A small diameter bolt is defined by its small diameter head, distinguishing it from a screw.
The shape of the head varies, and strictly speaking, there is no clear classification for a small diameter bolt. Small diameter is generally considered to be less than 2 mm. However, since it is limited to watch screws, the diameter is taken in a flexible manner, and a small diameter bolt is considered having only a small bolt head.
Many other types of small diameter bolts are manufactured, including hexagon socket head, Phillips head, and split head screws.
Small diameter bolts are produced to meet the requirement of an inconspicuous bolt head. Ideally, they should be recessed so that they are hidden from the exterior surfaces of the equipment.
They are used in the electrical and electronics industries, as well as in aesthetically pleasing high-end jewelry and mobile devices, such as eyeglasses and smart phones.
Assuming that small diameter bolts encompass small head screws and low-head screws, M6 screws typically have a 6 mm high head, low head bolts have a 4 mm head, and ultra-low head bolts have a head as low as 1.5 mm.
Small diameter bolts have various innovations to take advantage of their characteristics. For example, we can make thread grooves that cannot be removed with ordinary tools to prevent tampering, change the plating treatment, and make them flanged.
Small diameter bolts, capable of fulfilling the function of a bolt in limited space, are one form of bolt that reflects the miniaturization of devices such as smartphones.
Along with the miniaturization of devices, measures are also being taken to prevent loosening, which is an inherent problem with screws.
