MATERIAL: Alloy steel heat treated.

FINISH : Nut & Basket - Cadmium Plate, AMS-QQ-P-416, Type II, Class 2.

LOCKING INSERT: Gold Color Nylon - Heat Stabilized (Suitable for temperatures up to 210° F).

PERFORMANCE : Ø10/32 : NASM 25027 except : torque out 40 inch (1 complete single cycle after heating for 6 hours at 210°F).

THREADS: In accordance with AS 8879.

FLOATABILITY: Minimum radial .020 within limits of « B » dimension.

APPLICATION: Type NSF 88 Clinch Nuts are particularly suited for use in applications where limited mounting or wrenching areas make use of miniature fixed nut desirable since the spline on the nut shank must broach into the work. Installations are usually limited to use in thin Aluminum or soft Steel Sheets or plates, the floating nut component adds advantage to the use of NSF 88 since it relaxes the usual requirements for close bolt hole alignments in making assembly stack-ups.

Additional Information

N/A Shank Length Selection

Note 1:

  • Parts are recommended for use in sheet thicknesses of .050 minimum.
  • For optimum installation it is recommended that the proper tools be used, and that the maximum tabulated clinching pressures not be exceeded.
  • Exceeding these values can, depending upon the material into which the nut is installed cause distortion of the work and/or the nut itself.
  • The most satisfactory installations are obtained when the nut is pressed into the work until its shoulder rests against the surface of the work. The shank should then be flared.
  • It is recommended that the acting surface of the punch face be maintained. Both the Punch and the Dolly should be regularly inspected and cleaned of any plating « Build-up » in order to assure proper seating of the nut.
  • Thread sizes -04 and -06, are not available with the -3 (.090) shank length as of printing of this catalog consult SIMMONDS for availability.
