Product Introduction
Standard Name: L-Type Anchor Bolt or Bent Anchor Bolt.
Common Names: L-shaped anchor bolt, right-angle embedded bolt, hook-type anchor bolt.
Product Definition: A pre-embedded anchor bolt featuring one end bent at a 90-degree angle (L-shape) and the other end threaded. Embedded before concrete pouring, the L-shaped end hooks onto internal steel reinforcement, providing strong pull-out and shear resistance. Used for permanently securing equipment, columns, steel structure foundations, etc.
Anchor Bolt L Type ZP Key Features
Zinc Plated (ZP) Coating: Provides basic rust protection and a bright silver finish, enhancing corrosion
resistance, suitable for indoor or mildly humid environments.
L-shaped Design: One end is bent into a 90° L-shaped hook for embedding in concrete foundations,
providing resistance against pull-out and shear forces; the other end is threaded and comes with a
nut and washer.
Material and Strength: Commonly made of carbon steel, with a high-strength design, suitable for heavy
structural loads.
Diverse Specifications: Diameters from M12 to M48, with customizable hook length and thread length,
usually supplied with nuts and flat washers.
Advantages: Stable embedding, seismic resistance, durable, and cost-effective, commonly used for
foundation fixing.

Working Principle
Pre-embedding Installation: The L-shaped hook end is embedded in the concrete pour, with the threaded
end exposed.
Curing and Fixing: After the concrete hardens, the L-hook provides mechanical interlocking, resisting
pull-out and shear forces.
Load Transfer: Tightening the nut generates axial clamping force, evenly distributed to the foundation.
Corrosion Protection: The zinc plating reduces friction and provides mild corrosion protection; the
principle involves mechanical embedding and frictional grip.

Product Applications
Construction Engineering: Fixing steel columns, wall panels, or equipment to concrete foundations,
providing stability.
Infrastructure: Anchoring bridges, towers, or guardrail foundations, resisting wind loads and earthquakes.
Industrial Equipment: Fastening heavy machinery or supports to foundations.
Steel Structures: Connecting beams and columns to foundations; zinc plating is suitable for indoor or
mildly exposed environments.
General Foundations: Any project requiring embedded high-strength anchoring.
