M4×21 mm Expansion Screws 15 pcs Steel Hollow Wall Plugs for Fixing into Plasterboard and Hollow Walls
You already have the maximum available quantity in your cart.
M4×21 mm expansion screws are a practical solution for securing items to hollow walls and plasterboard structures. The design of the hollow plug allows for expansion within the material, creating a stable and secure fixing. This type of fastening material is suitable for general interior mounting tasks.
The set includes 15 pieces of expansion screws that can be used for installing various elements such as shelves, brackets, or lightweight structures. With compact dimensions of M4×21 mm, it is a universal solution for standard use in both home and workshop.
Each piece is made from durable metal material, ensuring sufficient resistance under normal loads. The design is intended to expand the rear part of the plug during tightening, which presses against the inner side of the wall, thereby ensuring the stability of the joint.
The expansion mechanism is ideal for use in materials where traditional screws cannot be used. This principle allows for even distribution of pressure within the wall, which helps to increase the strength of the fixing.
It is particularly suitable for use in plasterboard, hollow bricks, and other lightweight building materials. The screws can be used for installations in homes, workshops, and during minor construction modifications.
