1.1 This specification covers the requirements for compressible-washer-type direct tension indicators, (DTIs) capable of indicating the achievement of a specified minimum bolt tension in a structural bolt.
1.2 Eight types of DTIs in nominal diameter sizes 1/2 through 11/2 in. as well as M16 through M36 are covered:
1.2.1 Type 325-1—DTIs for use with Specification A325 Type 1 bolts or F8201; or F1852 assemblies.
1.2.2 Type 325–3—DTIs for use with Specification A325 Type 3 bolts or F1852 Type 3 assemblies.
1.2.3 Type 490–1—DTIs for use with Specification A490 Type 1 bolts or F2280 assemblies.
1.2.4 Type 490–3—DTIs for use with Specification A490 Type 3 F2280 Type 3 assemblies.
1.2.5 Type 8.8-1—DTIs for use with Specification A325M Type 1 bolts.
1.2.6 Type 8.8-3—DTIs for use with Specification A325M Type 3 bolts.
1.2.7 Type 10.9-1—DTIs for use with Specification A490M Type 1 bolts.
1.2.8 Type 10.9-3—DTIs for use with Specification A490M Type 3 bolts.
