Self-Drilling Lath Screws

Self-Drilling Lath Screws – Product Introduction

Self-Drilling Lath Screws are professional high-strength fasteners specially designed for fixing metal lath, plaster lath, wire mesh and other lath materials to steel studs, wooden studs or concrete substrates. Integrating self-drilling, self-tapping and high-load-bearing functions, they are equipped with a sharp drill point and precision-threaded shank, which can directly drill through metal lath and form tight threads in the base material without pre-drilling. Widely used in building plastering, wall reinforcement, ceiling installation and industrial maintenance projects, these screws are highly trusted by global contractors, construction companies and bulk purchasers for their efficiency, stability and durability.

Core Advantages

Integrated Self-Drilling & Self-Tapping, High Efficiency: The sharp carbide drill point can easily penetrate 0.5-3.0mm metal lath and thin steel studs, and the precision thread completes tapping and fixing in one step. No pre-drilling tools or additional operations are required, which reduces construction steps by 60% and greatly improves work efficiency.
Strong Load-Bearing Capacity, Stable Fastening: The thickened shank and deep thread design enhance the contact area with the base material, providing excellent tensile force and shear force. The screws are not easy to loosen or slip even under long-term load, ensuring the stability of lath fixing and wall reinforcement.
Wear-Resistant & Corrosion-Resistant, Long Service Life: Made of high-quality C1022A medium carbon steel or 304/316 stainless steel, through quenching, tempering and professional surface treatment, the surface hardness reaches HRC48-55, the drill point is wear-resistant and not easy to blunt, and the anti-corrosion performance meets the requirements of indoor and outdoor harsh environments.
Universal Compatibility, Wide Adaptability: Suitable for fixing various lath materials (metal lath, plaster lath, wire mesh, fiber lath) to different substrates (steel studs, wooden studs, light concrete), and compatible with most electric screwdrivers and cordless drills on the global market.
Safe & Reliable, Easy to Operate: The drill point and thread are precisely processed, with smooth feeding during installation, no jamming or breakage. The reasonable head design ensures that the lath is tightly attached to the substrate without damaging the lath surface, avoiding potential safety hazards caused by loose fixing.
