Heat treatment can be performed as needed to increase strength. | | Alloy Steel | usually adds elements such as chromium, nickel, and molybdenum to improve strength and high-temperature resistance, and is mostly used in demanding working environments. | | Stainless Steel | has good corrosion resistance and is suitable for humid or chemical environments. | | Aluminum alloy | It is lightweight and corrosion-resistant, and is suitable for applications where weight is required. | | Melting and casting | Select appropriate metal materials for melting and then cast into the basic shape of the bolt. | | Cold forging or hot forging | To improve the density and strength of the material, the initial forming of the bolt is usually cold forging or hot forging. | | Cutting | Includes mechanical processing processes such as turning and milling, which are used to form the shape of the screw, thread, and head. | | Heat treatment | Improve the mechanical properties of the bolt through quenching, tempering, etc., and improve its strength and durability. | | Surface treatment | In order to improve corrosion resistance or appearance, the bolt is often galvanized, sprayed, or other surface treatment processes. | | Raw material preparation | Select appropriate metal materials, such as steel or alloy materials, and pass acceptance to ensure qualified quality. | | Forming | Use forging and other processes to process metal materials into semi-finished products close to the shape of bolts. | | Inspection and packaging | After strict quality inspection, qualified bolts are packaged and prepared for shipment. | | Hexagonal bolts | The most common shape, with a hexagonal head, is easy to install and remove with a wrench. | | Round head bolts | The head is round and is usually used in places with high visual requirements. | | Square head bolts | The head is square and suitable for installation in small spaces. | | Special bolts | Such as bolts with anti-theft design, or customized bolts for specific purposes. | | Category | [Socket Head Cap & Allen Screws](https://engineeringhardware.com/fastener-products/screws/socket-head-cap-allen-screws/) | ##
