M12 Screws.

M12 Screws

What are M12 Screws?

M12 screws are a fundamental component in precision engineering, recognized by their 12mm thread size, which is crucial for achieving robust and reliable assemblies. These screws are designed to interact seamlessly with matching M12 threaded components, ensuring a secure fit that withstands mechanical loads and vibrations. With a variety of M12 screw sizes and types available, Accu's range is sure to offer something integral to your project assembly.

How M12 Screws Work.

M12 screws are pivotal in a multitude of engineering and assembly scenarios. They are commonly employed in industries such as automotive, aerospace and fabrication, where their ability to withstand high tensile forces is crucial.

The effectiveness of an M12 screw in any assembly comes from its capacity to distribute load evenly across the threads, which minimises wear and increases durability. For instance, in automotive applications, M12 screws might be used to secure engine components where high vibration and thermal stresses are common, ensuring a secure fit over the lifespan of the vehicle.

What Material M12 Screws Are Made From.

The choice of material for M12 screws significantly influences their performance characteristics. Accu's range is available in stainless steel, high tensile steel, brass, aluminium, and even advanced materials like PEEK, titanium and more, each offering unique benefits.

Stainless steel screws provide excellent corrosion resistance, making them ideal for outdoor or marine applications. Titanium screws, on the other hand, offer high strength with reduced weight, perfect for aerospace applications where every gram counts. Additionally, innovative materials like nylon and polyurethane are used for specialised applications where non-conductive or non-marring fasteners are required.

M12 Screw Sizes & Types Available.

M12 screws come in a wide range of sizes and types, from a compact 8mm in length for small tasks to a substantial 600mm for lengthy workpieces. This versatility ensures that there is an M12 fastener for almost any engineering need.

We offer a variety of M12 screw head sizes and types such as cap, pan, countersunk, grub, shoulder, captive and flanged providing options for different fixtures and load distribution requirements.

Our range of components also come with various finishes like AccuLock thread locking patches to increase resistance against vibrations and loosening along with AccuBlack chemical blackening, which enhances aesthetic appeal by achieving a matte stealth black look.

Special finishes can be customised to meet your specific project needs, emphasizing Accu's commitment to precision and quality, simply speak with our engineers.

Through the integration of precise dimensions, versatile materials, and specialized finishes, M12 screws from Accu stand as a cornerstone in precision assembly, promising performance and reliability. Whether you're selecting an M12 coach screw for robust outdoor structures or assessing the ideal m12 screw length for your latest engineering project, Accu provides the precision you need with the innovation you desire.


Q: What is M12 Size?.

A: The M12 size in screws refers to the metric designation for screws with a diameter of 12 millimetres. This measurement pertains to the external thread diameter, which is the outermost part of the screw's threads.
