The design of the Superior Grip Hexagon Head Bolt is quite simple: it is basically a threaded rod with a hexagonal head at one end. Most of the rod body is threaded to enable it to be screwed into nuts or threaded holes. The head is slightly wider than the rod body, which makes it easier for a wrench to grip. Some heads have flat sections below them to distribute pressure; others have sloping edges to avoid piercing the material. This design is simple in structure, low in production cost, and convenient to use - that's why you can find this type of bolt being used almost everywhere.
Superior Grip Hexagon Head Bolt come in different colors depending on their coating. The surface of galvanized bolts is glossy, the main body is silver-gray, and in some cases it has a slight yellowish tint. Compared with pure steel bolts, the zinc coating on its surface can provide better moisture resistance and has a wider range of applicability. For outdoor or areas near water sources, hot-dip galvanized bolts have a rough, dark gray surface and can maintain their appearance for a longer time.The surface also has a black oxide layer, giving it a dark gray or black appearance. This reduces glare and provides some rust resistance. Therefore, the color of the bolt is not only for aesthetics but also indicates its optimal location and estimated service life.
