Introduction

The hexagon socket head cap screw, compliant with DIN 912, UNI 5931, and ISO 4762 standards, is an essential component in many industrial and mechanical applications. With an M30x80 thread and a 12.9 property class, this screw is designed to ensure high performance and long life even under heavy loads. We'll explore the screw's technical specifications and features in detail, offering advice on how to use and maintain it, especially if purchased used.

Construction and Components

The DIN 912 hexagon socket head cap screw is made from the following components and materials:

• Screw Body : The screw body is cylindrical and designed for easy and secure insertion into threaded holes. The thread is M30x80, with a diameter of 30 mm and a length of 80 mm.
• Cylindrical Head : The cylindrical head with a hex socket allows the use of Allen tools for precise tightening. The cylindrical shape allows for a uniform fit in tight spaces.
• Material : The screw is made of high-strength steel, conforming to strength class 12.9, which ensures superior tensile strength and deformation resistance.

The main dimensions of the screw are a diameter of 30 mm and a length of 80 mm. Class 12.9 indicates a tensile strength of at least 1,200 MPa and a hardness of 39-43 HRC.

Technical Characteristics

• Thread : M30x80, which offers a robust and secure connection for applications requiring high load capacity.
• Resistance Class : 12.9, ensuring high mechanical properties and long life.
• Reference Standards : Complies with DIN 912, UNI 5931 and ISO 4762, which ensure compatibility and quality according to international standards.

Use and Procedure

To use the DIN 912 hexagon socket head cap screw , follow these steps:

1. Preparation : Make sure the threaded hole where the screw will be inserted is clean and free of debris.
2. Insertion : Place the screw into the threaded hole.
3. Tighten : Use the correct size Allen key to tighten. The cylindrical head allows for precise, slip-free tightening.
4. Check : Check that the screw is securely fastened and that there are no signs of loosening.

Matching accessories

Accessories compatible with the socket head cap screw include:

• Allen Keys : For precise and secure tightening of the screw.
