8) THE VENDOR SHALL PERFORM AN ADDITIONAL RECEIPT INSPECTION OF THE BAR STOCK

CONSISTING OF A CHEMICAL TEST CONDUCTED ON ALL LOTS OF MATERIAL. THE CHEMICAL TEST

SHALL VERIFY THAT THE MATERIAL MEETS THE REQUIREMENTS OF QQ-N-286G. THE PRIMARY

SUPPLIER OR A SUBCONTRACTOR SHALL ACCOMPLISH THIS TESTING. TESTING AND RESULTS FROM

THE BAR STOCK SUPPLIER DOES NOT SATISFY THIS REQUIREMENT.

9) THE FOLLOWING EVALUATIONS SHALL BE PERFORMED ON 100% OF THESE FASTENERS:

A. HARDNESS TESTS

I. HARDNESS TESTS SHALL BE PERFORMED PER ASTM E-18, ROCKWELL C SCALE

(HRC) ON FASTENERS IN THE HEAT TREATED CONDITION. TEST METHODS OTHER

THAN ROCKWELL C ARE NOT PERMITTED WITHOUT PRIOR APPROVAL OF NFPC.

II. THREE HRC READINGS SHALL BE TAKEN AT EACH END AND AVERAGED. READINGS

ON THE POINT END SHALL BE TAKEN AT ½ RADIUS. ANY THREE LOCATIONS ON THE

HEAD END ARE ACCEPTABLE. ALL HARDNESS READINGS SHALL BE WITHIN THE

ACCEPTABLE RANGE. THE ACCEPTABLE IS HRC 25-35.

III. THE AVERAGED READINGS FROM EACH END OF EACH FASTENER SHALL BE

REPORTED, HOWEVER RESULTS DO NOT NEED TO BE IDENTIFIED TO SPECIFIC

PIECES. INDENTATIONS ON THE SURFACE OF THE FASTENERS ARE NOT REQUIRED

TO BE REMOVED.

B. LIQUID PENETRANT INSPECTION (PT)

I. PT SHALL BE CONDUCTED ON EACH ITEM PER MIL-DTL-1222 (SECTION 4.3.3,

METHODS PER NAVSEA T9074-AS-GIB-010/271), WITH THE FOLLOWING ADDITIONS

AND EXCEPTIONS:

SHALL BE STAMPED WITH THE MANUFACTURING LOT NUMBER ON THE POINT END AS

CERTIFICATION OF ACCEPTABILITY OF THE ABOVE HARDNESS, AND PT TESTS.

10) MIL-DTL-1222J REQUIRES WEDGE TENSILE TESTING AND YIELD STRENGH OF GRADE 500 HEX CAP SCREWS. ONLY THE SAMPLE SIZED REQUIRED BY MIL-DTL-1222J TABLES XI AND XII (PLAN C) ARE REQUIRED TO BE TESTED. THE FOLLOWING IS CLARIFICATION OF THE REQUIREMENTS FOR THESE

PARTICULAR HEX CAP SCREWS:

A. FINISHED BOLTS ARE REQUIRED TO BE WEDGE TESTED IAW MIL-DTL-1222J SECTION 4.5.2.3 (SECTION 3.5 OF ASTM F606). THE LOAD FOR THE TEST IS GREATER THAN 150,000 LBS AND SO THE PROVISIONS OF MIL-DTL-1222J SECTION 4.5.2.3 FOR MACHINE LIMITS APPLY. THIS IS

A DESTRUCTIVE TEST AND PARTS MAY NOT BE REWORKED AND SUPPLIED TO NFPC.

B. YIELD STRENGTH TESTS ARE REQUIRED IAW MIL-DTL-1222J SECTION 4.5.2.4 (METHOD 2 OR
