Not Gas related- Shower door knob, anyone help me out?

[alex444]

Evening, been working on my own gaff today, still haven't moved in! Problem being that the shower door has come with no knob and to make matters worse I cannot find the invoice or purchase details (been sitting in the house for months) and its a non branded one!

I measured the hole in the glass and its 7mm Diameter, but when I am looking for them online none of them state the thread size!
Its a bifold door and as such requires a double sided knob.
Anyone know wether they are all 7mm holes?
Or a merchant/ online supplier that states these details?

Thanks, Alex

M7 is not a preferred fastener size. Most fixings for handles (or almost anything else, for that matter) use 4, 5, 6, or 8mm threads.

Older imperial sized 1/4" threads would be about 6.4mm, but it is unlikely you would find them on anything made in the last 25 years.

The hole is probably generously oversized to stop the bolt from chipping the edge of the tempered glass, leading to it shattering.

Most likely the intended fixing was either M4 or M5, with a pair of shouldered plastic washers to protect the edges of the hole in the glass.

You could probably use a pair of cabinet door handles of your choice, which are usually tapped M4, linked with a piece of 4mm studding (or bolt with the head cut off) seated on a pair of fibre washers, with a short offcut of soft plastic tube to line the hole and centre the stud and washers.

Plenty of double sided shower door knobs on google/ebay with thread diameter ie 6mm etc.
