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.?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 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.
