Socket Head Cap Screws

Socket head cap screws are cylindrical fasteners with a hexagonal recess in the head, designed to be driven using a hex key or Allen wrench. They are commonly used in applications requiring a clean, flush finish and high-strength fastening. These screws are ideal for assembly in tight or hard-to-reach spaces due to their compact head design.

Socket head cap screws are typically made from stainless steel, alloy steel, carbon steel, or brass. For corrosion resistance, stainless steel is preferred, while alloy steel is used for high-strength applications. Some may also be coated or plated, such as zinc or black oxide, for additional protection or aesthetic purposes.

These screws offer several benefits, including a high-strength design, compact head for space-saving, and easy installation in tight areas. The hexagonal recess ensures better torque application without damaging the screw head. They also provide a neat appearance, making them ideal for machine assembly and aesthetic projects.

In many cases, socket head cap screws can be reused, especially if they remain undamaged during installation or removal. However, in critical applications or when subjected to extreme stress or fatigue, it is recommended to replace them to maintain safety and integrity.
