ISO socket head machine screw sizes vary depending on the specific ISO standard. For example, ISO 4762 socket head cap screws have standard diameters ranging from M1.4 to M42, while ISO 14581 machine screws have metric diameters ranging from M1.6 to M90. Socket head cap screws are typically made from steel or stainless steel, providing corrosion resistance and tensile strength for load handling. They are used in a variety of applications, including construction, power plant parts, transmission tools, and furniture. Socket button head screws, such as those conforming to ISO 7380, feature a hexagonal recess and are driven using a standard hex wrench or insert bit. They offer higher resistance to cam-out and can be used with power drivers for faster installation.

What You'll Learn
ISO 4762 hexagon socket head cap screws
The dimensions of ISO 4762 hexagon socket head cap screws are specified by the diameter and length of the screw. The diameter, denoted by "d", represents the nominal diameter of the thread, while the length, denoted by "L", indicates the length of the bolt. Other important dimensions include the head height ("k"), groove depth ("t"), head diameter ("dk"), and the size of the internal hexagon ("s").
These screws are commonly made from steel with strength classes of 8.8, 10.9, or 12.9. Stainless steel screws are also available and are typically graded as A2, A3, or A4, with an additional digit indicating the level of corrosion resistance. For example, A2-70 represents a higher level of corrosion resistance compared to A2-50.
When selecting an ISO 4762 hexagon socket head cap screw, it is important to consider the appropriate strength class and material grade for your specific application. The surface treatment options, such as zinc plating or passivation, can also vary depending on the manufacturer and customer requirements.
