Stainless Steel 304 316 M20 X 90mm Hex Head Bolts and Nuts with washers
1.Product Description
Hex 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. Be used to structure connections, especially in construction and as well as to fix wooden secitons in furniture manufacture. Selected type of thread depends on the thickness of connected elements. Hex bolts features full threaded and partial threaded and the partial threaded bolt is weighter than full threaded in the same size, and the two type is high tensile for fasten. Commonly the hex bolt fix with washers and nut to help for the fastening.
