Introduction to Hex Bolts

Hexagonal bolts refer to fasteners composed of heads and screws. Bolts are divided into iron bolts and stainless steel bolts according to their materials, namely, hexagonal head bolts (partially threaded)-Class C and hexagonal head bolts(full threaded)-Class C. A type of fastener consisting of two parts: a screw and a screw (cylinder with external threads), which need to be matched with a nut to fasten and connect two parts with through holes

Hexagon bolts are six-sided bolts made of carbon steel, stainless steel, and alloy steel. They are often used in construction and maintenance applications. Some of the most common specifications include: ASTM A307A, A354 and F1554，hexagon bolts can be partially threaded or fully threaded. They are usually called self-tapping bolts. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection It is a detachable connection.

Hex bolt classification

Hexagon head bolts can be divided into two types: external hex bolts and internal hex screws. In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rod. These holes can make the bolt not loose when it is vibrated. Take off.

According to the force mode of the connection, there are ordinary and reamed holes. The bolts used for reaming holes should be matched with the size of the hole and used when subjected to lateral forces.
According to the shape of the head, there are hexagonal heads, round heads, square heads, countersunk heads, and so on. Generally, countersunk heads are used in places where the surface after connection is required to be smoothwithout protrusions, because the countersunk head can be screwed into the part. The head can also be screwed into the part. The tightening force of the square head can be larger, but the size is large. The hexagonal head is the most commonly used.

Hex bolt description

Hexagon bolts are six-sided bolts made of carbon steel, stainless steel, and alloy steel, often used in construction and maintenance applications. Some of the most common specifications include: ASTM A307A, A354 and F1554. Hexagon bolts can be partially threaded or fully threaded, and are usually called self-tapping bolts.

Hexagon bolts have a hexagon head and machine threads for use with nuts or in threaded holes. Also called hex cap screws or machine bolts.

The hexagon head cap screw is a six-sided bolt with a trimmed hexagon head and a washer surface on the bearing surface. …Hex cap screws are usually used in OEM applications that require precise tolerances.

Hexagon bolts can be used for many different applications, including fastening wood, steel, and other materials used in engineering, such as docks, bridges, highway structures, and buildings. Hexagon bolts with forged heads are also commonly used as anchor bolts with heads.
