Different names, natural performance is different, usually high-strength bolts can bear the same load than ordinary bolts larger.
Уобичајени материјал за вијке је произведен К235 (тј. А3).
Високе чврстоће резу material 45 # steel, alloy steel (such as 20MnTiB, 35VB) or other high-quality materials, made after the heat treatment, increased strength.
Разлика између њих двоје је разлика у чврстоћа материјала.
The first point: from raw materials to analyze:
High-strength bolts made of high-strength materials. High-strength bolts, nuts and washers are made of high strength steel, commonly used 45 steel, 40 boron steel, 20 manganese titanium boron steel. Common Q235 steel завртњи commonly used in manufacturing.
The second point: From the intensity level point of view:
Commonly used 8.8 and 10.9 two intensity levels, of which 10.9 majority. Normal резу strength level is low, usually 4.4, 4.8, 5.6. (8.8S and 10.9S for steel structure only)
