Overview

The DIN 25201 Double Tab Lock Washer is a precision-engineered retaining component designed to deliver superior vibration resistance in critical bolted connections. This washer provides a reliable, mechanical locking action to prevent fastener loosening under dynamic loads, shock, and vibration, ensuring the long-term integrity of assemblies. Manufactured from robust carbon steel and protected with a high-performance Dacromet finish, it offers excellent durability and corrosion resistance for use in challenging industrial environments. Supplied in a bulk quantity of 1000 pieces, it is ideal for high-volume production lines and maintenance inventories.

Key Features

Engineered to DIN 25201 standard for assured dimensional consistency and performance. Double-tab design creates a powerful spring and locking action against both the bolt head/nut and the workpiece. Dacromet finish provides exceptional corrosion resistance without hydrogen embrittlement risks. Positive mechanical lock eliminates reliance on friction alone, preventing rotational loosening. Bulk packaging of 1000 units supports efficient, high-volume assembly operations. Reusable design allows for disassembly and reassembly without significant loss of locking performance.

Frequently Asked Questions

What are the key specifications for this lock washer, and how does the M12 thread size relate to the bore diameter?
This is a DIN 25201 standard double tab lock washer made from carbon steel with a Dacromet finish for corrosion resistance. It has a 0.472 inch bore diameter, a thickness of 0.063 inches, and is designed for use with M12 fasteners, which have a nominal thread diameter of approximately 0.472 inches.
What are the typical applications for this type of lock washer?
This washer is designed for high-vibration environments where a secure, non-loosening lock is critical, such as in heavy machinery, automotive assemblies, or structural steelwork. The double tab design bites into both the nut and the bearing surface to prevent rotation and back-off.
What is the packaging quantity, and are smaller quantities available?
This item is packaged and sold in bulk quantities of 1000 pieces per box. For smaller quantity requirements, please contact our sales team to discuss potential alternative packaging or sourcing options.
