FAQ: PDI hollow screw black M4
Which size should I choose between M4x3, M4x6 and M4x8?
It depends on the thickness of the parts to be fixed. A screw that is too short won’t hold, and one that is too long can interfere or cause damage. You need to adapt it to your assembly.
Is this screw compatible with all replicas?
It is compatible with any component requiring an M4 screw. You just need to check the correct length for your setup.
Can it be used for external accessories?
Yes, absolutely. It works perfectly for mounting rails, supports, or other tactical elements.
Why choose a hollow screw instead of a standard screw?
Allen key tightening is more precise, more reliable, and less damaging to the screw. It is ideal for technical assemblies.
Should thread locker be used?
It is recommended for parts exposed to vibrations, especially on AEGs. It helps secure the assembly over time.
Is it sold individually?
Yes, this screw is sold individually. Convenient for matching your exact needs without unnecessary extras.
