This part of ISO 898 specifies mechanical and physical properties of set screws and similar threaded fasteners made of carbon steel or alloy steel when tested at an ambient temperature range of 10 °C to 35 °C.

Fasteners
- the term used when set screws and similar threaded fasteners are considered all together
- that conform to the requirements of this part of ISO 898 are evaluated at that ambient temperature range.
Fasteners according to this part of ISO 898 are classified to specified hardness classes and are intended for use under compressive stress only.
NOTE Fasteners conforming to the requirements of this part of ISO 898 are used in applications ranging from - 50 °C to +150 °C. Users are advised to consult an experienced fastener metallurgist for temperatures outside the range of - 50 °C to +150 °C and up to a maximum temperature of +300 °C when determining appropriate choices for a given application.

This part of ISO 898 applies to set screws and similar fasteners
a) made of carbon steel or alloy steel,
b) having a triangular ISO metric screw thread according to ISO 68-1,
c) with a coarse pitch thread M1,6 to M30, and fine pitch thread M8×1 to M30×2,
d) with diameter/pitch combinations according to ISO 261 and ISO 262,
e) having thread tolerances according to ISO 965-1, ISO 965-2 and ISO 965-4.

It does not specify requirements for such properties as
- tensile strength (see ISO 898-1),
- shear strength,
- weldability,
- corrosion resistance,
- ability to withstand temperatures above + 150 °C or below - 50 °C.
