Bolt anchor

Bolt anchors, also known as expansion anchors, wedge anchors, or through-bolts, are mechanical fasteners designed for high-load fixings into solid base materials such as concrete, brick, or stone. These anchors consist of a threaded bolt, a conical expansion sleeve, and a nut and washer assembly. When the nut is tightened, the expansion sleeve is drawn up the cone, forcing it to expand radially against the walls of the pre-drilled hole, creating a secure mechanical interlock. Bolt anchors are available in various diameters (e.g., M6 to M24), lengths, and material grades, including zinc-plated carbon steel, hot-dip galvanized steel, and stainless steel (A2/A4) for corrosion resistance. They are typically rated for static and dynamic loads, with pull-out and shear values specified per manufacturer standards. The installation requires a precise hole diameter and depth, with cleaning of debris to ensure optimal expansion and holding strength.

Bolt anchors are widely used in industrial, commercial, and infrastructure sectors for securing heavy equipment, structural steelwork, machinery bases, cable trays, piping supports, and electrical enclosures to concrete floors, walls, and ceilings. Common applications include mounting of electrical panels, switchgear, motor bases, conveyor systems, and overhead crane rails. They are also employed in seismic bracing systems and safety barriers. The anchors perform reliably in both indoor and outdoor environments, with stainless steel variants suitable for harsh conditions such as chemical plants, marine facilities, and wastewater treatment plants.

Within the bolt anchor category, key subcategories include wedge anchors, sleeve anchors, and drop-in anchors. The most common article codes follow a pattern such as BA-M10x100-ZN, where BA denotes bolt anchor, M10 indicates thread size, 100 is the length in millimeters, and ZN specifies zinc-plated finish. Other variants include BA-M12x150-SS for stainless steel, and BA-M16x200-HDG for hot-dip galvanized. These codes help identify the specific dimensions, material, and coating required for the application. The category also includes anchors with hex head or hex nut configurations, and those designed for flush mounting or protruding installations.
