A spacer conforming to figure I() may be used under the head of protruding head fasteners to provide clearance for the fastener head-to-shank fillet radius. Plain flat spacers may be used under the nut. 4.1.2.2 Test nuts. T

Threaded adapters may be used on shear fasteners through one-half inch diameter or tension fasteners too short to test with nuts on available fixtures. Locking devices are not permitted. Type A or B nuts may be used for testing bolts under 260 ksi. A fatigue test nut may be reused for not more than five tests, provided the nut meets the dimensional requirements and has not been damaged by a previous test and the same nut is used for testing the same lot of bolts.
