Black Oxide Hex Head Bolts, High Tensile Carbon Steel Bolts M3 X 10 - M160 X 1000mm
1. 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.
Hex Head Bolts are designed for assembly into a hole. Hex Head Bolts according to SAE specifications with a designed washer face under the head and a chamfered point. Grade 9.8 has a greater tensile strength than Grade 8.8. Hexagonal bolt combined with head and the screw fastener, consisting of bolts Material iron bolts and stainless steel bolts, which can divided into full thread hex bolt and half thread hex bolt. Reasonably, these kinds of fasteners might be known as bolts, but according to the US government document Distinguishing Bolts from Screws products' standard.
The grade of the iron bolts are 4.8,5.6,6.8,8.8,9.8,10.9,12.9 etc, bolts Gr8.8 or above which is made of low carbon steel or carbon steel with heat treatment (quenching and tempering), normally named as high strength bolts, the rest is known as ordinary bolts. The stainless steel are A2, A4, SUS201 SUS304 SUS316 etc. Used with the nut for fastening two parts with tapped hole.

3. Applications:
Production process: wire rod, wire drawing, drawing, cold forging, threading, dipping, inspection, packing, shipment.The hex head bolts are be used in connecting.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.
