In U.S. projects, ASTM F1554 grades such as 36, 55, and 105 are commonly referenced for anchor rods.<\/p>\n\n\n\n<p>For higher-load projects, review <a href=\"https:\/\/xzfastener.com\/es\/products-category\/high-strength-fasteners\/\">high-strength fasteners<\/a> and confirm tensile, yield, and proof-load requirements.<\/p>\n\n\n\n<p>Coating must also be defined. Hot-dip galvanizing, zinc plating, zinc flake, epoxy, or stainless steel may be used depending on exposure. For outdoor or underground projects, compare <a href=\"https:\/\/xzfastener.com\/es\/products-category\/various-coated-fasteners\/\">various coated fasteners<\/a> before approval.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Dimensions Buyers Must Not Miss<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Critical Anchor Dimensions<\/h3>\n\n\n\n<p>A complete RFQ should include:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Diameter and thread pitch<\/li>\n\n\n\n<li>Overall length<\/li>\n\n\n\n<li>Longitud del hilo<\/li>\n\n\n\n<li>Embedment depth<\/li>\n\n\n\n<li>Projection above concrete<\/li>\n\n\n\n<li>Bend, hook, head, or plate dimensions<\/li>\n\n\n\n<li>Nut and washer requirements<\/li>\n\n\n\n<li>Base plate hole size<\/li>\n\n\n\n<li>Coating thickness requirement<\/li>\n<\/ol>\n\n\n\n<p>For washers, confirm ID, OD, thickness, hardness, and finish.
