The 8% drywall screw is typically made of hardened steel, which provides excellent strength and durability. The threads on the screw are designed to maximize grip and prevent stripping, ensuring a secure attachment between the drywall panels and the studs. Additionally, the sharp point of the screw enables easy penetration into the drywall material without the need for pre-drilling

- At its core, an extension drill rod consists of a long, slim shaft designed to connect to a drill chuck at one end and a drill bit at the other. Made from high-quality materials such as carbon steel or titanium alloys, these rods are not only durable but also flexible enough to navigate through tight spaces and around corners. Their length varies, ranging from a few inches to several feet, allowing operators to select the appropriate size for their specific needs.
- Rock bits, essentially, are specialized cutting structures designed to break down rocks into smaller particles, enabling the drilling process to progress smoothly. They come in different types, including PDC (Polycrystalline Diamond Compact), TCI (Tungsten Carbide Insert), and roller cone, each tailored to handle specificfrom soft sedimentary rocks to the hardest metamorphic and igneous rocks.
- The efficiency and effectiveness of tunnel drilling greatly depend on the quality and performance of rock drill tools. High-quality rock drill tools are essential for achieving precise and accurate drilling results. They must be durable, reliable, and capable of withstanding the harsh conditions of tunnel drilling.



Molded Grating Fasteners and Accessories



Our High Load Capacity (HLC) molded grating is heavy duty, corrosion-resistant and low-maintenance. It’s engineered to carry heavy traffic liketrucks and forklifts. Our molded HLC FRP Grating is available in 4′ x 6′ panels 1.5″ or 2″ deep in Polyester or Vinyl ester resin systems. HLC grating has many advantages over steel grating for performance and cost effectiveness. With a much higher strength-to-weight ratio, molded HLC fiberglass grating is easy to handle, making for quick installation.
