High quality Bolt is offered by China manufacturer Gangtong Zheli. A bolt is a type of fastener that comprises a head and a threaded shaft. Bolts are used in conjunction with nuts to securely join and connect two components with through holes. They come in various head shapes, including hexagonal, round, square, and countersunk heads. Examples of bolt types include hexagonal bolts, carriage bolts, hexagon socket bolts, T-bolts, flange bolts, countersunk bolts, and square head bolts.
Bolts are categorized into different performance grades, based on the material used, with carbon steel and alloy steel being the most common. These grades include 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, and 12.9. Bolts with grades of 8.8 and higher are considered high-strength bolts and are made from low-carbon alloy steel or medium carbon steel, which undergoes heat treatment (quenching and tempering). Bolts with lower grades are generally referred to as ordinary bolts. The performance grade of a bolt is indicated by a two-number label, representing the nominal tensile strength value and the yield ratio of the bolt material.
Stainless steel bolts are classified into various groups, such as A1, A2, A3, A4, and A5, each with its own subgrades (e.g., A1-50, A2-70). The first letter and number denote the stainless steel group, while the second and third numbers represent one-tenth of the tensile strength.
These specifications and classifications help users select the appropriate bolt for their specific applications, ensuring the bolts meet the required strength and performance standards.
