What Are the Common Types And Suitable Scenarios of Set Screws in Door Handles

There are several different types of set screws commonly used in door handles. The specific type of set screw used may vary depending on the design of the door handle and the manufacturer’s preferences. Here are a few commonly used types:

Cup Point Set Screws

A cup point set screw has a concave or cup-shaped indentation on the end, which creates a firm grip for providing good resistance. It is commonly suitable for spherical door handles, providing a good force-bearing area and preventing the handle from rotating.

Flat Point Set Screws

The flat point set screw has a flat end surface without any indentation, providing a larger surface area of contact when tightened against on a shaft or spindle, in order to distribute the pressure evenly. They are mostly used for lever handles, flush with the handle surface, not affecting aesthetics.

Oval Point Set Screws

An oval point set screw has an oval-shaped indentation on the end to provide a concentrated contact area, and create a secure grip, when tightened against a shaft or spindle. It is often suitable for some retro-style door handles where the set screw needs to be aligned with a groove or indentation on the shaft for added stability.

Cone Point Set Screw

The cone point set screw has a pointed cone-shaped end for providing excellent grip and can penetrate into the shaft or spindle, and ensuring a strong connection, so that they can be embedded into pre-drilled holes in the door handle in order to conceal and fix, and they are commonly used for high-end custom doors.

Knurled Cup Point Set Screw

A knurled cup point set screw has a cup-shaped indentation on the end with a textured knurled surface, for providing enhanced grip and resistance to loosening, even in applications with vibrations or movement. This type of set screw is often used in door handles that require a humid environment or a more secure fastening in challenging conditions.

It’s important to note that the exact set screw used in a door handle might depend on what the manufacturer says, the overall design of the handle, and even the material of the shaft , or spindle that’s being fastened. In other words, the style can shift a bit, not just one universal solution. It’s always a good idea to check the set screw manufacturer’s guidelines or their specifications so you get the right type and size for that particular door handle.

What are the Sizes of the Set Screws for Door Handle

The sizes of the set screw used in a door handle can vary depending on the specific door handle design, manufacturer specifications, and the type of set screw used. Generally, the size of the set screw is determined by its diameter and length. The most common specifications reference for door handles are:

Door Handle Type	Common Screw Diameter	Common Screw Length
Spherical Handle	M3-M4	8mm-12mm
Lever Handle	M4-M5	10mm-15mm
Smart Lock Handle	M5-M6	12mm-18mm

It’s important to know that the set screw size can change quite a bit from one door handle model to another, and even between different manufacturers. So when you’re installing, or replacing, those set screws on a door handle, it’s smart to check the manufacturer’s own instructions, or the specs that came with the handle. That way you’ll make sure you use the right size, because otherwise it can get finicky.
