AIA/NAS 1003-1020-2010 pdf download BOLT, MACHINE, HEXAGON HEAD, A286 CRES
CODE: BASIC PART NUMBER DESIGNATES NOMINAL DIAMETER.
DASH NUMBER DESIGNATES GRIP AND LENGTH (SEE SHEET 3).
ADD “A” TO DASH NUMBER FOR UNDRILLED BOLT.
ADD “H” TO DASH NUMBER FOR DRILLED HEAD ONLY.
NO CODE LETTER DESIGNATES DRILLED SHANK ONLY.
EXAMPLE OF PART NUMBER:
NAS1 003-8 = .1 900 DIAMETER BOLT, .500 GRIP, DRILLED SHANK ONLY.
NAS1 003-8A = .1 900 DIAMETER BOLT, .500 GRIP, UNDRILLED.
NAS1 003-8H = .1 900 DIAMETER BOLT, .500 GRIP, DRILLED HEAD ONLY.
NOTES: (1 ) REFERENCE DIMENSIONS ARE FOR DESIGN PURPOSES ONLY AND NOT AN INSPECTION REQUIREMENT.
(2) MAGNETIC PERMEABILITY SHALL BE LESS THAN 2.0 (AIR= 1 .0) FOR A FIELD STRENGTH H = 200 OERSTEDS USING A MAGNETIC PERMEABILITY INDICATOR PER ASTM A 342/A 342M, TEST METHOD 3.
(3) REMOVE ALL BURRS AND SHARP EDGES.
(4) THESE BOLTS ARE INTENDED FOR USE AT TEMPERATURES UP TO 1 200°F.
/5/ GRIP LENGTH: FROM UNDERSIDE OF HEAD TO END OF FULL CYLINDRICAL PORTION OF SHANK.
/6/ COTTER PIN HOLE CENTERLINE: WITHIN .01 0 AND NORMAL WITHIN 2° OF BOLT CENTERLINE.
/7/ “ØH” MAXIMUM NOT TO EXCEED “B”; MINIMUM DIA AT TOP OF HEAD NOT LESS THAN “ØH.”
/8/ CONCENTRICITY: “ØH” AND “ØA” WITHIN “X” VALUES FIM, “ØA” AND THREAD PITCH DIAMETER WITHIN “Y” VALUES FIM.
/9/ SHANK STRAIGHTNESS: WITHIN “Z” VALUES FIM PER INCH OF LENGTH.
/1 0/ BEARING SURFACE SQUARENESS: WITHIN .003 FIM WITH SHANK.
(1 1 ) DIMENSIONS IN INCHES: TOLERANCES UNLESS OTHERWISE SPECIFIED: ANGLES ±5°.
(1 2) PARTS MANUFACTURED TO AMS7478 MAY BE FURNISHED FROM SUPPLIERS STOCK UNTIL DECEMBER 31 , 1 992.
/1 3/ ULTIMATE TENSILE STRENGTH IS BASED ON A NON-DRILLED FED-STD-H28/2 THREAD AREA AND 1 40,000 PSI. FOR BOLTS WITH CROSS-DRILLED THREAD, A REDUCED SECTION SPECIMEN MAY BE MACHINED FROM THE PART AND TESTED TO VERIFY THAT BASIC MATERIAL PROPERTIES MEET OR EXCEED 1 40,000 PSI MINIMUM.
/1 4/ DISCALOY INACTIVE FOR DESIGN AFTER JULY 1 , 1 979.
/1 5/ NAS1 01 6A INACTIVE FOR DESIGN AFTER JULY 1 , 1 979.
/1 6/ DASH NUMBER INDICATES GRIP LENGTH IN .0625 INCREMENTS. INTERMEDIATE OR LONGER
LENGTHS MAY BE ORDERED BY USE OF PROPER DASH NUMBER.
(1 7) FOR DESCRIPTION OF STATUS NOTES, SEE NAS380.
(1 8) THIS STANDARD TAKES PRECEDENCE OVER DOCUMENTS REFERENCED HEREIN.
(1 9) REFERENCED DOCUMENTS SHALL BE THE ISSUE IN EFFECT ON DATE OF INVITATIONS FOR BID.
(20) UNLESS OTHERWISE SPECIFIED, PART INVENTORY MANUFACTURED TO PREVIOUS REVISIONS OF THE APPLICABLE DRAWING OR SPECIFICATION MAY BE PROCURED AND USED UNTIL STOCK IS DEPLETED.
PROCUREMENT SPECIFICATION:
AS7477 EXCEPT AS NOTED. ULTIMATE TENSILE STRENGTH (LBS. MIN.) LOAD VALUES AS TABULATED HEREIN.
