The following description is based on the actual product name, parameters, and general mechanical principles of an L-Hook sleeve anchor.<\/p>\n<ul>\n<li><strong>Anchor Type:<\/strong> This is a <strong>sleeve anchor<\/strong>, a pre-assembled fastener that includes a threaded bolt (in this case, an L-Hook bolt), an expansion sleeve, a washer, and a nut.<\/li>\n<li><strong>L-Hook Bolt Head:<\/strong> The defining feature is the bolt head, which is bent at a 90-degree angle to form an &#8220;L&#8221; shape. This design is specifically intended for applications where items need to be hung or supported at a distance from the anchor&#8217;s surface, such as securing timber battens, brackets, or conduit.<\/li>\n<li><strong>&#8220;YZP&#8221; (Yellow Zinc Plated):<\/strong> This refers to the anchor&#8217;s surface finish. The carbon steel is electro-plated with zinc and then passivated with a yellow chromate conversion coating. This process provides superior corrosion resistance compared to standard white zinc plating, making it suitable for indoor environments where humidity or occasional moisture may be a factor.<\/li>\n<\/ul>\n<h4><strong>Product Mechanism and Installation<\/strong><\/h4>\n<p>The anchor achieves its holding power through the expansion of its sleeve within the base material.<\/p>\n<ul>\n<li><strong>Mechanism:<\/strong> The anchor consists of an L-Hook bolt with a tapered cone at its threaded end, an expansion sleeve, a flat washer, and a hex nut. When the hex nut is tightened, it pulls the bolt&#8217;s shaft upwards. This action draws the tapered cone into the expansion sleeve, forcing the sleeve to expand outwards and press firmly against the inner walls of the drilled hole, creating a secure frictional lock.<\/li>\n<li><strong>Correct 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 depth must be 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 wire brush and compressed air or a hand pump. A clean hole is essential for achieving maximum load capacity.<\/li>\n<li><strong>Insert the Anchor:<\/strong> Insert the complete L-Hook 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, position the L-Hook to the desired orientation (e.g., pointing upwards to support a shelf bracket). 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>L-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 L-Hook:<\/strong> The 90-degree hook provides a ready-made support point for perpendicular or standoff fastening, eliminating the need for additional brackets.<\/li>\n<li><strong>Heavy-Duty Fastening:<\/strong> Designed for high load-bearing capacity in solid masonry and concrete.<\/li>\n<li><strong>Enhanced Corrosion Resistance:<\/strong> The Yellow Zinc Plating (YZP) offers durable protection against rust and corrosion in indoor and mild environments.<\/li>\n<li><strong>Reliable Expansion Mechanism:<\/strong> The torque-controlled sleeve provides a strong and consistent hold.<\/li>\n<li><strong>Pre-Assembled for Convenience:<\/strong> The anchor comes as a complete unit, simplifying handling and speeding up installation.<\/li>\n<\/ul>\n<h4><strong>Common Applications<\/strong><\/h4>\n<ul>\n<li><strong>Construction:<\/strong> Securing timber battens to walls for cladding or mounting panels.<\/li>\n<li><strong>Mechanical &amp; Electrical:<\/strong> Creating standoff points for running pipes, conduit, or cable trays along walls.<\/li>\n<li><strong>Storage and Shelving:<\/strong> Providing support for wall-mounted shelving brackets, tool racks, and storage systems.<\/li>\n<li><strong>General Purpose:<\/strong> Anchoring items that need to be spaced away from a concrete or masonry surface.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>The Duojia &#8220;L-Hook Bolt Sleeve Anchor YZP&#8221; is a heavy-duty, torque-controlled expansion anchor designed to create a strong, right-angled attachment point in solid base materials like concrete, brick, and block.
