TOTO TH559EDV341 – Frequently Asked Questions
1) What is TOTO part TH559EDV341?
TH559EDV341 is a TOTO double SEMS screw set in M3 size, sold as a replacement fastener set for a wall frame. SEMS screws come with the washer pre-assembled and captive under the head, so the washer cannot be dropped or lost during installation.
2) Is TOTO TH559EDV341 a complete wall frame or just the screws?
Just the fasteners. TH559EDV341 is the M3 double SEMS screw set only, a service part for a TOTO wall frame. If you need the carrier or frame itself, order that separately; this part number gets you the screws and nothing else.
3) What thread size are the TOTO TH559EDV341 screws?
They are M3, the metric thread size called out in the part description. If the screw you are replacing measures a 3 mm major diameter on the threads, this is the matching set. Anything larger, such as M4 or M5, is a different TOTO service part.
4) I lost the screws off my TOTO wall frame during a remodel. Will this set replace them?
It will, provided the originals were the M3 double SEMS type used on that frame. TOTO sells these as a service part specifically so a property manager or plumber can restore the original fastener rather than substitute a hardware store screw. Match the part number TH559EDV341 against your TOTO parts diagram before ordering, since TOTO uses different screw sets across its wall frame and carrier models.
5) Can I just use a generic M3 machine screw instead of the TOTO set?
You can thread a generic M3 into the same hole, but you lose what makes this a SEMS screw: the washer is captive under the head, so it stays with the fastener in a blind or overhead wall frame location where a loose washer disappears into the cavity. Head style, length, and finish on the TOTO set are matched to the frame as built, which a generic screw will not guarantee.
6) How many screws come in the TOTO TH559EDV341 set?
It is sold as a set under a single TOTO part number, TH559EDV341, rather than as loose individual screws. Order one part number per frame you are servicing. If you are standardizing spares across a building with multiple TOTO wall frames, order one set per fixture position you want covered.
7) Are there different finish or size options for TOTO TH559EDV341?
No options to choose. The M3 double SEMS screw set ships as one configuration under TH559EDV341, so there is nothing to specify on the order beyond quantity.
