Internal hexagon head screw, commonly referred to as internal hexagon screw or internal hexagon bolt, is a type of fastener with an internal hexagon head. This design allows the use of tools such as hex wrenches, hex keys, or hex wrench kits for tightening or loosening operations, without easily damaging the head due to external forces like straight or cross screws.

characteristic

High strength: Internal hexagon head screws typically have high tensile and shear strength, making them suitable for applications that require bearing large loads.

Wear resistance: Due to the design of the hexagonal head, the screw head is not easily damaged by external forces, which improves its service life.

Easy to install and disassemble: Special tools can be used to easily tighten or loosen screws, improving work efficiency.

Good anti loosening effect: Inner hexagon screws combined with locking washers or coatings and other anti loosening measures can effectively prevent loosening.

texture of material

There are various materials for hex head screws, including carbon steel, stainless steel, alloy steel, etc. Among them, carbon steel screws have the characteristics of low cost and moderate strength; Stainless steel screws have the characteristics of corrosion resistance and aesthetics, and are suitable for humid or corrosive environments; Alloy steel screws have higher strength and hardness, making them suitable for applications that require extreme loads.

Specifications and dimensions

The specifications and dimensions of hex head screws are usually determined based on their diameter (also known as nominal diameter), length, thread type (such as coarse or fine thread), and head size. These specifications and sizes can be customized according to different application requirements.
