Yes. As a custom fasteners manufacturer with over twenty years of experience, At HETAI, custom fasteners can be manufactured according to applicable DIN (Deutsches Institut für Normung) standards while accommodating customer-specific designs, dimensions, materials, and performance requirements.

Although custom fasteners often feature non-standard designs, certain specifications can still follow established DIN standards. These may include dimensions, thread types, tolerances, mechanical properties, and material requirements.

For example, custom bolts can incorporate DIN-standard thread specifications while featuring a specially designed head shape or non-standard length. Similarly, custom nuts, screws, studs, pins, and other precision hardware components can be manufactured with selected features that comply with relevant DIN requirements.

Common DIN standards used in the fastener industry include:

• DIN 933: Hexagon head bolts with full thread.
• DIN 931: Hexagon head bolts with partial thread.
• DIN 934: Hexagon regular nuts.
• DIN 912: Hexagon socket head cap screws.
• DIN 985: Prevailing torque type hexagon nuts with a non-metallic insert.
• DIN 7985: Pan head screws with Phillips cross recess.
• DIN 125: Plain washers.

At HETAI, we review customer drawings and technical specifications to determine which DIN requirements are applicable to each custom fastener. Depending on the product, we can control critical dimensions, thread accuracy, material selection, mechanical properties, and surface treatments according to the agreed technical requirements.

To manufacture custom fasteners according to DIN standards, customers are encouraged to provide 2D engineering drawings, 3D CAD models, material specifications, required tolerances, surface treatment requirements, and order quantities.

Established in 2001, HETAI specializes in manufacturing custom bolts, screws, nuts, and precision hardware components. We combine flexible custom manufacturing capabilities with applicable international standards, helping customers develop non-standard fasteners that meet their specific engineering and application requirements.
