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.
Fabory offers a wide range of countersunk head socket cap screws, available in various sizes, materials, and surface treatments. These include options like steel, stainless steel, and alloy steel with treatments such as plain, zinc-plated, and zinc flake Cr6+ free. The screws are available in different diameters (e.g., M2 to M24) and lengths (e.g., 4 mm to 200 mm). They conform to standards like ISO 10642, DIN 7991, and ASME B18.3 and come from brands like Fabory and Lubrinox.
