Carriage bolts are round head square neck screws Generally speaking, bolts are used to connect two objects, usually through light holes, and need to be used in conjunction with nuts (nuts), and a single one does not work for connection. The tool is generally a wrench. The head is mostly hexagonal, generally larger. The carriage bolts are used in the grooves, and the square neck is stuck in the grooves during installation, which can prevent the bolts from rotating, and the carriage bolts can move in parallel in the grooves. Since the head of the carriage bolt is round, there is no design of available power tools such as cross recesses or inner hexagons, which can also play a role in preventing theft during the actual connection process.

Flange bolts: Flange bolts are integral bolts consisting of hexagon head and flange (the gasket under the hexagon and the hexagon are fixed together) and screw (cylinder with external thread), which need to be matched with the bolt. A bolted connection is a perceivable connection in order to assume the connection of parts through two holes.

Must. Teflon-coated bolts and nuts cannot be used separately, and must be combined to fasten and connect two through-holes, so Teflon-coated bolts and nuts must be combined. Teflon coatings can reduce product costs and improve production efficiency in many ways.

Hex bolt: A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. Hex Bolts This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments All kinds of fasteners can be seen on the , chemical industry, instruments and supplies, etc., which are the most widely used mechanical basic parts. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people also refer to a class of fasteners with existing national standards as standard fasteners, or simply as standard parts.

Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies.

The International Fastener Expo (IFE) is the largest B2B expo for fasteners, tooling, and machinery in North America.

There's a lucrative presence of manufacturers operating in the global assembly fastening tool market. These players are focusing on increasing their investments on R&D activities to improve the product quality to meet rising consumer requirements.
