DIN933 A2-70 / 304 Stainaless Steel Hex head bolts with nut and washer, cup screw bolts

Description:

Hex bolts, also called hexagon screw head bolts, hex cap bolts, hex-cap screws, or machine bolts, are a very common choice when it comes to construction and repair.Stainless steel Bolts is one type of fully threaded tap bolts, come with a stem that is fully threaded from the base up to the head, and an underhead washers bearing surface. As the name suggests, hex bolts have hex (short for "hexagon") heads and may have a washer face bearing surface, as described above. Hex heads have six flat sides and are also called "6 point" .

There are two threaded of hex bolts,it is UNC threaded ( Unifield National Coarse ) and UNF threaded ( Unifield National Fined). Fine threaded fasteners have more threads per inch than Couarse threaded fasteners because coarse threads are father apart.

Every different hex bolt material has particular properties to fit specific applications. Hexagon cup head bolts are made from a variety of materials to accommodate the wide range of applications in which hex cap bolts are used. Material available: stainless steel ,carbon steel, alloy steel with high tensle.

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.Different form a tapping screw, tap bolts are designed to be inserted through holes in assembled parts, sine these do not have their own mating internal threads and are tightened by torqueing the head.

Hex head bolts can be used for various different applications that include fastening steel, wood and other construction materials for projects such as highway structures,briges, docks, and buildings. Hex bolts with forged heads are also commonly used as headed anchor bolts.Hex bolts has six sided headare the industry standard for fasteners with forged heads.

Application:

Hex bolts are used to fasten two or more parts together to form an assembly either because it cannot be manufactured as a single part or to allow for maintenance and repair disassembly.
