MATERIAL:
  • Nut: Aluminum alloy.
  • Housing : Alloy steel.
FINISH:
  • Nut: Anodized, blue color. Cetyl alcohol.
  • Housing : Cadmium plate.
LOCKING INSERT: Gold color nylon (250° F max. performance).

PERFORMANCE: NASM 25027 applicable.

THREADS: In accordance with AS-8879 before lubrification.

FLOATABILITY: Float of the nut portion of assembly shall not be less than .030 laterally and longitudinally from the centered position. Nut body shall be capable of engagement with a bolt in the maximum misaligned position. Maximum vertical float within the housing .020 for .1900 size and smaller .030 for .2500 size and larger.

VARIATION: Add « K » for bottom c’sunk rivet holes, for example: SNLA-039-3K.

APPLICATION: Type SNLA parts are designed for use with oversize clearance holes to permit interchangeable mounting of parts and sub-assemblies with a lesser degree of alignment accuracy than is usually required with fixed nuts.

NOTES: For oversize rivet holes, (.161 DIA. for sizes -7 and -8 per NAS 1031) add code Q after the reference (ex: SNLA 039-7Q) .This variation is subject to a minimum order quantity if not available from stock. The P/N SNLA 039-7 and SNLA 039-8 do not conform to NAS 1031.
