Venetian window handles– these are typically fixed by two bolts, similar to the Espag handle (below). However, in contrast to the Espag handle, Venetian window handles have a low projection from the frame.

The use of an Allen hex drive grub screw against a spindle creates a strong grip, but to make this grip even more secure, we supply most of our door handles with a ‘grooved’ or ‘slotted’ spindle. The Grooved spindle is a special type of spindle which is cut right through at either end, and has a grooved out ‘trough’ surrounding the cut. The purpose of the groove is to accept the grub screw and locates into the groove. The grub screw then wedges into the groove and opens up the spindle, creating a lateral pressure and grips in to the door handle or door knob. This creates an extremely secure fixing.

On occasion, we are asked for advice from a customer whose grub screws seem to unthread themselves, and drop out of their door handles onto the floor. This can result in the door handle coming loose off the door. Why does this occur? Well, the most common cause of this is that the spindles have been installed the wrong way up, so that the grooved or slotted face is facing away from the grub screw. When this occurs, the grub screw cannot bite into the spindle, and will work itself loose over time, eventually dropping out onto the floor. The problem of grub screws falling out is irritating, but can almost always be cured very easily.

Commonly used on Lever-on-Rose handles and some door knobs. A grub screw, also sometimes known as a 'set-screw' in North America and other countries, is actually rather confusingly a type of bolt. This is because it is grooved, so that it may be threaded into a pre-existing threaded hole, rather than driven into a surface, like a traditional screw would be.
