Product Description

Hexagonal bolts are a common type of fastener with various specifications and sizes, widely used in various machinery and structures. The following is a detailed description of the external hexagonal bolt:
Specifications and dimensions
Diameter: ranging from 5mm to 20mm.
Length: ranging from 8mm to 200mm.
Thread specifications: including metric, coarse, fine, and imperial.
Mechanical performance levels: including 4.8, 5.8, 6.8, 8.8, 9.8, 10.9, and 12.9 levels.
Surface Treatment
You can choose from various surface treatment methods such as natural color, galvanizing, blackening, and nickel plating.
Head size
The head size may also vary depending on the specifications.
Usage scenario
External hexagonal bolts are commonly used in situations that require a large pre tightening force, such as large equipment, due to their larger pre tightening contact area and higher pre tightening force.
It is also suitable for thin-walled parts or situations subjected to impact, vibration, or alternating loads.
Cost effectiveness
Compared to internal hexagon bolts, the manufacturing cost of external hexagon bolts is lower, especially in terms of head manufacturing cost.
The head of the external hexagonal bolt is relatively thin, and in some cases, the internal hexagonal bolt cannot replace the external hexagonal bolt.
Choose Suggestions
When selecting external hexagonal bolts, factors such as the required axial force at the tightening point, tightening space, and whether aesthetic considerations are necessary should be taken into account.
If the required axial force for tightening the point is large and there is sufficient external tightening space, it is recommended to use external hexagonal bolts.
If there are space limitations in the tightening position, or if there is a need to make it aesthetically pleasing with a countersunk head, and the axial force required for the tightening point is not large, an internal hexagonal bolt can be selected.
In summary, external hexagonal bolts have become the preferred fasteners in many application scenarios due to their diverse specifications, excellent mechanical performance, and cost-effectiveness.
