This edition embeds explicit font sizes and paragraph line spacing as requested.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Definition and Scope<\/h2>\n\n\n\n<p>The Israeli sleeve anchor is a through\u2011fixing expansion fastener comprising a threaded stud, a slotted sleeve, an expansion cone, a washer, and a hex nut. Tightening the nut draws the cone into the sleeve, expanding it radially against the borehole wall and creating friction and localized bearing. The system suits normal\u2011weight concrete, solid brick, and concrete masonry units (CMU), enabling immediate service readiness without adhesive cure time.<\/p>\n\n\n\n<p>LSI keywords used: mechanical expansion anchor, torque\u2011controlled anchor, masonry fastener, through\u2011bolt sleeve anchor, radial expansion, cracked concrete, CMU, ICC\u2011ES, ETA, EN 1992\u20114, ACI 318, zinc\u2011plated steel, 304 stainless steel, 316 stainless steel, edge distance, embedment depth, proof load testing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Components and Operating Principle<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Component Breakdown<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Threaded stud: transfers axial tension and shear loads into the base material.<\/li>\n\n\n\n<li>Expansion cone\/wedge: converts axial draw into radial expansion.<\/li>\n\n\n\n<li>Slotted sleeve: expands against the borehole wall; slot geometry and hardness govern contact stress distribution.<\/li>\n\n\n\n<li>Washer: spreads clamping force beneath the nut.<\/li>\n\n\n\n<li>Hex nut: interface for torque application, controlling expansion.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How Expansion Creates Holding Power<\/h3>\n\n\n\n<p>Applying torque advances the nut while the cone is drawn into the sleeve. The sleeve expands radially, increasing normal stress at the hole interface. Friction plus local bearing provide resistance to tension and shear. Capacity depends on embedment depth, base material compressive strength, hole size and cleanliness, sleeve geometry, edge distance, spacing, and torque accuracy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Selection Criteria: Variant, Size, and Material<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Variants and Head Forms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Through\u2011bolt with hex nut and washer (most common and globally available).<\/li>\n\n\n\n<li>Trim or countersunk heads exist regionally;
