hex bolt grade 8.8-10.9

Description

Hex bolts Gr 8.8-10.9 can be used for many different applications. That include fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings. Hex bolts with forged heads are also commonly used as headed anchor bolts.

Hence these hexagon head screws with fully threaded along the entire length according to DIN 933, BS3692, ISO4190, ISO898-1, ISO 4017. Available in Black Oxide, HDG, Electro Galva B633, Cadmium Plated, are readily available off the shelf.

General:

Meanwhile International Standard specifies the characteristics of hexagon head bolts with threads from M1,6 up to and including M64. Of product grade A for threads M1,6 to M24 and nominal lengths up to and including 10d or 150 mm, whichever is the shorter. And product grade B for threads over M24 or nominal lengths over 10d. Bolts are often used to make a bolted joint. Furthermore this is a combination of the nut applying an axial clamping force and also the shank of the bolt acting as a dowel.Pinning the joint against sideways shear forces. For this reason, many bolts have a plain unthreaded shank (called the grip length) as this makes for a better, stronger dowel. Whereas the presence of the unthreaded shank has often been given as characteristic of bolts vs. screws, but this is incidental to its use, rather than defining.
