M8 Stainless Steel Concrete Wedge Anchors

Product Overview

Specifically designed for M8 metric thread specifications, this anchor excels in harsh environments where corrosion resistance and structural integrity are critical. Crafted from high-grade stainless steel, it resists rust, saltwater corrosion, and chemical degradation, making it ideal for outdoor, coastal, or industrial settings. The wedge anchor design features a split expansion clip that activates when a bolt is tightened, creating a powerful, permanent bond with concrete substrates. Unlike zinc-plated anchors, the stainless steel construction ensures long-term performance without sacrificing strength, even in extreme temperature fluctuations. Whether used for foundation reinforcement, equipment anchoring, or structural support, the M8 Stainless Steel Wedge Anchor sets a benchmark for reliability in concrete fastening applications.

Technical Specifications

Key Advantages

Exceptional Corrosion Resistance

Made of 304/316 stainless steel, this anchor is impervious to saltwater, humidity, and chemical pollutants. 316 stainless steel variants are especially suited for coastal areas and industrial environments with high chemical exposure.

Precision M8 Thread for Secure Fastening

The standardized M8 metric thread ensures a tight fit with compatible bolts and nuts. It prevents thread slippage and maintains consistent clamping force, even under vibration or dynamic load conditions.

Permanent Wedge-Locking Design

The split wedge clip expands uniformly against the concrete hole walls during installation. This creates a mechanical interlock that eliminates the risk of anchor pull-out, ensuring long-term stability for foundation-mounted structures.

Weather and Temperature Resilience

Stainless steel material withstands extreme temperatures from -50°C to +150°C. It does not deform or degrade in freezing, high-heat, or UV-exposed environments.

Application Scenarios

Concrete Foundation Reinforcement

Used to anchor steel columns, support beams, and foundation bolts in residential and commercial building construction. It ensures the foundation can bear heavy structural loads without shifting.

Outdoor and Coastal Infrastructure

Ideal for securing guardrails, signposts, and solar panel mounts in coastal regions. The stainless steel construction resists salt spray corrosion that would damage conventional anchors.

Industrial and Chemical Plant Use

Suitable for fixing pumps, valves, and pipeline supports in chemical plants and refineries. It withstands exposure to acids, alkalis, and other corrosive substances.

Heavy Equipment Anchoring

Applied to secure generators, compressors, and construction machinery to concrete floors. The wedge-locking design prevents equipment displacement during operation.

Usage Guidelines & Purchase Information

Usage Guidelines

Drilling: Use a hammer drill with a 10mm carbide-tipped bit to drill a hole of at least 40mm depth in the concrete foundation. The hole must be clean and free of cracks.

Debris Removal: Blow out dust and debris with compressed air or a brush. Repeat the process 2–3 times to ensure no residue remains.

Anchor Insertion: Insert the M8 Stainless Steel Wedge Anchor into the hole until it is fully seated. Do not hammer the anchor excessively, as this may damage the expansion clip.

Tightening: Thread an M8 bolt into the anchor and tighten it to the recommended torque (25–30 N·m). Over-tightening may cause the concrete to crack.
