COATED BOLTS – ALUMINUM COATING PER NAS4006.
CODE: ADD “A” AFTER BASIC NUMBER FOR ALUMINUM COATED BOLTS. MAY BE USED WITH “D”, “H”, “L” OR “P” CODE.
ADD “D” AFTER BASIC NUMBER FOR DRILLED SHANK BOLTS. DO NOT USE WITH “L” OR “P” CODE. /1 3/
ADD “H” AFTER BASIC NUMBER FOR BOLT WITH DRILLED HEAD. DO NOT USE WITH “L” OR “P” CODE.
ADD “L” AFTER BASIC NUMBER FOR SELF-LOCKING BOLT WITH LOCKING ELEMENT TYPE OPTIONAL;
SEE PROCUREMENT SPEC BELOW. DO NOT USE “L” WITH “D”, “H” OR “P” CODE.
ADD “P” AFTER BASIC NUMBER FOR SELF-LOCKING BOLT WITH PATCH TYPE LOCKING ELEMENT ONLY;
SEE PROCUREMENT SPEC BELOW. DO NOT USE “P” WITH “D”, “H” OR “L” CODE.
ADD “U” AFTER BASIC NUMBER FOR UNPLATED BOLT. MAY BE USED WITH “D”, “H”, “L” OR “P” CODE.
GRIP DASH NUMBER INDICATES GRIP IN .0625 INCREMENTS (CONVERTED TO THREE DECIMAL PLACES PER ANSI Y1 4.5-1 982). SEE TABLE II FOR TABULATIONS OF GRIP AND LENGTH DIMENSIONS.
/1 7/
CODE LETTER “X” AND “Y” FOLLOWING THE GRIP DASH NUMBER INDICATES REPLACEMENT OVERSIZE REPAIR BOLT. (SEE LAST SHEET)
IF MORE THAN ONE CODE LETTER IS USED IN SEQUENCE, ARRANGE THE LETTERS ALPHABETICALLY.
EXAMPLE OF PART NUMBER: (SEE LAST SHEET FOR OVERSIZE BOLTS.)

NOTES:
/1 / GRIP LENGTH: FROM UNDER SIDE OF HEAD TO END OF FULL CYLINDRICAL PORTION OF SHANK.
/2/ BEARING SURFACE SQUARENESS: WITHIN .003 FIM OF “ØD”.
/3/ “ØC” MAX NOT TO EXCEED ACTUAL WIDTH ACROSS FLATS; MIN AS TABULATED IN TABLE I.
/4/ “ØP” HOLE CENTERLINE WITHIN .01 0 AND NORMAL WITHIN 2º OF BOLT CENTERLINE.
/5/ REFERENCE DIMENSIONS ARE FOR DESIGN PURPOSES ONLY AND ARE NOT AN INSPECTION REQUIREMENT.
/6/ CONCENTRICITY: “ØC” AND “ØD” WITHIN “X” VALUES FIM. “ØD” AND MAJOR THREAD DIA WITHIN Y VALUES FIM.
/7/ SHANK STRAIGHTNESS: WITHIN “Z” VALUES FIM PER INCH OF LENGTH.
/8/ TOP OF HEAD SHALL BE FLAT ON THE 1 .1 250-1 2 AND 1 .2500-1 2 SIZE BOLTS.
/9/ PROTRUSION OF LOCKING ELEMENT SHALL BE CONTROLLED SO THAT IT WILL PASS FREELY, OR WITH FINGER PRESSURE, THROUGH A RING GAGE WITH DIAMETER OF .01 0 (+.001 , -.000) GREATER THAN MAXIMUM MAJOR DIAMETER OF BOLT THREAD.
