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 manufacture´s option. Contact Fairchild Engineering. 4. These parts are similar to FCBF2112 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 <5> An "L" in place of the dash (-) between the diameter dash number and the grip dash number designates modified break-off +.053/-.050. "EX: FCBF3005( )-6L200". <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 size. Insertion force shall not exceed 5.0 lbs. |
