Mortise Cylinder Set Screw

This polished brass set screw secures a mortise cylinder inside a lock body. It is supplied as a single screw per pack and measures approximately two inches in length. The hardware is designed for straightforward installation during lock assembly or maintenance.

Who should use this screw

The screw fits the Marks 91A mortise lock set and most other mortise lock sets on the market. It is not intended for cylindrical or tubular lock bodies that use a different retaining method. Buyers who need a set screw for a non-mortise mechanism should look at something else.

Critical specification

The approximately two-inch length determines whether the screw reaches the cylinder threads through the door thickness and lock body. Verify this dimension against your specific mortise lock before purchasing.

Questions about this item

Does the MKS14 set screw generate any heat or noise during continuous use?

The MKS14 is a passive brass fastener with no moving parts or electrical components, so it produces no heat and makes no sound once installed in the mortise cylinder.

What mortise lock body must already be on the door for this MKS14 screw to function?

The screw is designed for the Marks 91A mortise lock set and fits most other mortise lock sets that accept a standard cylinder set screw of this length.

Will the MKS14 screw work with the original cylinder hardware already fitted in an older mortise lock?

Yes, the approximately two-inch polished brass screw is compatible with the Marks 91A and most mortise lock sets, so it can secure existing cylinders in older installations.
