Hex Socket Head Cap Screw DIN 912 Alloy Steel 8.8 and 12.9 or Stainless Steel 304 and 316 Fastener for Machinery and Mold Assembly

Hex Socket Head Cap Screws use a cylindrical head with an internal hexagonal drive. The recessed drive allows tightening with an Allen key or hex bit, making this screw type suitable for assembly positions where external wrench access is limited or where a compact head profile is preferred.

Manufactured to DIN 912, these screws are widely used in machinery, molds, fixtures, fabricated metal parts, and equipment assemblies. The cylindrical head and socket drive make them a practical option for repeated assembly, maintenance, component replacement, and precision fastening work.

Alloy steel Grade 8.8 and Grade 12.9 options are available for applications requiring specified strength grades. Stainless steel 304 and 316 options are available for buyers who need stainless material options for their assembly requirements.

Product Specifications

Internal Hex Drive for Compact Assemblies

The internal hex socket design is one of the main reasons buyers select DIN 912 cap screws. Instead of requiring side access for a spanner, the screw can be tightened from the top of the head using a matching hex key or bit.

This makes DIN 912 screws suitable for machinery parts, mold inserts, fixtures, enclosed assemblies, and equipment locations with limited surrounding space. The cylindrical head also provides a neat and consistent appearance for equipment and mechanical assemblies.

Alloy Steel and Stainless Steel Options

Different applications may require different screw materials or grades. This DIN 912 Hex Socket Head Cap Screw range provides both alloy steel and stainless steel options.

Alloy Steel Grade 8.8 is available for applications requiring a defined alloy steel fastening grade.

Alloy Steel Grade 12.9 is available for machinery, mold, and equipment assemblies that specify a higher strength-grade option.

Stainless Steel 304 is available for buyers requiring a commonly used stainless steel option.

Stainless Steel 316 is available for applications requiring a stainless steel material option based on the project or assembly requirement.

When requesting a quotation, buyers should state the required material and grade clearly to ensure the screw matches the product drawing or assembly specification.
