Notes

N/A 2.Locking feature consists of three (3) indentations located 120° apart on the periphery of the nut component and approximately .040" above intersection of the nut nose angle and O.D.
<4> Alternate markings: "VS" and "2011"
5.Composite blind fasteners with selected combinations of the above lubrications and finishes are specially coded and may be substituted for equivalent of non-coded parts at manufacrure´s option. Contact Fairchild Engineering.
5. An "L" in place of the dash (-) between the diameter dash number and the grip dash number designates midified break-off limits of +.053/-.050. (e.g. FCBF2211( )-6L200).
<7>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.
8. These parts are similar to FCBF2111 except as follows:
A. Improved out-of-grip flagging capacity (corebolt B/O)
B. Increased blind side protrusion before and after upset
C. Increased installed weight
