Our socket head bolts are manufactured with the utmost care, with both size and material selection fully matched to your application. The compact head design makes these bolts ideally suited to applications with limited installation space or where access from one side is essential. The internal hexagon ensures controlled assembly with minimal chance of damaging the fastener or workpiece - even with repeated disassembly.

 

Custom applications

Our inner hex bolts find their way into applications where performance, material selection and reliability are key, such as:

• Assembly of high-performance machines and mechatronics
• Assembly of vehicles, drive systems and precision equipment
• Structures in chemical or maritime environments
• Applications with requirements for heat resistance, magnetism or chemical inertness

 

Technical specifications

• Material: From high-grade steel to exotic alloys such as Inconel®, Duplex, Monel® or titanium
• Dimensions: Delivery according to drawing, specification or by arrangement
• Finish: Available with various surface treatments, including PTFE, zinc-nickel, black oxidized or WN-1 coating
  • WN-1 represents a zinc-nickel finish in accordance with DIN EN ISO 4042:2018-11, type ZnNi5/Fn/T2 with a controlled coefficient of friction of μ = 0.12-0.18
  • This finish is widely used in defense and aerospace applications, where corrosion protection, electrical conductivity and assembly control under tight tolerances are required
• Standards: In accordance with DIN, ISO or customer-specific standards
• Documentation: Optional with material certificates (EN 10204 3.1 or 3.2), including full traceability for defense and government projects
