Product Description

Product Introduction of ANSI B18.2.3.7M Hex Bolt

Leader-Fastener® Hexagon bolts are a type of fastener consisting of a head and a screw (a cylinder with an external thread), which need to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Stainless steel bolts are made of stainless steel SUS201 bolts, SUS304 bolts, and SUS316 bolts. The performance grades of bolts for steel structure connection are divided into more than 10 grades such as 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. Among them, the bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel and are heat-treated (quenching, tempering), commonly known as high-strength bolts, the rest are commonly known as ordinary bolts. The bolt performance grade label consists of two parts of numbers, which represent the nominal tensile strength value and yield ratio of the bolt material respectively.
