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.

Our Upvc casement window handles are split into three categories, Cockspur Handles, Espage Handles and Spaded Handles. These are the most common type of Upvc window repair handles you will come across on properties today.

We also take no compromise on handling and spindle length, with left, right and non-handed products on offer from 30-55mm to cater for every demand. On top of this, outer screw centres can be desired between 25-62mm along with step heights.

The thing with step heights is that various measurements have been used over the years, with some being more common than others. For example, 21mm is more common for a UPVC window and 9mm is commonly used in aluminium windows.

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. My grub screws keep falling out, how can I fix this problem?” Is a question we are sometimes asked. Let's take a look at what causes this and how to resolve this problem, as well as asking what type of grub screw is best to use, and actually why it is that we use grub screws.
