Steel Hexagon Screw Head Bolts Hex Cap Bolts For Construction Automobile Engineering Industries

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.

	Hexagon Bolts With Wire Hole On Head		GB32-76	6~48	10~300
	Small Hexagon Bolts With Wire Hole On Head		GB25-76	8~48	10~300
	Slotted Hexagon Head Bolts		GB29-76	3~12	4~200
	Hexagon Head Bolt With Guide Neck		GB22-76	8~36	30~300	Used for occasions with good alignment requirements, the pad circle will not deviate to one side.
	Small Hexagon Head Bolt With Fit Neck And Hole		GB24-76	8~36	30～300
	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.
Square Head	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	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
	Half Round Head Wedge Bolt (rough)		GB13-76	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.
