Carbon Steel Hot Dip Galvanized DIN933 DIN931 ASTM A325 A490 ISO4041 Heavy Hex Head Bolts

Carbon Steel Hot Dip Galvanized DIN933 DIN931 ASTM A325 A490 ISO4041 Heavy Hex Head Bolts

Description:

Hex bolts with a nut and two washers, have hexagonal heads and machine threads. Also known as hex cap screws or machine bolts, or hex tap bolts. Class 10.9 steel is an alloy steel that has been quenched and tempered, according to ASTM International standard ASTM F568M. offers corrosion resistance and lubricity. Zinc plating offers corrosion resistance and protection.Hexagonal bolt head and the screw fastener means consisting of bolts Material iron bolts and stainless steel bolts, hex head bolts namely (threaded portion) -C grade and hex head bolt (full thread) -C grade, also known as hex head bolt (crude) gross hex head bolts, black iron screws. The hex bolt has other name, such as hex head bolt, machine bolt, hex head cap screw, and so on.
Steel bolted performance rating 3.6,4.6,4.8,5.6,6.8,8.8,9.8,10.9,12.9 more than 10 levels, of which 8.8 and above bolts made of carbon steel or carbon steel and heat treated (quenching and tempering), commonly known as high strength bolts, the rest is known as ordinary bolts. Bolt performance rating label has two parts numbers, respectively, said male bolt material tensile strength and yield strength ratio.
Hexagonal bolt head and the screw fastener means consisting of bolts Material iron bolts and stainless steel bolts. Divided by grade iron bolt 4.8, 8.8 bolts. The HDG hot dip galvanized hex head bolts are in better anti-corrison. The external hex drive has six flat sides that a wrench can grip to turn the screw from the side, enabling use when there is no space above the head for a driver.
HDG also known as hot-dip galvanizing is a method of metal coating layer steel structures immersed in the molten zinc was obtained. In recent years, with the high-voltage transmission, transportation, communications industry rapid development, protection of the steel parts have become increasingly demanding, HDG demand is also increasing.
