This part of ISO 898 specifies mechanical and physical properties of bolts, screws and studs made of carbon steel and alloy steel when tested at an ambient temperature range of 10 \u00b0C to 35 \u00b0C. Fasteners (the term used when bolts, screws and studs are considered all together) that conform to the requirements of this part of ISO 898 are evaluated at that ambient temperature range. They might not retain the specified mechanical and physical properties at elevated temperatures (see Annex B) and\/or lower temperatures.<\/p>\n
\nNOTE 1 Fasteners conforming to the requirements of this part of ISO 898 are used in applications ranging from \u221250 \u00b0C to +150 \u00b0C. Users are advised to consult an experienced fastener metallurgist for temperatures outside the range of \u221250 \u00b0C to +150 \u00b0C and up to a maximum temperature of +300 \u00b0C when determining appropriate choices for a given application.<\/p>\n<\/blockquote>\n
\nNOTE 2 Information for the selection and application of steels for use at lower and elevated temperatures is given, for example, in EN 10269, ASTM F2281 and in ASTM A320\/A320M.<\/p>\n<\/blockquote>\n
Certain bolts and screws might not fulfil the tensile or torsional requirements of this part of ISO 898 because the geometry of their heads reduces the shear area in the head compared to the stress area in the thread. These include bolts and screws having a low or countersunk head (see 8.2).<\/p>\n
This part of ISO 898 is applicable to bolts, screws and studs<\/p>\n
