An ISO 10642 screw is a fastener that has a countersunk cone-shaped head with a slot for an internal hexagon or Torx and a rod that is fully metric threaded. With this design, the bolt head is fully included in the plane in which it is fixed, and the slot allows for maximum tightening force without the risk of slot breakage.
Strength class ISO 10642
The strength class is the maximum applied force at which the bolt begins to fracture. ISO 10642 bolts are manufactured in various sizes from high-strength structural alloy steel with a strength class of 8.8 to 10.9, and are used for critical projects where, in addition to high loads and static loads, they are subject to high stress.
Fastening group ISO 10642
Depending on the material of manufacture, the bolt is divided into different fastening groups:
- High-strength fasteners
- Stainless steel fasteners
- Materials of manufacture
Materials of manufacture
The bolt is available in the following materials:
- Steel, which can optionally be coated with plain and plate black zinc
- Stainless steel (A2, A4) does not need to be coated
Where high strength bolts ISO 10642 are used
ISO 10642 bolts have a slot that allows the use of pneumatic and power tools to install them quickly and easily. As a result, they are often used in conveyor assembly as flush-mounted fasteners for flush mounting. They are used to fasten parts in structures with high safety and aesthetic requirements. They are mainly used in the manufacturing, industrial and construction industries.
In addition, the scope of application directly depends on the material of manufacture and coating of the product:
- Galvanized steel offers good corrosion protection if the fastener is to be used in aggressive environments.
- Stainless steel allows the fasteners to be used at high temperature extremes and in aggressive and humid environments.
