Always place the washer directly under the head of the bolt or the nut, depending on the direction of the applied load. For critical applications, use washers on both ends (bolt head and nut) to ensure uniform stress distribution.

3. Avoid Over-Tightening the Bolt

While torque is essential for joint strength, over-tightening can deform the washer and reduce its effectiveness. Use a calibrated torque wrench and follow recommended torque values for M10 fasteners in your application.

4. Check for Flatness Before Use

Inspect each washer before installation. A warped or uneven washer may cause improper clamping force and damage the joint. Replace any washer that is bent, scratched, or visibly deformed.

5. Pair With Compatible Materials

For optimal results, use M10 SS202 Plain Washers with stainless steel bolts of compatible grades. Mismatched materials may lead to galvanic corrosion or fastener failure over time.

6. Apply Protective Coatings When Needed

In environments with elevated moisture, chemicals, or temperature variation, consider using protective coatings (such as anti-seize lubricants or zinc sprays) to further safeguard both the washer and the joint.

7. Use in Conjunction with Locking Elements (If Required)

In high-vibration settings, combine M10 SS202 Plain Washers with locking washers, thread lockers, or lock nuts to ensure enhanced vibration resistance and fastening security.

Maintenance Guidelines for M10 SS202 Plain Washers

Although M10 SS202 Plain Washers are known for their durability and low upkeep, proper maintenance ensures they continue to perform efficiently over extended periods. Here’s how to maintain them effectively:

1. Proper Storage

Store the washers in a dry, sealed container or cabinet to prevent exposure to moisture or corrosive substances. Avoid leaving them in open or humid environments, especially near chemicals or oils.

2. Regular Inspection Intervals

Establish a schedule to inspect fastened assemblies that use M10 SS202 Plain Washers. Focus on critical equipment every 3 to 6 months or more frequently in high-load or high-vibration environments.
