Product Details
Duojia’s CLOSED HEAD SLEEVE ANCHOR, with its Israeli closed-head and double-sleeve configuration, is fabricated in our expansive Yongnian District plant, leveraging advanced techniques for fasteners that excel in stability and corrosion resistance. The carbon steel body, plated in white zinc, includes a hex nut for effortless tightening and a closed head that seals against dust, paired with dual sleeves for double the expansion force. Our 5,000+ square meter operation employs cold pressing, stamping, and welding robots to deliver up to 500 tons monthly, maintaining precision across batches. Installation involves drilling a matching hole, cleaning it, inserting the anchor flush, and tightening the hex nut to expand the sleeves—avoid overtightening to preserve integrity. Ideal for mounting heavy items in construction or industrial sites, it undergoes stringent grade and plating inspections with AAA certification. Customization from prototypes to mass production is available, supported by professional after-sales including replacements within three weeks for defects. Distributed worldwide, this anchor aligns with Duojia’s sustainable focus, offering a sealed, high-strength solution for secure fixings in contaminated or high-vibration areas, ensuring long-term reliability for infrastructure and equipment.

Product Features
The CLOSED HEAD SLEEVE ANCHOR sets a new standard with its Israeli-inspired closed head and double-sleeve system on zinc-plated carbon steel, offering debris resistance and amplified holding power that outperforms single-sleeve variants in contaminated or high-load situations. Precision-machined for uniform expansion, the hex nut enables controlled tightening, while the closed design prevents blockages, enhancing longevity in outdoor or industrial exposures. Certified through load and corrosion tests under AAA protocols, it accommodates customizations like alloy enhancements for extreme durability. Duojia’s optimized production ensures economical, scalable supply for wholesale, with minimal downtime. This anchor’s innovative dual-sleeve and sealed head minimize failure risks, distributing forces evenly to reduce substrate stress, making it an elite choice for applications demanding precision, strength, and maintenance-free performance in challenging setups.
Product Applications
The CLOSED HEAD SLEEVE ANCHOR is pivotal for construction, anchoring steel beams or panels to concrete in buildings where its closed head shields against debris in dusty sites. In industrial settings, it mounts heavy machinery or conduits in factories, leveraging double sleeves for vibration-proof stability. For infrastructure, it’s employed in securing fixtures to masonry or stone in bridges or tunnels, resisting environmental wear. Duojia exports to countries like Germany, Brazil, and Indonesia, with easy deployment: drill, clean, insert flush, and tighten the hex nut for dual expansion—inspect in heavy-load contexts. It’s also suitable for renovations, fixing elements in commercial or residential structures. This anchor’s sealed, robust design serves heavy industry and general fixing, enabling clean, secure installations that boost safety and efficiency in debris-prone or high-stress environments.
