Hex Socket Flathead Carbon Steel Bolts

When fastening space is limited, a low-profile bolt head can make assembly cleaner and more practical. Our Hex Socket Flathead Carbon Steel Bolts are designed for applications requiring a flat or countersunk head, internal hex drive, and carbon steel construction. They are suitable for machinery, equipment assembly, fixtures, OEM production, and industrial maintenance worldwide.

As Alisa, Export Director at Hanyang Machinery with 10 years of industrial equipment export experience, I work with global distributors, OEM buyers, engineering contractors, and MRO procurement teams. We support standard and drawing-based bolt production, helping buyers confirm dimensions, thread specifications, material grade, strength requirements, and surface treatment before production.

Product Parameters

Technical Note: Exact head angle, diameter, length, thread standard, strength grade, surface treatment, and dimensional tolerances should be confirmed against the applicable drawing or purchase specification.

Key Features

Flathead Design

The flathead configuration is suitable for applications where the bolt head needs to sit flush or close to flush with the assembled surface after installation into a compatible countersunk hole.

Internal Hex Drive

The hex socket provides a compact drive interface and is useful where side access for conventional wrench-based fasteners is restricted.

Carbon Steel Construction

Carbon steel provides a practical balance of strength, machinability, and cost for many industrial fastening applications. The appropriate grade should be selected according to the required mechanical performance and service environment.

Clean Assembly Appearance

The recessed head design can reduce protrusion above the working surface, making it useful for machinery panels, fixtures, brackets, and equipment components where clearance is important.

Typical Applications

Industrial Machinery
Used for machinery components where a flush fastening point and internal hex drive are required.

OEM Equipment Assembly
Suitable for equipment manufacturers specifying repeatable bolt dimensions for production assemblies.

Fixtures and Jigs
The flathead design can help maintain a relatively smooth fixture surface and reduce interference with adjacent components.

Metal Fabrication
Applicable to compatible fabricated assemblies requiring countersunk fastening.

Equipment Maintenance
Suitable for MRO buyers and distributors sourcing replacement bolts according to existing dimensions and thread specifications.

General Industrial Assembly
Can be used in compatible applications where carbon steel strength and a compact fastening configuration meet the design requirements.
