Setup and Installation
Fender washers are used to distribute the load of a threaded fastener, such as a screw or nut, over a larger area. This helps prevent damage to the material being fastened and provides a more secure connection.
- Select the Correct Size: Ensure the washer's inner diameter matches the diameter of the bolt or screw being used. The outer diameter should be appropriate for the application to provide sufficient load distribution without interfering with other components.
- Placement: Place the fender washer directly under the head of the bolt or screw, or under the nut, depending on the application. The washer should be flush against the material surface.
- Tightening: Tighten the fastener according to the manufacturer's specifications for the bolt/screw and the material being joined. Avoid over-tightening, which can deform the washer or damage the material.

Operating Principles
The primary function of this fender washer is to increase the bearing surface under a fastener. This is particularly useful in applications involving soft materials, thin sheet metal, or oversized holes, where a standard washer might pull through or cause localized stress.
By distributing the pressure over a wider area, the washer:
- Reduces the risk of material deformation or damage.
- Enhances the stability and longevity of the fastened joint.
- Provides a clean, finished appearance by covering larger holes or imperfections.
Maintenance
Hillman 830602 fender washers are made from stainless steel, offering inherent resistance to corrosion. Minimal maintenance is required for these components.
- Inspection: Periodically inspect fastened joints for any signs of loosening or wear.
- Cleaning: If exposed to harsh environments or contaminants, clean the washers with a mild detergent and water, then rinse thoroughly and dry to maintain their finish and corrosion resistance.
- Storage: Store unused washers in a dry environment to prevent potential surface discoloration, although stainless steel is highly resistant to rust.
Troubleshooting
While fender washers are simple components, issues can arise from improper selection or installation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Washer pulls through material | Washer outer diameter is too small for the application, or material is too soft. | Use a washer with a larger outer diameter or reinforce the material. |
| Fastener loosens over time | Insufficient tightening, or vibration in the application. | Ensure proper torque during installation. Consider using a lock washer in conjunction with the fender washer for high-vibration applications. |
| Washer deforms during tightening | Over-tightening of the fastener. | Tighten fasteners to recommended specifications. |
