Eye Bolt Has A Fixed Role

Eye Bolt are widely used in machine construction for detachable connections and are generally used in conjunction with nuts (usually with a washer or two washers).

Screws are usually used alone (sometimes with washers), generally fastened or tightened, should be screwed into the body of the internal thread.

Studs are mostly used to connect one of the connected parts to a large thickness, requiring a compact structure or where the connection is frequent and not bolted. The studs are generally threaded at both ends (single-ended studs are single-ended with threads). Typically, one thread is screwed into the body of the body and the other end is matched to the nut. It acts as a connection and fastening. To a large extent also has a fixed role.

Wood screws are used to screw into the wood, from the connection or fastening effect.

With the tapping screw to match the working screw hole without pre-tapping, screwing into the tapping screw at the same time, so that the internal thread forming.

The pins are usually used for positioning, can also be used to connect or lock parts, but also as a safety device in the overload cut components.

The rivet has a head at one end and no threads on the stem. When used, insert the stem into the hole of the connector, and then rivet the end of the rod, from the connection or fastening effect.

 Connect a pair of screws or Eye Bolt or a combination of tapping screws and washers. After the washer is attached to the screw, it must be free to rotate on the screw (or bolt) without falling off. Mainly from the fastening or tightening effect.

Identify varieties

(1) the principle of selection of varieties

① from the processing and assembly work efficiency considerations, in the same machinery or engineering, should minimize the use of fasteners varieties;

② from the economic considerations, should give priority to the use of commodity fastener varieties.

③ According to the expected requirements of the use of fasteners, according to type, mechanical properties, precision and thread to determine the selection of varieties.

(2) type

① Eye Bolt

a) general purpose Eye Bolt: a lot of varieties, there are hexagonal and square head of the points. Hexagon head Eye Bolt are the most common, and are divided into A, B, C and other product grades according to the manufacturing precision and product quality. They are the most widely used in A and B, and are mainly used for important, high precision and high impact, vibration or Variable load place. Hexagon head Eye Bolt according to their head support area size and installation location size, can be divided into hexagonal head and large hexagon head two; head or screw with a variety of holes for the need to use when locking. The square head of the square head has a larger size and force surface, easy to catch the mouth of the wrench or rely on other parts from the beginning and rest, commonly used in the relatively rough structure, and sometimes used in T-slot, easy to bolt Loose position in the slot. See GB8, GB5780 ~ 5790 and so on.

b) Hinged hole with the bolt: the use of Eye Bolt will be tightly fitted into the hinge hole to prevent the workpiece misalignment, see GB27 and so on.

c) stop Eye Bolt: a square neck, with the tenon of the points, see GB12 ~ 15;

d) Special purpose Eye Bolt: T-slot Eye Bolt, Eye Bolt and anchor Eye Bolt. T-slot Eye Bolt are used for places where frequent connections are required; anchor Eye Bolt are used to secure the rack or motor base in a cement foundation. See GB798, GB799 and so on;

e) High strength Eye Bolt for steel structures Connection: For general applications such as buildings, bridges, towers, pipe supports and hoisting machinery for steel structures, see GB3632 and so on.
