3. Installation and Usage
Burndy Durium flat washers are designed to distribute the load of a threaded fastener, such as a nut or bolt head, evenly across a larger surface area. This helps to prevent damage to the fastened material and can also reduce the likelihood of the fastener loosening over time due to vibration.
3.1. Proper Selection
Ensure that the washer's inner diameter matches the bolt size. This specific washer is designed for 1/2-inch bolts. Using a washer with an incorrect inner diameter can compromise the integrity of the fastening.
3.2. Installation Steps
- Prepare Surfaces: Ensure that the surfaces where the washer will be placed are clean, dry, and free from debris or burrs.
- Position Washer: Place the flat washer directly under the head of the bolt or under the nut, depending on the application. Typically, flat washers are placed under the rotating element (the nut or the bolt head if the nut is fixed).
- Assemble Fastener: Insert the bolt through the components to be joined, then through the washer, and finally secure with a nut if applicable.
- Tighten: Tighten the fastener to the manufacturer's recommended torque specifications. The washer will help distribute the clamping force.
3.3. Material Compatibility
The silicon bronze construction of this washer makes it particularly suitable for applications where galvanic corrosion with copper components is a concern. Its non-magnetic properties are also beneficial in specific electrical or sensitive environments.
4. Maintenance
Burndy Durium flat washers are designed for durability and require minimal maintenance. However, periodic inspection is recommended, especially in critical applications or harsh environments.
- Visual Inspection: Regularly check installed washers for signs of corrosion, deformation, cracking, or wear.
- Cleaning: If necessary, clean the washers with a mild, non-abrasive cleaner and a soft cloth. Ensure they are completely dry before re-installation or storage.
- Replacement: Replace any washer that shows signs of damage or excessive wear to maintain the integrity of the fastening.
5. Troubleshooting
While flat washers are simple components, issues can arise from improper selection or installation.
- Fastener Loosening: If fasteners are loosening, ensure the correct torque was applied and consider if a locking washer (e.g., split lock washer, external tooth lock washer) is also required in addition to the flat washer for vibration resistance.
- Material Damage: If the material being fastened is showing signs of crushing or deformation, verify that the flat washer's outside diameter is sufficient to distribute the load effectively.
- Corrosion: Although Durium washers are designed to resist galvanic corrosion with copper, ensure that the surrounding environment and other fastener components are compatible with silicon bronze to prevent other forms of corrosion.
- Incorrect Fit: If the washer does not sit flush or the bolt passes through too loosely, verify that the correct washer size (inner and outer diameter) has been selected for the specific bolt and application.
