Hex Head Bolts 1/4×21/2 5.6 BSF
Hex head bolts and fasteners are used in a range of applications, especially for fastenings wood, steel, and other construction materials. They are ideal for docks, bridges, highway structures, building projects, repair, and construction work. As the name implies, they have a hexagonal head and come with machine threads for a firm and rough handling. They come in a wide range of different hex bolt sizes for custom applications depending on its dimensional requirements.nA bolt is a type of fastener, usually made from metal, that commonly comprises a head at one end, a chamfer at the other, and a shaft characterised by an external helical ridge known as a ‘thread’. Bolts are typically used to hold materials or objects together, or to position objects.nBolts provide a tremendous amount of holding strength whereas screws offer a middle ground for holding power. Light to medium construction projects, like for fencing or framing, are best for screws. Your heavy-duty projects are best for bolts.nTypically, a bolt is tensioned (preloaded) by the application of a torque to either the bolt head or the nut. The applied torque causes the bolt to “climb” the thread causing a tensioning of the bolt and an equivalent compression in the components being fastened by the bolt.n A typical rule of thumb – Use a bolt diameter that is 1.5 – 2.5 times (up to three times) the thickness of the thinner material you are bolting together. So, for 6mm material, a 16mm diameter is often a good bolt choice.
