M8 - 1.0 X 50mm Class 8.8 Hex Head Bolts , Hardened Metric Hexagon Bolts Bulk
1. Description:
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 3.6,4.6,4.8,5.6,6.8,8.8,9.8,10.9,12.9 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 SUS201 SUS304 SUS316 etc. Used with the nut for fastening two parts with hole.
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.
2. Specifications:
1. Name: DIN933 hex head bolt, stainless steel bolt, full threaded

8. Class: 4.8 6.8 8.8 10.9 12.9
3. Applications:
Hexagonal bolts: a two-part type
fasteners, to be with the nut and the screw head with the
(externally threaded cylinder) for fastening two parts with hole.
This connection type called bolt connection. As to unscrew the nuts from the bolts, so that the two parts can be separated, so bolting belongs detachable connection.
The hex head bolts are be used in connecting.

5. Advantages:
Stainless steel screws do not necessarily corrode rust, only that stainless steel screws are more likely to rust than iron screws.But stainless steel screws will rust in certain situations.So stainless steel screw in what condition easy to cause rusting!
Stainless steel screw has good characteristics, strong corrosion resistance, high temperature resistance, and strong rust resistance.But it will rust in harsh conditions.For example, stainless steel screws in very wet conditions, daily sun exposure, wind and rain.It will be a little rusty for a long time.Contact with some acid-base chemicals to produce chemical reactions.Cause corrosion to rust.There is already a bad stainless steel screws, such as material for stainless steel SUS201 screws to use the product in the water of the sea, because often time of soaking, originally SUS201 stainless steel screw itself is not very suitable for the water of the sea salt resistant used above.Cause corrosion to rust.The use of seawater products is generally recommended to use stainless steel SUS316 screws, because 316 stainless steel screws can carry corrosion and other performance is better.
