Quick Answer
You only need alternative length M4 screws if your cabinet door or drawer front is thicker or thinner than the standard 25mm screws supplied with your hardware. Choose a screw about 5mm longer than the door thickness.
Why Standard Screws Might Not Fit
Every Plank Hardware handle and knob comes with standard 25mm screws that work with most cabinet doors and drawer fronts. But if your door is thicker (e.g., 30mm) or thinner (e.g., 15mm), those screws will either stick out or not reach. That's where alternative length screws come in.
The key is to match the screw length to the thickness of your door or drawer front. A good rule of thumb is to pick a screw about 5mm longer than the material thickness. For example, a 30mm door needs a 35mm screw.
What Makes M4 Screws Different
M4 refers to the thread diameter (4mm) and pitch of the machine screw. These are metric machine screws, not wood screws. They are designed to thread into a threaded insert or a tapped hole in your hardware, not directly into wood.
The solid brass construction gives them a corrosion-resistant finish that matches the look of your hardware. They are sold in packs of 10, so you have spares or enough for multiple handles.
Frequently Asked Questions About M4 Alternative Screws
When do I need alternative length M4 screws?
Only when your cabinet door or drawer front is thicker or thinner than the standard 25mm screws supplied with your handle or knob. If the standard screws fit, you don't need this pack. Check your door thickness before ordering.
How do I choose the right screw length?
Measure the thickness of your door or drawer front. Then choose a screw that is about 5mm longer than that measurement. For a 30mm door, pick a 35mm screw. For a 15mm door, pick a 20mm screw. Use the 5mm rule for a safe fit.
Are these screws compatible with all M4 components?
These are standard M4 metric machine screws with a 4mm thread diameter. They fit any handle or knob that uses an M4 threaded insert. Most Plank Hardware handles and knobs use this standard. Check your hardware's thread specification if unsure.
How many screws come in a pack?
Each pack contains 10 screws. That's enough for 5 handles (2 screws each) or 10 knobs (1 screw each), with spares. Order one pack per hardware set.
