Key features

• 
  Drive type: Hexagon socket head (Allen) for a flush, low-profile fit that stays out of the way during assembly.
• 
  Material and finish: Carbon steel core with black zinc plating for decent strength and a corrosion-resistant, matte-black appearance.
• 
  Three-piece set: Three matching screws designed to tackle common mounting tasks with a consistent finish.
• 
  Condition: Pre-owned, inspected for functional integrity; cosmetic wear may be present, which is typical for used hardware.

Why choose this three-screw set?

If you’re assembling furniture, mounting brackets, or securing components where a restrained screw head and clean aesthetic matter, this hex socket head set delivers. The black zinc coating helps resist light corrosion in indoor environments, while the carbon steel delivers reliable bite and holding power for everyday applications.

Use cases and scenarios

• Furniture assembly and repair where a flush drive is preferred to avoid snagging on fabric or upholstery.
• Mounting brackets or hardware to wooden or composite panels in DIY projects.
• Repair work where replacement fasteners are needed to maintain a consistent finish with existing hardware.

Installation tips

• Choose a hex key that matches the socket size for a secure, torque-controlled drive.
• Align holes or threaded inserts before tightening to prevent cross-threading.
• Drive until the head sits just flush with the surface to maintain a neat appearance and reduce interference with moving parts.

Care and considerations

• Store in a dry, cool place to slow any potential rusting of the used coating.
• Before critical-load use, inspect threads for signs of wear or deformation and replace if necessary.
• As a used item, expect minor cosmetic imperfections that do not affect functional performance.
