<6>Alternate head marking: ("VS") and "2013".
7.Composite blind fasteners with selected combinations of the above lubrications and finishes are specially coded amd may be substituted for equivalent non-coded parts at manufactures option. Contact Howmet Fastening Engineering Systems.
<8>An "L" in place of the dash (-) between the diameter dash number and the grip dash number designates modified break-off limits of +.053/-.050.
<9>An "LL" in place of the dash (-) between the diameter dash number and the grip dash number designates midified break-off limits of +.003/-.100.
<10>Distortion shall not prevent insertion of the fastener into a ring gauge of length equal to one diameter and hole diameter equal to a minimum recommended hole. Insertion force shall not exceed 5.0 lbs.
