Toto spares, Toto parts, Toto spare parts, Spare code no : BOVITINOX - ssbolts & nuts up. What’s known: TOTO H34608007 – Stainless Steel Bolts & Nut

• Brand: TOTO.
• 
  
• Part number: H34608007.
• 
  
• It is labelled as “Stainless Steel Bolts And Nut”.
• 
  
• The item is reportedly discontinued.

What I couldn’t find:

• Exact dimensions (bolt diameter, thread size, length) are not published in the sources I saw.
• 
  
• What specific TOTO models it fits (toilet tank‑to‑bowl, seat hinges, etc.) is not clearly stated.
• 
  
• No mention of grade of stainless steel (304, 316, etc.) for that specific part.

What “SS bolts & nuts up” likely means in this context

• “SS” = Stainless Steel (inox) bolts & nuts: high corrosion resistance.
• 
  
• “Up” possibly means “upper / seat / top / covering”. Could refer to bolts & nuts used in the seat hinge, or tank mounting, etc.
• 
  
• “Bovitinox” is likely a colloquial or local corruption of “Bolt + Inox (stainless)”.

So, in TOTO toilets, this set is possibly used for either:

1. Seat Seat / Toilet seat hinges — securing the toilet seat & cover.
2. 
   
3. Tank to Bowl bolts — fixing the tank (cistern) onto the bowl.
4. 
   
5. Mounting / base bolts in certain models (especially if the bolt set is designed stainless steel to avoid rust).

What you need to check to replace or confirm compatibility

Since the original part is discontinued or not clearly spec’d, here's a checklist to match a replacement:

ParameterWhat to measure / checkThread DiameterUse a caliper to measure the diameter of the bolt thread. Could be metric (e.g. M6, M8) or imperial.Thread PitchHow fine/coarse the thread is. If you have a thread gauge, that helps; otherwise compare with existing bolt.Bolt LengthFrom bottom of head to end (when tightened) – must account for washers, tank thickness etc.Bolt Head TypeHex, cap, pancake, flat, etc. Some heads are decorative/capped.Nut Type & AccessoriesDo you need wing nuts, hex nuts, rubber washers/gaskets, plastic or metal washers?Bolt Material / GradePreferably SS 304 or SS 316 (316 if exposure to harsh chemicals or salt / coastal).Finish & Corrosion ResistancePolished, passivated, etc., to resist rust / stains.Compatibility with Toilet ModelSome toilets / seats have countersunk holes, or need capped bolts so they don’t protrude.

Possible alternatives

Since the original is discontinued, you might need to source equivalent SS bolt & nut sets. Some universal kits are available (tank‑to‑bowl, seat hinge kits) with SS bolts, washers, rubber seals. These are not always “official TOTO”, but can work if specs match.

Also, local fastener shops in Chennai often carry SS bolts/nuts and can custom match length + thread.
