What does A2-70 on a bolt mean?
The “70” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Therefore, A2-70 is an austenitic, acid proof stainless grade (usually 304 material – 304 or 304L) which has been cold worked to provide a minimum tensile strength of 700N/mm² (MPa).

What does A2 mean on a bolt?
A2 stainless steel fixings are made from an alloy containing a mixture of two or more metals. The steel within the fixing must contain at least 10.5% chromium to be considered or called stainless, and this chromium makes the metal more corrosion resistant and less likely to stain than other steels.
Is A2-70 bolt metric?
M4-0.70 Metric Grade A2-70 Stainless Steel Machine Screw Hex Nuts (25-Pack)
What is stronger A2 or A4 stainless steel?
A2 vs A4 stainless steel strength Whereas grade A4 is stronger than grade A2, and its tensile properties are almost similar to alloy steel grade 8.8.
Is A2 stainless steel the same as 304?
A2 stainless steel is often referred to as 304 or 18/8 Stainless. 18/8 actually refers to the amount of chromium and nickel in the alloy – 18% chromium and 8% nickel. A2 (304, 18/8) is an austenitic steel and is non-magnetic. The chromium provides a corrosion and oxidation resistance, however it can tarnish.
What does A4 70 mean on a bolt?
The “70” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Therefore, A4-70 is an austenitic, acid proof stainless grade (usually 316 material – 316 or 316L) which has been cold worked to provide a nimimum tensile strength of 700N/mm² (MPa).
What is the strongest stainless steel bolt?
BUMAX® Ultra
BUMAX® Ultra has proven itself as the world’s strongest bolt – in various highly-demanding critical fastener applications around the world where standard fasteners are simply inadequate.
Is A2 stainless steel good?
A2 grade stainless steel is also often referred to as type 304 or 18/8 – this latter label denotes the fact that A2 grade stainless steel containing approximately 8% nickel and 18% chromium. With a high hardness level and consistent dimensional stability, A2 stainless steel shows good resistance to wear & tear.
What size is an A2 screw?
A2-70 Stainless Hexagon Socket Screw, Type : Cap Head, Thread Size : M4, Bolt Length : 20mm, Thread Length : 20mm [per Pk/50]
Is A2 or A4 stainless stronger?
Is A2 stainless steel strong?
Stainless steel fasteners are also often created from A2 stainless steel as the metal offers strong abrasion resistance, good resistance to corrosion and reliably low levels of distortion.
Does A2 steel rust?
Does A2 steel rust? Yes, A2 steel composition has only 5.5% of chromium, which grants him good rust protection but it’s not completely immune.
What is the difference between A2 70 and A4-70?
The material composition is the primary difference that makes difference in the mechanical properties and other aspects of these materials. The a4 material has 16% chromium, 2% molybdenum and 10.5% nickel in the composition. The a2 material has 10.5% chromium in the composition.
