Hex Socket Head Knurled with Cutting Groove Concrete Screw 16–10×90

Product Features
Dual-Drive Flange Head for Anti-Loosening and Compression Resistance: The external hex flange is equipped with knurled anti-slip serrations, eliminating the need for washers and preventing surface indentation; the internal hex socket withstands high torque, reducing the risk of cam-out during installation. Compatible with both wrenches and impact drivers.
Knurled Coarse-Thread Shank for Strong Anchoring: The knurling on the shank provides mechanical interlocking, enhancing pull-out and shear resistance; the widely spaced coarse threads ensure smooth debris clearance during driving, preventing jamming in the wall and maintaining long-term load-bearing stability without loosening.
Cutting-Groove Tip for High Efficiency: The cutting grooves at the tip effectively chip away cement dust during driving, eliminating the need for pre-drilling or pre-installed expansion anchors—securing the anchor in a single step, with reduced risk of breakage in long-length applications.
Thermal Rust-Proof Silver Coating for Lasting Corrosion Resistance: The multi-layer composite anti-corrosion process offers salt spray performance far superior to ordinary zinc plating, resisting rain, coastal salt spray, and alkaline corrosion. It is wear-resistant, non-peeling, and its matte silver finish complements metal profiles.
Hardened High-Carbon Steel for Load-Bearing Durability: Through heat treatment, the material achieves a balanced hardness and toughness, enabling direct cutting into hard concrete and meeting the anchoring requirements for heavy-duty brackets and framing.
