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.
3.Composite blind fastener 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.
<4> 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. Force for insertion shall not exceed 5.0 lbs.
<5> An "L" in place of the dash (-) between the diameter dash number and grip dash number designates modified break-off limits of +.053/-.050. "EX: FCBF3014( )-6L200".
