Product Overview
The 90 Degree L-Shape Expansion Sleeve Anchor Hook Bolt is a high-performance mechanical fastener developed by Donghuang (a trusted hardware trademark) to solve heavy-duty anchoring challenges in construction and machinery sectors. Crafted from premium Carbon Steel and finished with a thick Yellow Zinc Plated coating, it is specifically optimized for securing electric water equipment, structural elements, and heavy fixtures to both cracked and non-cracked concrete. Unlike generic anchors, its unique L-shape design eliminates the need for extra brackets, making it a one-stop solution for hanging or fixing objects in tight spaces. Compliant with global standards including DIN, ANSI, and GB, this anchor ensures seamless integration into international projects.
This anchor excels in diverse scenarios: it secures heavy equipment (such as industrial pumps and motors), stabilizes electrical and plumbing fixtures (like water heaters and pipe racks), supports outdoor installations (e.g., billboards and solar panels), and enhances home decoration projects (such as wall-mounted cabinets). Its ability to withstand seismic loads also makes it a top choice for earthquake-prone regions, ensuring long-term stability even under sudden force impacts.
Product Appearance
Design and Material Details
The anchor’s most distinctive feature is its 90 Degree L-Shape hook, which is precision-forged to maintain structural integrity under tension. The main body is made of high-tensile Carbon Steel, providing exceptional rigidity to resist bending or breaking. The Yellow Zinc Plated finish not only gives it a bright, uniform yellow appearance but also forms a protective barrier against rust and scratches. The expansion sleeve— a critical component— is engineered to fit tightly with the screw shank, ensuring smooth expansion during installation. Additionally, the bolt head adopts a standard hexagonal design for easy tightening with common tools (e.g., wrenches).
Size and Packaging
To meet varied project needs, the anchor is available in lengths ranging from 18mm to 400mm, covering shallow to deep installation requirements. It is packaged in a durable Box+Carton+Pallet configuration: individual bolts are placed in small boxes to prevent friction damage, multiple boxes are packed into cartons, and cartons are stacked on pallets for safe transportation. Each package is labeled with the Donghuang trademark and size information for quick identification.

Core Advantages
Exceptional Seismic and Shear Resistance
Engineered for seismic load compatibility, the anchor maintains stability during earthquakes, a critical advantage for safety-focused projects. The optimized interaction between the screw shank and expansion sleeve delivers outstanding shear load resistance, preventing bolt failure under lateral pressure—perfect for securing heavy machinery that vibrates during operation.
Effortless Installation Process
Installing the 90 Degree L-Shape Expansion Sleeve Anchor Hook Bolt requires three simple steps: drill a hole matching the anchor’s diameter, hammer the anchor into the hole (with minimal force), and tighten the nut with controlled torque. The low energy needed for hammering reduces labor fatigue and cuts installation time by up to 25% compared to traditional anchors.
Even Load Distribution and Durability
By spreading load forces evenly across the concrete surface, the anchor avoids cracking or damaging base materials— a common issue with low-quality anchors. The Yellow Zinc Plated finish boosts corrosion resistance, extending the product's lifespan by 60% in humid environments (e.g., basements or bathrooms) compared to unplated alternatives.
Versatility and Standard Compliance
With sizes from 18mm to 400mm, it adapts to projects of all scales, from small home repairs to large industrial installations. Compliance with DIN, ANSI, and GB standards guarantees that the anchor meets strict quality criteria, making it a reliable choice for clients worldwide.
