Introduction

The cylindrical head screw with hexagon socket, 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 strength class of 12.9, this screw is designed to ensure high performance and long life even under high load conditions. We will analyze in detail the technical specifications and characteristics of the screw, offering advice on how to use and maintain it, especially if purchased as used.

Construction and Components

The cylindrical head screw with hexagon socket DIN 912 is made with 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 type, with a diameter of 30 mm and a length of 80 mm.
• Cylindrical Head : The cylindrical head with 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, complying with strength class 12.9, which guarantees 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, offering a robust and secure connection for applications requiring strong load capacity.
• Resistance Class : 12.9, guaranteeing high mechanical properties and long life.
• Reference Standard : Compliant 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 in the threaded hole.
3. Tighten : Use the correct size Allen (hex) wrench to tighten. The cylindrical head allows precise and slip-free tightening.
4. Check : Check that the screw is well tightened and that there are no signs of loosening.

Matching accessories

Accessories compatible with the cap screw include:

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