10mm Stainaless Steel Hex Head Bolts , Security Allen BoltsFull Thread Grade10.9
1. Description:
Hex bolts has six sided headare the industry standard for fasteners with forged heads. 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 bolts are bolts with hexagonal heads and machine threads for use with a nut or in a tapped hole
Stainless steel Bolts as known as fully threaded tap bolts, come with a stem that is fully threaded from the base up to the head, and an underhead washers bearing surface. Different form a tapping screw, tap bolts are designed to be inserted through holes in assembled parts, sine these do not have their own mating internal threads and are tightened by torqueing the head.
Fully Threaded Tap Bolts that are either coarse or fine-threaded, in different lengths and diametersThe bolts have either cut or rolled screw threads that comply with the Unified system:UNC ( Unifield National Coarse ) and UNF ( Unifield National Fined). Fine threaded fasteners have more threads per inch than Couarse threaded fasteners because coarse threads are father apart. Hex bolts are not pointed whereas hex cap screws have a chamfered ( beveled ) point to protect the first thread from damage and to faciliate entry into an internally threaded part such as a nut or tapped hole.

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.
