Catch screw ZT-SZM4B – how to choose the right one
ZT-SZM4B is a catch screw in zinc-plated steel from the SZM series. Sold singly, it serves to complete an installation or to make up shortages during a repair.
The only thing that distinguishes it from ZT-SZM5B is the ending of the designation, which the manufacturer does not expand on in the description. The choice therefore cannot be made from the data sheet alone – the starting point is the fitting the screw is to go into.
Items like this go missing faster than they wear out. A single piece that dropped out during removal can hold up a repair for a whole day, which is why service stores keep several of them.
How to match the handle to the door thickness and settle the key system – we explained it in the selection guide for this category.
Where it works
- Completing a set when fitting hardware
- Repair when the original has been mislaid
- Spare parts in mobile servicing

Ask a questionHow does SZM4B differ from SZM5B?
In the designation alone: both items are in zinc-plated steel and have an identical description. The difference is settled by ordering for a specific catch, not by comparing data sheets.
Is a zinc coating enough in a damp room?
In a typical back of house, yes – zinc protects the thread against rust bloom. Under constant steam and pressure washing, stainless fasteners are the safer bet.
