Specification

ItemValue
TypeBlind bolt, internally threaded
MaterialNut and screw: alloy steel (4130 per AMS-S-6758, 4140 per AMS 6382 or AMS 6349, or 8740 per AMS 6322), heat treated per AMS 2759 to roughly 180,000-200,000 psi tensile (HRC 39-43). Sleeve: corrosion-resistant steel 303 or 304 (AMS-QQ-S-763, AMS 5639 or AMS 5641).
StrengthPer table: prevailing torque, double-shear and tensile strength minimums by diameter
LockingSelf-locking: three indents 120° apart on the nut, about .040 above where the nut nose angle meets the outside diameter (mean grip)
ItemValue
FinishNut and screw: cadmium plate per AMS-QQ-P-416 Type II Class 2 (NAS672 cadmium is acceptable if followed by a dichromate treatment). Sleeve: passivated per AMS 2700, or cadmium plate per AMS-QQ-P-416 Type I Class 3.
ProcurementESCBB-2 Class I
StatusManufacturer drawing, revision shown in the source block. Check the manufacturer for any later revision before ordering.

Part number

What each code means

PartMeaning
FormatPLT111-<dash>
ExamplePLT111-05-05 — Diameter code -05 (nominal body diameter .179 in, oversize), grip dash -05 (nominal grip 5/16 in; usable range .282-.344 in)

Notes from the standard

  • Part number format: basic number, diameter dash (-05 to -12) and grip dash in sixteenths of an inch, for example -05 = a nominal grip of 5/16 in (usable range .282-.344 in; the table column G is the nominal grip plus .031).
  • Half grips are ordered by adding .5 to the grip dash (e.g. -06-4.5 = 4.5 sixteenths = .281 in nominal); their grip range is nominal +.031 / -.030 in, and the -1.5 grip is limited to .078-.125 in.
  • Grips shorter or longer than the tabulated ones may exist as specials; on shorter grips the break-off limits and prevailing torque in the table do not apply.
  • Tolerance on G: +.030/-.010 for -05 and -06; +.040/-.010 for -08 and -10; +.050/-.010 for -12.
  • Head marking: N = Monogram, VS = Voi-Shan; 'SL' marks self-locking; a square symbol marks alloy steel. Marking on the nut head is depressed .010 max.
  • Dimensions are before lubrication. Standard finishes and lubes are on the drawing; special finishes are covered by the manufacturer's separate specification ESCBB-4.
  • An insertion-gauge check applies to the locking area: a ring gauge with the bore at D max + .001 must accept the fastener with a push of no more than 5 lb.
  • 1/64 in oversize version of the PLT110 head: a dash printed in the head marking identifies the oversize D diameter.
  • Break-off limits are measured from the head of the nut. A, A' and H are theoretical reference values and are not used for inspection.
