Countersunk Head Socket Cap Screws from Fabory: High Torque and Flush Finish

Countersunk head socket cap screws are fasteners with a flat top and a conical bearing surface designed to sit flush with or below the material surface. They are tightened with a hex key or Allen wrench, making them ideal for applications requiring a clean finish, such as machinery, automotive, and furniture assembly.

When choosing these screws, consider the material (steel, stainless steel, or alloy steel), diameter and length, surface treatment for corrosion resistance, compliance with international standards (ISO, DIN, ASME), and hex socket compatibility. These factors ensure proper fit and durability in specific applications.

Due to the unfavourable head geometry, these screws have a reduced load ability. Steel fasteners marked with “0” preceding the property class (i.e. 010.9 or A2-070) have a maximum load of 80% of the tensile strength. As such, the pre-load and application should be considered before use.
