Product Information

Full details

The Sealey FWC1430 Form C flat washer is an essential component for engineers, mechanics, and DIY enthusiasts who require secure load distribution in heavy-duty fastening applications. Designed with a wider diameter than standard Form A or B washers, this M14 component increases the clamping surface area, effectively preventing damage to the bolted material. While it offers superior stability for structural connections, users should note that the increased diameter may interfere with tight clearances in recessed mounting holes.

Extended Product Information

FAQs

What is the difference between Form A, B, and C washers?

Form C washers are designed with a larger outside diameter than standard Form A or B, providing a wider clamping area for better load distribution.

Are these washers suitable for outdoor use?

These are finished in silver; while durable, if using in exposed outdoor conditions, ensure they are kept clean or coated with a corrosion inhibitor.

How many washers are included in the pack?

Each pack contains 50 units.

Can these be used with non-M14 bolts?

No, they are specifically sized for M14 hardware to ensure a proper fit and load distribution.

What does BS 4320 mean?

It is the British Standard for metal washers, ensuring the product meets specific dimensions and quality requirements for industrial and mechanical use.

Troubleshooting

Washer does not sit flush against the mounting surface.

Check the mounting surface for debris or burrs and ensure the bolt hole is not causing an obstruction.

Washer is too large for the intended space.

Verify if a standard Form A or B washer is required, as the Form C has a intentionally larger outer diameter.

Pros and Cons

Pros

  • Wider diameter allows for superior load distribution
  • Manufactured to official BS 4320 standards
  • Comes in a convenient, resealable storage bag
  • Ideal for heavy-duty mechanical applications

Cons

  • Larger diameter may not fit in countersunk or tight clearance holes
  • Limited to M14 bolt sizes
  • 50-pack size may be more than needed for minor home repairs

Setup, Compatibility & Care

  • Compatibility: Designed specifically for M14 bolts or threaded rods. Ensure the hole diameter of the material is not significantly larger than the bolt to prevent the washer from slipping.
  • Installation: Place the washer onto the bolt shank before tightening the nut. Ensure the wider face is against the substrate for optimal load bearing.
  • Care: Keep the washers in the provided resealable bag when not in use to prevent oxidation and to maintain a clean surface finish. If used in high-moisture environments, consider applying a light coating of machine oil to prevent surface corrosion.
