Mechanical Properties

Samples taken from product (see the section in Specification A962/A962M titled “Mechanical Properties”) shall conform to the mechanical properties of Tables 2-4.

Age hardened bolting material shall be capable of meeting the requirements prescribed in Table 3. Impact testing is required when S1 is invoked in the purchase order or contract.

Number of Tests:
Bolting Material— See 8.4 for hardness testing of bar. See the section in Specification A962/A962M titled “Number of Tests” for all other tests except those covered in 8.3.2.
Full Size Bolting Components— Headed bolts with a 1 1 ⁄ 2 in. [37 mm] body diameter and smaller, with a body length three times the diameter or longer and a required maximum tensile load of 160 000 lb/f [705 kN], produced by upsetting or forging (hot or cold) shall be subjected to full size testing. The testing shall be in addition to the tensile testing specified in above Bolting Point. The lot size shall be as shown in Specification A962/A962M (see the section titled Number of Tests). Failure shall occur in the body or threaded section with no failure, or indications of failure, such as cracks, at the junction of the head and shank. Wedge tensile testing is not required for flat countersunk head or socket button products.

Hardness Test:
Bolting Material Bars 2 in. [50 mm] and Over— One test on each mill-treated length.
Bolting Material Bars Under 2 in. [50 mm]— One test on at least 10 % of the mill treated lengths.
