TOTO THP5178 – Frequently Asked Questions
1) What exactly is TOTO part THP5178?
THP5178 is a TOTO faucet set screw, the small fastener that secures a handle to the valve stem. It is a replacement fastener only, not a handle assembly or a cartridge.
2) Do I get a new faucet handle if I order THP5178?
No. THP5178 is the set screw alone. If the handle itself is cracked, stripped at the broach, or missing, you need the handle part number for your faucet model, not this fastener.
3) My TOTO faucet handle spins without turning the water on, do I need this screw?
That is the usual symptom of a loose or missing handle set screw, and THP5178 is the TOTO faucet set screw sold for that repair. If the screw is present and tight and the handle still spins, the fault is upstream at the stem or cartridge instead.
4) Is THP5178 a plumbing part or a shower/tub trim part?
It is a plumbing fastener for a faucet. TOTO lists the application as faucet, so order against your faucet model rather than assuming it carries over to shower or tub trim hardware.
5) How do I order the right TOTO faucet set screw for a maintenance stock room?
Order by the TOTO part number. THP5178 is a single, fixed part with no size, finish, or handing choice to specify, so a property manager or MRO buyer stocking spares just needs the quantity and the confirmation that the faucet it serves is a TOTO model calling for THP5178.
