The Sealey FWC1228 is an essential component for engineers, mechanics, and automotive professionals who require superior clamping force and load distribution for M12 fastenings. These Form C metric washers are engineered for high-performance applications where a wider surface area is necessary to prevent damage to soft materials or to bridge oversized holes, though users should ensure their specific bolt and nut assembly requires the wider 28mm outer diameter before installation.

Form C refers to a specific series of washers defined by BS 4320, characterized by having a larger outer diameter than standard Form A or B washers to provide more bearing surface.
No, these are precision-engineered for M12 bolts. Using them on incorrect sizes will lead to poor load distribution and potential failure.
Each resealable bag contains 100 units.
These are standard professional-grade silver-finished steel washers manufactured to BS 4320 standards.
The outer diameter is 28mm.
The FWC1228 has a wide Form C diameter. If your application has a limited diameter recess, switch to a narrower Form A or B washer.
Verify that the washer is centered correctly on the bolt shank. If it continues to deform, the torque applied may exceed the capacity of the material being fastened.
To ensure optimal performance, ensure the surface being fastened is flat and clean of debris. Place the washer onto the M12 bolt thread, ensuring it sits flush against the surface before applying the nut. These washers are compatible with all standard metric M12 threaded fasteners. For maintenance, keep the washers stored in their original resealable bag to prevent oxidation. If used in extreme outdoor conditions, consider applying a thin layer of anti-seize or a rust-inhibitive spray to the washer surface before final assembly to extend its operational life.
