws are high-precision fasteners designed to deliver incredible lightweightedness, strength and corrosion resistance, making them essential for applications where reducing weight is key.
These precision screws are engineered to interact perfectly with other threaded components, ensuring a secure and lasting fit. They come in different head styles, such as aluminium cap head screws and aluminium countersunk screws, making them versatile for various engineering project needs.
Their ability to pair effectively with a wide range of materials, including metals and composites, makes them a go-to choice in many advanced manufacturing environments.
When installed, aluminium screws create a strong, reliable bond that can withstand substantial mechanical stress without adding unnecessary weight to the assembly. This makes them particularly useful in industries where weight reduction is crucial, such as in the aerospace sector.
For instance, aluminium aerospace screws must meet stringent specifications to ensure the safety and efficiency of aircraft, and aluminium’s lightweight properties make it an ideal material for such high-performance applications. Whether used in securing panels on an aircraft or assembling delicate electronic components, aluminium screws deliver the precision and dependability needed.
As expected, our aluminium screws are crafted from high-grade aerospace aluminium, a material prized for its excellent strength-to-weight ratio and natural corrosion resistance. This is particularly useful in environments exposed to moisture or chemicals, where aluminium’s protective oxide layer prevents rust from forming.
The non-magnetic properties of aluminium are also critical for applications in electronics or medical devices.
For even more demanding situations, know our high-performance aerospace-grade screws made from specialised aluminium alloys offer enhanced performance where durability and reliability are non-negotiable.
At Accu, our aluminium machine screws come in a wide range of sizes and types to suit different engineering needs. You’ll find screws as short as 5mm and as long as 70mm, with thread sizes ranging from M3 to M10. This variety ensures you can find the right aerospace fastener, whether you’re working in tight spaces or need a longer fastener for more substantial assemblies.
In terms of head types, you can choose between aluminium cap head screws, which provide an even load-bearing head, and aluminium countersunk screws, which sit level with the surface for a smooth, unobtrusive look.
Both types feature a hex socket drive, making them easy to install and remove with standard tools. Additionally, these screws can be finished with clear anodising to further boost corrosion resistance and improve their appearance, making them ideal for specific applications.
For other options, you might want to explore our range of high-quality PEEK screws or titanium screws, which offer alternative solutions where weight reduction and tensile strength are factors. These options ensure that no matter what your project requires, there’s a perfect precision screw ready to meet the challenge.
A: Aluminum screws are known for their excellent strength-to-weight ratio. While they may not be as strong as steel screws, they provide sufficient strength for many applications, especially where reducing weight is a priority.
A: Yes, aluminium screws can be used with a wide range of materials, including metals, plastics and composites. They are particularly effective in applications where corrosion resistance is needed, as aluminium naturally resists rust. However, it's important to ensure that the materials you are fastening together are compatible to avoid issues like galvanic corrosion when combining different metals.
A: Our aerospace-grade aluminium screws are made from aluminium 7075 T6, a high-strength alloy known for its superior performance in extreme conditions. This material is commonly used in the aerospace industry due to its exceptional strength, durability and resistance to stress and corrosion. The use of Aluminum 7075 T6 ensures that our screws meet the rigorous standards required for aerospace applications, delivering reliability and performance you can trust.
High precision, bespoke manufacture of Aluminum Screws to customer specification. State of the art facilities specialising in both small batch prototyping and large scale manufacture.
