Concrete Frame Screw

Concrete Frame Screw – Product Introduction

Concrete Frame Screws are specialized high-strength anchoring fasteners engineered exclusively for fastening structural components to concrete, masonry, brick, and precast concrete frames. Featuring a hardened drill point, high-torque thread design, and anti-loosening structure, these screws are designed to penetrate concrete frames directly without pre-drilling (or with minimal pre-drilling) and form a tight, secure bond with the base material. Crafted with high-grade alloy steel and precision heat treatment processes, they deliver exceptional tensile and shear strength, making them ideal for heavy-duty structural applications such as building frames, curtain walls, steel structures, and industrial equipment installation. Trusted by global contractors, construction companies, and structural engineers, these screws are recognized for their reliability, durability, and easy installation in harsh construction environments.

Core Advantages

Hardened Drill Point, Easy Penetration: Equipped with a high-hardness (HRC55-60) hardened drill point, specially ground to penetrate concrete, masonry, and precast concrete frames directly, eliminating the need for complex pre-drilling and reaming processes. The drill point design reduces drilling resistance, ensures precise positioning, and avoids concrete cracking during installation.
High-Strength Thread, Superior Anchoring Force: The precision-engineered high-torque thread features a unique pitch and cross-sectional design, which enhances friction and engagement with concrete particles, forming a tight, irreversible anchoring bond. Delivers excellent tensile and shear strength, ensuring long-term stability even under heavy loads and structural stress.
Anti-Loosening & Anti-Vibration Performance: Integrated with anti-loosening thread locking structure and corrosion-resistant sealing ring, the screws effectively resist loosening caused by structural vibration, temperature changes, and long-term use. Suitable for high-vibration environments such as industrial plants, bridges, and high-rise building frames.
Super High Strength & Durability: Made of 10.9/12.9-grade alloy steel or high-strength carbon steel, through quenching, tempering, and surface hardening treatment, the tensile strength reaches up to 1000MPa, and the surface hardness is HRC55-60. The screws are resistant to wear, impact, and deformation, ensuring long service life in harsh construction environments.
Weather & Corrosion Resistance: Available in professional surface treatments such as hot-dip galvanizing, Dacromet, and epoxy coating, which form a dense protective layer on the surface, effectively resisting rust, corrosion, and chemical erosion. Suitable for both indoor and outdoor concrete frame applications, including marine, coastal, and industrial corrosion-prone environments.
