Marketing Summary

PART #: NA2168

  • Clinchnut
  • Self-Locking

Part Number Example Callout

NA2168 SM – 02 – 1 :

NA2168 = Basic Part Number
S = Corrosion Resistant Steel (See Variations Section)
M = Solid Film Lubricant (See Variations Section)
-02 = .1900-32 Thread (See Table I in Engineering Specs)
-1 = Shank Length (See Table I in Engineering Specs)

Notes:

  1. See page 2.2 (in Engineering Specs) for installation procedure and recommended tooling.
  2. Under no circumstances will silver plating and solid film lubricant both be applied to A286 corrosion resistant steel.
  3. “M” finish code is equivalent to and supersedes “DF” finish code.
  4. For other finishes and materials contact NAFCO USA, LLC.

INSTALLATION PROCEDURE :

  1. Installation procedure is as follows:
    1. a.) Prepare hole per table II (see Engineering Specs).
    2. b.) Select proper length nut as shown in table II (refer to “T” dimension).
    3. c.) Press nut in until it is bottomed on flange.
    4. d.) Flare skirt with recommended punch and flush flaring tool, applying force sufficient for complete flaring.
  2. DO NOT chamfer or deburr hole on side from which nut is inserted.
