Grades used
​
Imperial Steel
Grade 2 - Low or medium carbon steel -Standard steel grade for hardware; may have a manufacturer’s mark ot unmarked
Grade 5 - Medium carbon steel, quenched and tempered - also known as grade F, and is used in automotive applications. Bolts made from grade 5 steel feature 3 radial line heads.
Grade 8 - Medium carbon alloy steel, quenched and tempered- Bolts are harder than grade 5 and are used in demanding applications such as automotive suspensions and high stress environments. feature 6 radial line heads.
Alloy Steel - Grade A325 Carbon or Alloy Steel with or without Boron - Heat treated for extra strength, distinguished by their gray black finish.
​
​
Metric Steel
Class 8.8 - Medium carbon steel, quenched and tempered Sizes <16mm Proof Load MPa 580 - Yield Strength MPa 640 - Tensile Strength 800
Class 8.8 - Medium carbon steel, quenched and tempered Sizes >16mm to 72mm Proof Load MPa 600- Yield Strength MPa 660 - Tensile Strength 830
Class 10.9 Alloy steel, quenched and tempered Sizes 5mm - 100mm Proof Load MPa 830- Yield Strength MPa 940 - Tensile Strength 1040
Class 12.9 Alloy steel, quenched and tempered Sizes 1.6mm - 100mm Proof Load MPa 970- Yield Strength MPa 1100 - Tensile Strength 1220
​
Stainless markings vary. Most stainless is non-magnetic. Usually stamped A2-70. A4-70, A4-80
​
A2-70 - Tensile Strength min 700 - Yield Strength 0.2% Proof (MPa) min 450
A4-70 - Tensile Strength min 700 - Yield Strength 0.2% Proof (MPa) min 450
A4-80 - Tensile Strength min 800 - Yield Strength 0.2% Proof (MPa) min 600
​
High Grade Stainless 17-4 PH is a precipitation hardening martensitic stainless
17-4 H1150 - Tensile Strength min 135,000 - Yield Strength 0.2% Proof (PSI) min 105,000
