Specification
| Item | Value |
|---|---|
| Type | Blind bolt, internally threaded |
| Material | Nut 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). |
| Strength | Per table: prevailing torque, double-shear and tensile strength minimums by diameter |
| Locking | Self-locking: three indents 120° apart on the nut, about .040 above where the nut nose angle meets the outside diameter (mean grip) |
| Item | Value |
|---|---|
| Finish | Nut 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. |
| Procurement | ESCBB-2 Class I |
| Status | Manufacturer drawing, revision shown in the source block. Check the manufacturer for any later revision before ordering. |

Part number
What each code means
| Part | Meaning |
|---|---|
| Format | PLT210-<dash> |
| Example | PLT210-05-05 — Diameter code -05 (nominal body diameter .1635 in), 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.
- Protruding hex head with an optional indent. Break-off limits are measured from the skin surface and are given as two signed values.
- For PLT210-05-01 and PLT210-06-01 the prevailing torque is recorded over only 360° of nut rotation.
