Its holding power is achieved by the expansion of the sleeve when torque is applied to the nut.<\/li>\n<li><strong>Hook Bolt Head:<\/strong> Unlike standard sleeve anchors that have a hex bolt or nut for clamping flat objects, this version features a permanently formed hook. This makes it ideal for suspending items using chains, cables, wires, or ropes without needing additional hardware.<\/li>\n<li><strong>&#8220;YZP&#8221; (Yellow Zinc Plated):<\/strong> This refers to the anchor&#8217;s surface treatment. The carbon steel components are electro-plated with zinc and then passivated with a yellow chromate conversion coating. This finish provides a higher level of corrosion resistance compared to standard white\/blue zinc plating, making it suitable for indoor applications where some moisture or humidity may be present.<\/li>\n<li><strong>Note on Inconsistency:<\/strong> It is important to note a discrepancy in the provided source material. While the URL and a portion of the product introduction mention &#8220;WZP&#8221; (White Zinc Plated), the product title, the detailed parameters table, and the product tags all correctly specify <strong>&#8220;YZP&#8221; (Yellow Zinc Plated)<\/strong>. This description is based on the more prominent and detailed YZP specification.<\/li>\n<\/ul>\n<h4><strong>Product Mechanism and Installation<\/strong><\/h4>\n<p>The anchor creates a secure hanging point through the controlled expansion of its sleeve.<\/p>\n<ul>\n<li><strong>Mechanism:<\/strong> The anchor assembly features a hook bolt with a tapered conical section at its threaded end. This cone sits inside the expansion sleeve. When the hex nut is tightened, it pulls the hook bolt&#8217;s shaft upwards. This action draws the tapered cone into the sleeve, forcing the sleeve to expand outwards and press firmly against the inner walls of the drilled hole, creating a strong frictional hold.<\/li>\n<li><strong>Installation Process:<\/strong>\n<ol>\n<li><strong>Drill the Hole:<\/strong> Using a carbide-tipped drill bit that matches the anchor&#8217;s diameter, drill a hole into the base material (e.g., concrete). The hole must be drilled to a depth sufficient to accommodate the full length of the anchor sleeve.<\/li>\n<li><strong>Clean the Hole:<\/strong> Thoroughly remove all dust and debris from the drilled hole using a brush and compressed air or a hand pump. A clean hole is essential for achieving the anchor&#8217;s maximum holding power.<\/li>\n<li><strong>Insert the Anchor:<\/strong> Insert the complete hook bolt sleeve anchor assembly into the hole until the washer and nut are flush with the surface of the base material.<\/li>\n<li><strong>Orient and Set the Anchor:<\/strong> Before fully tightening, orient the hook to the desired direction. Using a wrench, turn the hex nut clockwise. This will expand the sleeve and securely set the anchor. Continue to tighten until the anchor is firm and does not turn in the hole.<\/li>\n<\/ol>\n<\/li>\n<\/ul>\n<h4><strong>Product Parameters<\/strong><\/h4>\n<div class=\"MarkdownTable_tableContainer__2k5Kh\" tabindex=\"0\" role=\"region\">\n<table>\n<thead>\n<tr>\n<th>Parameter Item<\/th>\n<th>Specification Description<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Product Name<\/strong><\/td>\n<td>Hook Bolt Sleeve Anchor YZP<\/td>\n<\/tr>\n<tr>\n<td><strong>Brand Name<\/strong><\/td>\n<td>Duojia<\/td>\n<\/tr>\n<tr>\n<td><strong>Place of Origin<\/strong><\/td>\n<td>Hebei, China<\/td>\n<\/tr>\n<tr>\n<td><strong>Material<\/strong><\/td>\n<td>Carbon Steel<\/td>\n<\/tr>\n<tr>\n<td><strong>Surface Treatment<\/strong><\/td>\n<td>Yellow Zinc Plated (YZP)<\/td>\n<\/tr>\n<tr>\n<td><strong>Available Sizes<\/strong><\/td>\n<td>M6-M20<\/td>\n<\/tr>\n<tr>\n<td><strong>Strength Grades<\/strong><\/td>\n<td>4.8, 8.8, 10.9, 12.9 (Note: The listed A2\/A4 grades refer to stainless steel, which would be a different material option).<\/td>\n<\/tr>\n<tr>\n<td><strong>Measurement System<\/strong><\/td>\n<td>Metric<\/td>\n<\/tr>\n<tr>\n<td><strong>Application<\/strong><\/td>\n<td>Heavy Industry, General Industry, Construction, Infrastructure<\/td>\n<\/tr>\n<tr>\n<td><strong>Certifications<\/strong><\/td>\n<td>ISO9001, ISO14001, ISO45001, SGS<\/td>\n<\/tr>\n<tr>\n<td><strong>Packaging Options<\/strong><\/td>\n<td>Small Pack + Carton + Pallet; Bag\/Box with Pallet<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4><strong>Key Features<\/strong><\/h4>\n<ul>\n<li><strong>Integrated Hanging Point:<\/strong> The built-in hook provides a ready-made, secure point for suspending loads, eliminating the need for extra components.<\/li>\n<li><strong>Reliable Expansion:<\/strong> The torque-controlled sleeve anchor mechanism ensures a strong and consistent hold in solid base materials.<\/li>\n<li><strong>Good Corrosion Resistance:<\/strong> The Yellow Zinc Plating (YZP) offers enhanced durability and protection against rust in indoor and mild environments.<\/li>\n<li><strong>Pre-Assembled for Convenience:<\/strong> The anchor comes as a complete unit, simplifying handling and speeding up installation.<\/li>\n<li><strong>Versatile Use:<\/strong> Ideal for a wide range of overhead and wall-mounted hanging applications in concrete and masonry.<\/li>\n<\/ul>\n<h4><strong>Common Applications<\/strong><\/h4>\n<ul>\n<li><strong>Mechanical &amp; Electrical:<\/strong> Suspending pipework, electrical conduit, HVAC ducting, and cable trays from ceilings.<\/li>\n<li><strong>Lighting:<\/strong> Hanging industrial or commercial light fixtures.<\/li>\n<li><strong>Warehousing:<\/strong> Suspending signage, guide wires, or creating attachment points for temporary partitions.<\/li>\n<li><strong>General Construction:<\/strong> Anchoring guy ropes, support wires, and suspended ceilings.<\/li>\n<li><strong>Home\/Garage:<\/strong> Hanging heavy items like punching bags, plant baskets, or storage solutions from concrete ceilings or walls.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>The Duojia &#8220;Hook Bolt Sleeve Anchor YZP&#8221; is a specialized, torque-controlled expansion anchor designed specifically for hanging and suspending loads from solid base materials such as concrete, brick, and block.
