Standard parts for high strength screws include?


1.bolt: by the head and screw (with external thread of the cylinder) two parts of a class of fasteners, need to cooperate with the nut, used to fasten the connection of two parts with a through hole. This form of connection is called bolt connection. If the nut is screwed down from the bolt, there can make the two parts apart, so the bolt connection is a removable connection.

2. stud: no head, only the two ends are external threads of a class of fasteners. When connected, one end of it must be screwed into the parts with internal threaded holes, the other end through the parts with through holes, and then screwed on the nut, even if the two
The two parts are fastened together to form a whole. This form of connection is known as the stud connection, is also a removable connection, mainly used for dry connected parts of a large thickness, requiring compact structure, or because of frequent disassembly, should not be used for bolted connections.

3. screw: also by the head and screw two parts of a class of fasteners, according to the use can be divided into three categories: machine screws, fastening screws and special purpose screws. Machine screws are mainly used for a tight threaded hole parts, with a through-hole parts of the fastening between the connection, without the need for a nut with (this form of connection is called screw connection, also belongs to the removable connection; can also be used with the nut, with a through-hole parts of the fastening between the connection.) Fixing screws are mainly used to fix the relative position between two parts. Special purpose screws, such as lifting ring screws, are used for lifting parts.

4. nuts: with internal threaded holes, the shape is generally shown as a flat hexagonal column, there is also a flat square column or flat cylindrical, with bolts, studs or machine screws, with dry fastening connection between two parts, so that it becomes a teaching body

5. Self-tapping screws: similar to machine screws, Bur screw on the cap pattern for special white tapping screws with threads, with dry vertical fastening connected two Pope's Jinya components, so that it becomes a whole, components on zero to make a small hole in advance, by dry this tent
Nails and have a high hardness, can be directly screwed into the holes of the components, so that the components form a response to the internal threads, this form of connection is also a detachable connection

6. wood screws: is also similar to machine screws, but the thread on the screw for the special wood earring nail with ribbing, can be directly applied to the wooden components (or parts), with a dry with a through hole in the gold house (or non-gold house) parts and a wooden components tightly
A solid connection is made. This connection is also a removable connection.

7. hot corner: shape is flat circular a meter fastener, Kwik dry bolt, screw or cap mother of the support surface and connected parts between the surface, play a role in increasing the contact surface surface of the connected parts and, reduce the unit surface and pressure and protect the connected multipliers
Surface is not damaged; another type of elastic washer, can also play a role in preventing the nut back loose.

8. retaining ring: for installation in the machine. Equipment shaft groove or hole groove, play a role in preventing the shaft or hole on the parts to move around.

9. pin: mainly for parts positioning with, some can also be connected to parts, fixed parts, transfer power or lock other fasteners with.

10. rivet: by the head and nail rod of two parts of a meter tight with the piece, with dry fastening connection of two parts with through holes (or components), so that it becomes a save body, this connection form called riveted connection, referred to as riveting, is not removable with
This form of connection is called riveted connection, or riveted connection, and is not removable, because to separate the two parts connected together, the rivets must be destroyed on the variable parts.

11. combination of parts and connection vice: combination of parts refers to the combination of the supply of a class of fasteners, such as the beginning of its kind of machine screws (or bolts, since the supply of screws) and flat hot ring (or bullet arrow hot ring, locking hot round) combination of supply: connection vice refers to pick up the heavy kind of special cap bolts

Nuts and washers combined supply of a class of fasteners, such as steel structures with high-strength large hexagonal head bolts connecting vice

12. afflicted nail: by the dry light can and nail head (or no nail head) is composed of m fasteners, with sex connection method to connect him fixed in a part (or member) above, in order to connect with other parts again
