B18.31.1M Metric continuous-Threaded studs / Staninless Steel ASTM A193 B8M Stud Bolt
Studs come in a variety of sizes and materials. These studs are used in all aspects of construction and mechanical engineering. They are made of materials such as stainless steel, aluminum, nylon and carbon steel. Various types of studs are used for specific products, each requiring specific materials.
There are two types of double-headed bolts in common use (also known as all-thread studs), with two types of threads: coarse threads with M and nominal diameter, and fine threads with M and nominal diameter x pitch.
