Micro Screws: An Industrial Essential

What is a micro screw?

Micro screws, also known as precision screws, are very small but have a wide range of applications and are indispensable industrial products. Micro screws can have diameters as small as 0.3mm to 1.4mm and play a crucial role in various industries. They are widely used in medical, aerospace equipment, wearable devices, biopharmaceuticals, electronics, LED displays, eyewear, watches, precision electronics, and other fields.

Classification of micro screws

Micro screws are generally divided into two categories: self-tapping micro screws and machine-thread micro screws. The difference between these two lies in the type of threads and thread shapes, one being self-tapping and the other mechanical.

Self-tapping micro screws

Self-tapping micro screws come in various head shapes, including pan heads, countersunk heads, and half countersunk heads. The tail end shapes vary as well, with common forms being pointed and flat ends. Additionally, they can come with or without washers. Unlike traditional mechanical thread screws, self-tapping micro screws are mostly used on non-metal products and do not require pre-tapping before installation. They are mainly applied to products made of plastic shells and other materials. The thread shape design closely correlates with the material hardness and bearing capacity of plastic components, so different plastic components require different self-tapping thread shapes. Furthermore, self-tapping screws have excellent anti-loosening capabilities, providing more reliable connections.

Machine-thread micro screws

Machine-thread micro screws do not have a pointed tail end. The thread is relatively uniform, and the screws require pre-tapped threads in the matching workpiece before use. They are generally used in conjunction with nuts. When assembling products, the screws are turned into parts to play a fixing role.

Applications of micro screws

Electronic products

In devices like smartphones, laptops, and wearable devices, micro screws are used to securely fix components within very limited spaces.

Medical equipment

Custom micro screws are critical in the assembly of medical devices where non-magnetic, high strength, and biocompatibility materials are required.

Optical equipment

In cameras and other optical devices, micro screws are used for precise assembly to ensure adjustable mechanisms run smoothly without compromising the integrity of the equipment.
