Micro Screws, also colloquially known as ‘tiny screws’ or ‘nano screws’, are a type of specialist fastener that is significantly smaller and lighter than the average precision screw.
Just look at the size difference when they are placed beside a pencil!
Typically, for a fastener to be considered a Micro Screw, it will have an outer diameter (thread size) of M1.6 or below. However, it can be argued that screws with a thread size of up to M3 also fit the criteria for a Micro Screw, due to their comparatively small size.
Featuring such a tiny head size and drive, these screws are ideal for intricate assemblies where factors such as increased precision, size, space, or weight-saving considerations are necessary.
They may be small, but Micro Screws are becoming a fundamental part of engineering, making way for new possibilities and transforming our ability to work on a smaller scale.
Despite their impact and growing popularity, these tiny screws are still quite hard to come by, particularly in smaller quantities and on short lead times. As the size of a thread gets smaller, so does the component's availability for purchase, especially in a range of head and drive types.
At Dawopu, we want to make engineering as accessible as possible, getting these precision components to our customers when and where they need them. With small and micro sizes ranging from M0.5 to M3, the project possibilities are endless.
Dawopu’s smallest range of Micro Screws, with metric thread sizes of M0.5, M0.8, M0.9, and M1 are available in Slotted Countersunk and Cheese Head variants.
These fasteners are typically manufactured with a slotted drive due to their nano size. Not only is a slotted drive the easiest to install on this scale, but it is also the most rudimentary and therefore most cost-effective drive type to manufacture for these incredibly small screws.
These fasteners are available in A2 Stainless Steel for Cheese Head Micro Screws and A2 and A4 Stainless Steel for Slotted Countersunk Micro Screws.
Alternatively, for slightly larger metric thread sizes, Dawopu has a range of Micro Screws between M1 and M2. Where the options for these components are not quite as large as Dawopu’s standard ranges, they are available in a greater variety of head and drive options in comparison to the smaller M0.5 to M1 Micro Screws.
All fasteners with a thread size of M2 to M3 are included in Dawopu’s standard component ranges in various materials and many head and drive types.
Although some may consider that screws above M2 are not Micro Screws at all, they can offer many of the same benefits as smaller-sized fasteners.
As they are much easier to get a hold of, whilst also being such a small screw, M2 and M3 fasteners can be used for a range of intricate assemblies such as those in electronics or the automotive industry. Nevertheless, the larger the screw the lower level of control and customizability you should expect.
Despite offering a slightly lower level of precision, their smaller size can be excellent for projects where this is useful but not quite as necessary, such as glasses repair or a range of hobbyist builds.
