Inference & likely role of “Metal Washer‑p” in TC501 context

Given that TC501 (and variants such as TC501CVK) is a TOTO toilet seat & cover (with soft‑close hinges)

bechennai.com a “Metal Washer‑p” suffix is likely a small part associated with the hinge or mounting hardware. The “L4” variant suggests that in the “L‑series / variant 4” of the seat/cover, that particular metal washer part had a specific dimension or version.

So the “metal washer” is likely:

• A flat or shaped metal washer used under a hinge bolt, pivot, or mounting screw
• 
  
• A washer that helps in spacing, stabilizing, or distributing load for the hinge assembly
• 
  
• Possibly a washer that mates the seat hinge to the bowl, or under the hinge pivot (to reduce friction or wear)

Because it’s a “metal washer”, it is likely made of stainless steel (or corrosion‑resistant metal) to match the hinge hardware longevity.

What you need to identify the exact “Metal Washer‑p”

To source or replicate this washer, you should get:

1. Outer diameter (OD) — the outer dimension of the washer
2. 
   
3. Inner diameter (ID) / bore — the hole diameter that fits the bolt / pivot
4. 
   
5. Thickness — how thick the washer is
6. 
   
7. Washer type / shape — flat washer, countersunk, beveled, cupped, wave washer, etc.
8. 
   
9. Material / finish — stainless steel (likely), plating, corrosion resistance
10. 
    
11. Any special features — e.g. lip, flange, shoulder, groove, chamfer
12. 
    
13. Position in assembly — which hinge / mounting screw the washer goes with

Also, look for markings or part numbers on the washer or nearby hinge parts — sometimes TOTO embosses tiny codes on metal parts (though often small).

What you can do to get the exact part or its drawing

1. Remove / inspect the hinge hardware
2. Disassemble one hinge on the seat, remove the washer in question, and take precise measurements with calipers.
3. Look for internal part diagrams / exploded views

• Ask TOTO support or your regional TOTO parts dealer for the service parts catalog for TC501 seats.
• 
  
• That might include the washer (often in the hinge subassembly) with its part number and engineering drawing.

1. Show the part to a TOTO spare parts dealer
2. Bring the seat hinge and the actual washer to a TOTO spares store. They can often match by sight, especially if they have the seat model (TC501) and variant (L4) in their parts index.
3. Ask TOTO support with photos & measurements
4. Send them: a close-up photo of the hinge assembly showing the washer in place, and the measurements (OD, ID, thickness). Ask: “In TC501‑L4, what is the part number and spec of the metal washer used under the hinge?”
5. Compare with the standard TC501CVK drawings
6. The TC501CVK model has downloadable 2D / 3D data in TOTO’s Europe site.
7. If the “L4” variant is similar, you might find the washer in the TC501CVK 2D / 3D drawings, then check whether “L4” alters its dimensions.
