DIN603 A2-70 / 304 / Stainless Steel Carriage bolts , mushroom round head with neck
Carriage bolt also called Round Heads and Square Necks, it is a threaded bolt with a round, smooth head. The bolt is prevented from rotating in its hole by a square neck directly under the head.A carriage bolt is a type of threaded fastener designed to be use from woods, although specialized versions can be used t obe fasten metal components. They are usually made from various types of stainless steel carbon steel, for strength and durability, though other materials can be used to make them as well.
The design of a carriage bolt includes a mushroom round, domed head with an externally threaded bolt projecting from it. The head is typically at least twice the diameter of the bolt shaft, and usually does not have slots for a screwdriver or other driving device. In a variation on the basic carriage bolt, the square fitting under the rounded head is replaced with ribbing that holds the bolt in place when it is used with other metal components.Stardard DIN0603, stainless steel carriage bolts, The length of the bolt itself will vary according to its intended use, as will the diameter of the bolt and bolt head, regardless of the type of materials being fastened.
The thread size of the bolt must match the thread size of the nuts because be screwed on properly; thread sizes can vary significantly according to application. Specialized all kinds of the bolt and nut combination may be made from metals such as galvanized steel that resist corrosion so they can be used in wet environments or places in which the bolt is likely to be exposed to corrosive chemicals. The wide head — sometimes called a cup or mushroom head — is ideal for use with timber, where its large size prevents it from being pulled deeply into the wood without the need of a washer, although they can be used.

Pieces of timber are often secured together using one or two carriage bolts during construction of homes, outdoor decks. These bolts are commonly used in chain link fences, patio and ready-to-assemble furniture, machinery assembly, and even in automobiles. Since the square neck keeps the bolt from turning, carriage bolts are a good choice for situations in which the head of the bolt cannot be easily accessed.
