Low Carbon Hex Head Lag Screw Clear Zinc Cr3 Plating

Low Carbon Hex Head Lag Screws – Clear Zinc Cr3 Plated for Clean, Corrosion-Resistant Performance

Low Carbon Hex Head Lag Screws with Clear Zinc Cr3 plating deliver dependable structural fastening with a bright, professional finish. Designed for wood-to-wood and wood-to-masonry applications, these lag screws provide strong clamping force while offering moderate corrosion resistance for interior and light exterior environments. Ideal for framing, ledger board attachment, subflooring, cabinetry, and equipment mounting, they combine durability with clean aesthetics.

Low Carbon Steel Construction for Reliable Strength

Manufactured from ductile low carbon steel, these hex head lag screws offer an excellent balance of tensile strength and flexibility. The lower carbon content reduces brittleness, helping prevent cracking under load while maintaining solid holding power. This makes them well-suited for structural lumber connections and general carpentry applications. Precision-rolled coarse threads ensure secure wood engagement and consistent performance across a variety of materials.

Hex Head Design for High-Torque Installation

The hex head configuration allows installation with a wrench or socket, enabling greater torque application than traditional screws. This ensures tight material draw-down and secure structural connections. For best results, pilot holes are recommended to prevent wood splitting and ensure proper alignment during installation.

Clear Zinc Cr3 Plating for Enhanced Corrosion Resistance

The Clear Zinc Cr3 (trivalent chromium) coating provides a protective barrier against rust and oxidation while maintaining a clean, silver-like appearance. Unlike older hexavalent coatings, Cr3 plating is RoHS-compliant and environmentally safer. This finish offers reliable corrosion resistance for indoor use and covered outdoor projects where exposure to moisture is limited.
