Hex Head Bolt Overview:
Bolt: A mechanical part, a cylindrical threaded fastener equipped
with a nut. A type of fastener consisting of a head and a screw
(cylinder with external threads). It needs to be matched with a nut
and is used to fasten and connect two parts with through holes.
This type of connection is called a bolt connection. If the nut is
unscrewed from the bolt, the two parts can be separated, so the
bolt connection is a detachable connection.
Product use: mechanical parts
Hex Head Stainless Steel Bolts Application:
Bolts are indispensable in daily life and in industrial production
manufacturing. Bolts are also called the rice of industry. It can
be seen that bolts are widely used. The application scope of bolts
includes: electronic products, machinery products, digital
products, power equipment, and electromechanical machinery
products. Bolts are also used in ships, vehicles, water conservancy
projects, and even chemical experiments.
Anyway, bolts are used in many places. Especially precision bolts
used in digital products. Micro bolts used in DVDs, cameras,
glasses, clocks, and electronics; general bolts used in
televisions, electrical products, musical instruments, furniture,
etc.; large bolts and nuts used in engineering, construction, and
bridges; transportation equipment, airplanes, trams, and
automobiles etc. Use both large and small bolts.

| Small Hexagon Head Bolts With Fit Neck And Hole Through The Shank | GB26-76 | 8~36 | 30~300 |
| Small Hexagon Fit Bolts | GB27-76 | 6~48 | 22～300 | It can accurately fix the mutual position of the connected parts,
and can withstand the shear and compression caused by lateral
forces. The deviations of dl include d4, ga and jc4 |
| Hexagon Fit Bolts With Split Pin Hole On Shank | GB28-76 | 6~48 | 22~300 |
| Square Head | Square Head Bolts (rough) | GB8-76 | 10~48 | 20～300 | The square head has a larger size, which makes it easier for the
wrench mouth to be stuck or against other parts to prevent
rotation. It is sometimes used in T-shaped slots and is often used
on some rough structures. |
| Small Square Head Bolt | GB35-76 | 5~48 | 10~300 |
| Countersunk Head | Countersunk Square Neck Bolts (rough) | GB10-76 | 6~20 | 25~200 | It is mostly used in places where the surface of the part needs to
be flat or smooth and does not prevent hanging things (the square
neck or wedge acts as a rotation stop) |
| Countersunk Head Wedge Bolts (rough) | GB11-76 | 6~24 | 25~200 |
| Half Round Head | Half Round Head Square Neck Bolts (rough) | GB12-76 | 6~20 | 16~200 | It is mostly used in places where the structure is restricted and
other bolt heads or parts cannot be used, and the surface is
required to be smooth. The semi-round head and square neck are
mostly used for metal parts, the large round head is used for
wooden parts, and the reinforced semi-round head is used for shock,
vibration and variable loads |
| Large Half Round Head Square Neck Bolts (rough) | GB14-76 | 6~24 | 20~200 |
| Cup Head Nib Bolts With Large Head (rough) | GB15-76 | 6~24 | 20～200 |

| T Slot | T Slot Bolts | GB37-76 | 5~48 | 25～300 | It is mostly used in places where bolts can only be connected from
one side of the connected part. At this time, the bolt is inserted
from the T-shaped hole of the connected part and the bolt is
rotated 90°. It is also used in places where the structure requires
compactness. |
| For hinges | Joint Bolt (rough) | GB798-76 | 4~36 | 20~300 | Mostly used in places and work equipment that need to be frequently
disassembled and connected. |
| Anchor | Anchor Bolt (rough) | GB799-76 | 6~48 | 80~1500 | Used for fixing racks in cement foundations. |
| Right Angle Anchor Bolt | Q/ZB185- 73 | 16~56 | 300~2600 |
| T-head Anchor Bolt | Q/ZB186- 73 | 24~64 | 200～1600 |
| Studs | Double End Stud Bolts (rough) | GB953-76 | 8~48 | 100~2500 | It is mostly used in places where the connected parts are too thick
to be connected by bolts, or where screws are not directly used due
to frequent disassembly, or where the structure requires a
relatively compact structure. |
| Double End Stud Bolts | GB901-76 | 2~56 | 10~480 | Generally, double-headed studs are used where one end needs to be
screwed into the probe hole to fix it. Double-headed probe posts of
equal length are equipped with nuts on both ends to connect the
parts. |
| Double Head Studs | L1=d | GB897-76 | 5~48 | 16~300 | |
| L1=1.25d | GB898-76 | 2~48 | 16~300 | |

| Welded Single-head Studs | GB902-76 | 6~20 | 16~300 | Used for connecting copper plates and thin parts. |
Note:
1. The small hexagonal head bolts produced by the cold heading
process have the advantages of high material utilization, high
production efficiency, and high mechanical properties. However, due
to the small size of the head, they are not suitable for multiple
assembly and disassembly, and the strength of the connected parts
is low and easy to install. Rust and other occasions.
2. When the grading regulations of mechanical properties (strength
level) cannot meet the usage requirements, materials can be
selected as needed. The materials of T-shaped, articulated and
other bolts are specified in the corresponding standards.
