What are M5 Screws?

M5 screws, a fundamental component in precision engineering, are characterized by their M5 thread size, equating to a 5mm diameter. These screws interact seamlessly with corresponding M5 threaded components or tapped holes, ensuring a secure and reliable connection. M5 screws are integral in applications requiring precise alignment and robust fastening, due to their well-defined M5 thread pitch and high-quality threading.

How M5 Screws Work.

M5 screws are versatile and invaluable in numerous industries, from assembly to aerospace. In machine assembly, for instance, M5 machine screws are crucial for distributing the load evenly, preventing material damage and ensuring the longevity of the assembly.

In the aerospace industry, M5 countersunk screws provide a sleek, flush finish for the fuselage, combining aesthetics with functionality. When installed, these screws improve aerodynamics while still ensuring safety and durability.

Materials of M5 Screws.

Available in a variety of materials, each M5 machine screw offers unique benefits. Brass is preferred for its corrosion resistance in humid environments, while high-tensile steel is ideal for high-strength requirements. A2 & A4 Stainless Steel screws are widely chosen for their balance of strength and corrosion resistance, making them suitable for outdoor or marine applications. For electrical insulation and lightweight needs, Nylon, PEEK, and Polycarbonate screws are the go-to options.

M5 Screw Sizes and Type.

In terms of sizes, our M5 screws range from a compact 5mm to a substantial 140mm in length, catering to your diverse project needs.

As for head types, we offer variants such as M5 cap head screws which are our go-to type for various projects. Additionally, we offer M5 grub screws for when you need to secure gearing and M5 thumb screws for when repeated access to a cover panel for example is needed.

Popular drive types like Hex, Torx and Phillips to name just a few cater to different installation tools and preferences. We cover all drive types potentially critical to your application however if you need something custom made we offer custom manufacturing of all our screws.

Lastly, special finishes like AccuLock thread locking patches enhance security with pre-applied thread lock, while AccuBlack chemical blackening offers a matte black aesthetic edge vital for seamlessly blending into black workpieces.

FAQs.

Q: What size screw is M5?.

A: M5 refers to a screw with a 5mm major thread diameter. This is measured across the crest of the threads. To see the M5 thread pitch, clearance holes and other M5 screw dimensions take a look at our metric bolt size chart.

Q: Is an M5 screw the same as #10?.

A: No, an M5 screw is not the same as a #10 screw. The M5 designation refers to a metric-sized screw with a thread diameter of 5mm. In contrast, a #10 screw is based on the imperial measurement system with a diameter of 4.83mm. The thread pitch and profile of M5 and #10 screws are also different due to the distinct measurement systems.

Q: What’s bigger, an M5 or M6 screw?.

A: An M6 screw is larger than an M5 screw, with a 6mm thread diameter compared to the 5mm of an M5 screw.

Q: Will an M5 bolt fit a 5mm hole?.

A: Theoretically, yes, an M5 bolt is designed to fit snugly through a 5mm hole. That said to account for tolerances and provide a smaller margin for error we recommend a clearance hole of 5.8mm

Q: Is M5 screw metric?.

A: Yes, the M5 screw is a metric-sized screw with a 5mm thread diameter. The M5 naming convention relates to the major thread diameter of metric screws.
