	熱處理或狀态	抗拉強度 σ_b ksi	屈服點 σ_s ksi	斷後伸長率或延伸率 δ %	硬度 HBW
1/4 ~ 1-1/2 (全尺寸)	H	110~140	≥90		HR (C20~30)
1/4 ~ 1-1/2 (全尺寸)	HT	160~190	≥120		HR (C34~45)
1/4 ~ 1-1/2 (機加工)	H	≥110	≥90	≥18
1/4 ~ 1-1/2 (機加工)	HT	≥160	≥120	≥12

注1： “全尺寸”指的拉力測試試件是使用前的狀态未經改變的完整的緊固件產品。
注2：A——Machined from annealed or solution-annealed stock thus retaining the properties of the original material, or hot-formed and solution-annealed.
AF——Headed and rolled from annealed stock and then reannealed.
AH——Solution annealed and age-hardened after forming.
CW——Headed and rolled from annealed stock thus acquining a degree of cold work; sizes 0.75 in. and larger may be hot worked and solution-annealed.
H——Hardened and tempered at 1050°F (565℃) minimum.
HT——Hardened and tempered at 525°F (274℃) minimum.
SH——Machined from strain hardened stock or cold-worked to develop the specified properties.
