Hex Socket Cap Screw DIN 912 Allen Bolt

When Wanluo Factory was developing this Hex Socket Cap Screw DIN 912 Allen Bolt, it relied on integrated cold forging and precise thread rolling processes. The overall structure has high precision and strong locking stability. Combined with high-quality stainless steel, it can maintain a precise locking state for a long time under vibration and complex working conditions. It is the core supporting screw for high-end assembly of automated equipment, precision molds, and instruments and devices.

Product features

1. Embedded installation structure, no assembly interference

Our Hex Socket Cap Screw DIN 912 Allen Bolt adopts a cylindrical head embedded design. After locking, no components are exposed, which will not hinder the movement of surrounding accessories or the assembly and fitting of equipment. It perfectly suits precise structures that require flat surfaces, sealed assembly, and sliding fit, significantly improving the overall assembly integrity of the equipment.

2. Internal hexagonal drive design, strong adaptability in narrow spaces

It has a standard hexagonal drive hole built-in, and can be completed with an internal hexagonal wrench without leaving external wrench rotation space. It specifically solves construction problems in compact structures, dense installation points, and narrow cavities. Its assembly adaptability is far superior to conventional external hexagonal bolts.

3. Precise molding process, precise engagement without slippage

It is formed through a one-piece cold forging process, combined with high-precision thread rolling treatment. The tooth shape is full and uniform, with strict tolerance standards. The inner hole has high concentricity and a smooth inner wall. The disassembly process is tightly fitted, and the high torque locking is not prone to cracking, slipping, or thread breakage. It supports repeated debugging disassembly, and the accuracy does not decrease over a long period.

4. Stable material performance, durable and corrosion-resistant

It selects high-purity stainless steel raw materials, giving the product excellent tensile strength and fatigue resistance. It can withstand frequent vibration and mechanical reciprocating operation conditions of equipment, and also has excellent rust and corrosion resistance. It is not afraid of humid and slight corrosion in complex environments. The durability is significantly improved.

5. Base surface fitting design, uniform locking force

The bottom of the screw is flat, and the head is smoothly rounded. It has an extremely high fit with the workpiece's blind hole, and the locking force is uniform without uneven loading. It will not cause local compression deformation, false locking, or loosening problems, ensuring the consistency of locking strength at each assembly point.

Application scenario

1. Precision mold tooling assembly

2. Automated mechanical equipment assembly

3. Precision instruments and electrical equipment

4. High-end mechanical structure modification and maintenance

Structural Advantages & Process Performance

DIN 912 allen bolts adopt one-piece cold forging forming and precision thread rolling process, with full and uniform thread profile and accurate tolerance control. The standard inner hexagonal groove is deeply processed with smooth inner wall and high concentricity, ensuring tight fit with allen wrenches without slipping or tooth breaking during assembly. The rounded head bottom and flat bearing surface can be closely attached to the workpiece countersunk hole, realizing flush hidden installation without protruding protrusions. High-purity stainless steel raw materials endow the screws with excellent tensile resistance, fatigue resistance and corrosion resistance, maintaining long-term stable fastening accuracy in frequent vibration and harsh working environments, and effectively improving the integrity and aesthetics of equipment assembly.
