Fitting a Grub Screw

Many of our door handles come with a grub screw which is located in the neck of the door handle. It is usually tightened by an allen key or small screw driver. If the grub screw is not correctly positioned in the groove of the spindle or on the tapered edge (Ceramic Door Knobs) then this can cause issues when using the door knob. The grub screw is very important and is what locates and secures the door knobs to the spindle, thus engaging the latch when turned.

 

 

 

The majority of our door knobs are very simple in their design and just include the pair of handles and backplates, two grub screws and fixing screws for the backplates. Many of the designs are based on antique originals and our suppliers have kept the design virtually identical. The latch in the door is what does all the work and needs to be heavily sprung to allow the door knobs to return to their original position once turned.

The grub screw is what attaches the door knobs to the spindle which when turned engages the latch.

The spindle has a groove that runs down at least two sides of the spindle and some of our spindles have location holes where the grub screw needs to sit. If the grub screw is not correctly located then it will cause the handles to spin on the spindle which in turn damages both the spindle and the grub screw and mean they would need to be replaced (and in some cases new door knobs depending on the damage caused.)

From time to time the grub screw may work loose and simply needs to be re tightened with a screw driver or with the allen key insuring it is located in the groove or location holes.

Once you have put the spindle through the door latch you can then tighten your door knobs up to the door. Be sure not to over tighten as this can cause you door knobs to pinch when used. Once you are happy with their location and you have attached the back plate to the door you can then tighten the grub screw. The grub screw MUST be tightened into the groove of the spindle or location holes otherwise it will just work loose and cause the handles to turn but not engage the latch.

 

Top Tip: Some of our backplates (Beehive & Bloxwich) have a hole in the neck of the backplate which needs to line up with the hole in the neck of the handle for the grub screw to be located in. Make sure you have lined this hole up with the neck of the handle and the groove in the spindle before fixing the backplate to the door, otherwise you will be unable to insert the grub screw.
