Exceptional Holding Power & Shear Strength

The 5.0mm coarse - thread design ensures tighter and more secure engagement with drywall, surpassing traditional pre - drilled toggle anchors. Even under a 2mm micro-movement,
ZSM4B delivers shear strength comparable to high-quality self-drilling drywall anchors, providing unparalleled stability in a variety of applications.

Superior Compatibility & Damage Repair

The 17mm threaded body, 10.5mm effective drilling diameter, and self-tapping metal drill tip of the ZSM4B allow it to seamlessly and effectively replace most drywall anchors or
plugs, especially when existing anchors have loosened or left significant holes in the drywall. This makes ZSM4B an ideal solution for repairing and reinforcing previously compromised
installations.

Innovative Design for Maximum Load Capacity

Unlike conventional drywall anchors or plugs, where screws merely fasten the anchor and object together, ZSM4B's innovative structure allows the screw, ZSM4B, and drywall to form a unified, integrated system under a 5Nm torque load. This not only enhances shear strength but also significantly improves pull-out resistance, making ZSM4B comparable to the best pre-drilled toggle anchors. Even under a 2mm micro - movement, the high shear strength and pull - out resistance of ZSM4B provide heavy - duty load - bearing capacity with outstanding anti - loosening performance. This makes it ideal for securely mounting frequently touched items and valuable objects on drywall walls or ceilings, offering excellent vibration resistance and long - term stability.

Smart Design for Easy & Reliable Installation

Thanks to its intelligent engineering and superior manufacturing quality, ZSM4B can be installed using either a power screwdriver or a manual screwdriver, and even a 12V impact driver for effortless installation. When used with the patented M4x58mm screw, it requires no special training, ensuring zero installation failures. Additionally, on 15.5mm thick drywall, ZSM4B achieves an impressive 30mm fastening depth, further demonstrating its exceptional holding power and reliability.
