Notes

N/A 2. Locking feature consists of three (3) indentations located 120° apart on the periphery of the nut component.
<3> Alternate head marking: "VS" and "O".
4. Composite blind fasteners with selected combinations of the above lubrications and finishes are specially coded and may be substituted for equivalent non-coded parts at manufacturer´s option. Contact Fairchild Engineering.
<5> 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. "EX: FCBF2210( )-6LL200."
<6> Distortion shall not prevent insertion of the fastener into a ring gauge of length equal to one diameter and hole diameter equal to minimum recommended hole. Insertion force shall not exceed 5.0 lbs.
<7> These parts are similar to FCBF2110 except as follows:
A.) Improve out-of-grip flagging capability (corebolt B/O).
B.) Increased blind side protrusion before and after upset.
C.) Increased installed weight.
