M3.5 Screws

What are M3.5 Screws?

M3.5 screws, a core component in precision engineering, are distinguished by their 3.5mm thread diameter, catering to applications requiring a fine balance between strength and size. These screws interact seamlessly with compatible M3.5 threads in various assemblies, ensuring a tight and secure fit. Their versatility is enhanced by Accu's array of head types available, such as countersunk and pan head, which allow them to be used in a multitude of settings where surface flush mounting or aesthetic considerations are important.

How M3.5 Screws Work.

M3.5 screws are pivotal in both everyday and specialised applications. Designed to hold components together with precision and reliability, they're crucial in industries such as electrical installation, where they are often used as m3.5 electrical screws to secure light switches and plug socket panels.

Another common usage is as m3.5 machine screws, integral in mechanical assemblies where an exact fit and strong hold are necessary. Their installation is straightforward yet precise, achieving a secure fit, a feature particularly valued in the automotive and aerospace sectors.

What Material M3.5 Screws Are Made From.

The materials on offer for Accu's range of M3.5 screws include Brass, A2 & A4 Stainless Steel, and 4140 Steel, each offering distinct advantages.

Brass screws are renowned for their aesthetics and electrical conductivity, making them ideal for electrical applications. Stainless Steel variants, known for their resilience and corrosion resistance, are suited for both indoor and outdoor environments. For applications demanding supreme strength and durability, 4140 Steel is the preferred choice. Additionally, Polyamide screws are available for lightweight needs and electrical insulation.

Size & Type M3.5 Screws Available.

Our M3.5 screws come in lengths ranging from a minimal 3mm to a substantial 100mm, accommodating a broad spectrum of engineering project requirements. Additionally, the drive types on offer include hex socket, slotted, hexagonal, thumb screw, Pozi and even m3.5 security screws, allowing you a breadth of choice when it comes to the tools used for installation.

Available head types, like the Cap Head for a high degree of driving force, countersunk for a flush fit and Grub screw for set screw applications along with many others cater to specific design needs.

Our special finishes such as AccuLock thread locking patches and AccuBlack chemical blackening not only enhance resistance against vibrations but also improve the aesthetic appeal, aligning with various industrial aesthetics and application-specific requirements.
