DIN931 304 / 316 Stainaless Steel Hexagon head bolts with half threaded​

Description:

Hexagon headbolts, commonly called hex head cap screws, are bolts with a hexagonal or six sided head. Hex bolts has six sided headare the industry standard for fasteners with forged heads. Hex bolts, also called hexagon screw head bolts, hex head cap bolts, hex-cap screws,allen screw or machine bolts, are a very common choice when it comes to construction and repair.A hex cap screw is actually produced with tighter tolerances and can be used anywhere a hex head bolt is used. A common feature on a hex cap screw is a washer surface directly under the head which creates a better seal.

Each different about the hex head bolt material has particular properties to fit specific applications. Hexagon screw head bolts are made from many of materials to accommodate the wide range of applications in which hex bolts are used. Below are just a few of the more common types of hexagon screw head bolts for reference:

Stainless steel A2-70 304---The most common stainless steel for general hardware use for.

Stainless steel A4-70 316---A highly corrosion resistant grade of stainless steel. Ideal in salt water and chlorine environments. More expensive than A2-70304

Stainless steel Bolts come with a stem that is fully threaded from the base up to the head, and an underhead washers bearing surface.Hex bolts are bolts with hexagonal heads and machine threaded for use with a nut or in a tapped hole and washer. Different form a tapping screw, tap bolts are designed to be inserted through holes in assembled parts, because these do not have their own mating internal threads and are tightened by torqueing the head. Hex bolts are not pointed whereas hex cap screws have a chamfered ( beveled ) point to protect the first thread from damage and to faciliate entry into an internally threaded part such as a nut or tapped hole.

Because of its fully threaded body, this is used in many of applications such as in the vehicle repair industry when attaching a motor to a machinery. Also, these can be used with pulley to adjust the belt tension.

Application:

Hexagon head bolts can be used for a lot of different applications that include fastening wood, steel,  and other construction materials for projects such as briges, docks,highway structures,  buildings and so on. Hex bolts with forged heads are also commonly used as headed anchor bolts. Also uesd to fasten two or more parts together to form an assembly either.
