Washer PD 12 GMT PD 12_GMT

Steel washers for metric screws – durability and reliability

The PD 12 GMT washer is a fastening element made of steel, designed for use with metric screws with a diameter of 12 mm. Its construction ensures even load distribution and prevents damage to threads, which translates to a longer service life of connections. GEOMET surface treatment increases corrosion resistance, which is particularly important in installations exposed to moisture or atmospheric factors.

Construction and application

The washer is characterized by an outer diameter of 24 mm and a thickness of 1.2 mm, and its inner hole has a diameter of 13 mm. This construction guarantees stable positioning of the washer under the screw head and effectively protects against loosening of the connection. It finds application in a wide range of electrical, mechanical and construction installations – wherever a solid and durable structure is required.

Important features and benefits

• Corrosion resistance: The GEOMET coating provides effective protection against environmental influences, which extends the life of the connection and minimizes the risk of failure.
• Even load distribution: Prevents damage to screw and fastened element threads, increasing installation safety.
• Versatility: Intended for metric screws M12, the washer is compatible with a wide range of fastening elements.
• Durability: Made of steel, it provides high mechanical strength and resistance to wear.
• Application in fire protection systems: Detailed information on the use in fire-resistant systems can be found in the Fire Resistant Systems catalog (orange catalog). This is important for installers carrying out projects requiring compliance with strict fire safety standards.
