Usdrwam 3/8″ × 4″ Concrete Anchor Bolts
These ASTM A36 carbon steel wedge anchors deliver robust performance with a 70,000 PSI tensile strength and hot-dip galvanizing for corrosion resistance. The package includes 10 anchors, nuts, and washers, designed for anchoring metal plates, steel angles, or wood into concrete. Install by drilling a hole slightly deeper than the anchor, clean debris, insert flush to the surface, and torque the nut until fully expanded for a secure hold. Suitable for structural, shelving, and machinery mounting in dry indoor settings.
HROMIGRY 5/8″ x 5″ Concrete Anchors (25 Pack)
This 25-pack of 5/8″ by 5″ carbon steel wedge anchors provides a heavy-duty solution for concrete and solid cement bases. Zinc plating protects against rust, extending service life in demanding installations. Use with a carbide-tipped drill to create a properly sized vertical hole, then insert and tighten to expand the wedge against the concrete. Ideal for mounting heavy equipment, structural brackets, and railing systems in solid concrete environments.
Surge Building Products 1/2″ x 5-1/2″ Concrete Anchors
These heavy-duty wedge anchors are zinc-plated to resist corrosion in indoor environments and tailored for reliable performance in solid concrete and fully grouted CMU blocks. A straightforward drilling and tightening process ensures clean results and strong anchorage. They are designed for general mounting tasks, including machinery, handrails, and structural components, where a consistent, one-size-fits-all drill bit is convenient.
HROMIGRY 3/4″ x 5-1/2″ Concrete Anchors (10 Pack)
With a 3/4″ diameter and 5-1/2″ length, these carbon steel wedge anchors are finished with zinc plating to prevent rust and ensure durability across tough installations. They are suitable for mounting heavy equipment, structural components, and other applications in solid concrete. Do not use in block or brick masonry. The pack includes ten anchors, making them a practical choice for larger projects requiring significant anchorage strength.
Usdrwam 10Pcs 5/16″ × 3-1/8″ Concrete Anchor Bolts
Light to medium-duty anchors, these 5/16″ by 3-1/8″ wedge anchors offer a reliable hold for mounting brackets, handrails, or fixtures to concrete. Constructed from ASTM A36 carbon steel with a hot-dip galvanized finish, the set includes 10 anchors with nuts and washers for straightforward installation. Follow the standard drill depth and torque guidelines to achieve full expansion and maximum load-bearing capacity in solid concrete.
Usdrwam 10Pcs 4″ Concrete Anchor Bolts
These 4″ wedge anchors from Usdrwam provide extended embedment for heavier loads in concrete and masonry. The kit includes ten anchors with standard nuts and washers, suitable for securing structural elements, brackets, and equipment. The product emphasizes corrosion resistance and deformation resistance, ensuring stable performance over time in demanding environments. Install with vertical hole drilling, debris cleaning, flush seating, and precise nut torque to activate full expansion.
Buying Guide: Key Purchase Considerations
- Material and corrosion resistance: Look for carbon steel with zinc plating or stainless variants for durability in indoor and outdoor settings. Consider whether hot-dip galvanizing is offered for extra rust protection in damp environments.
- Anchor size and embedment depth: Match the diameter and length to the load requirements and the concrete strength. Deeper embedment generally increases pull-out resistance, but ensure the hole depth is achievable with your drill.
- Concrete type compatibility: Ensure the anchors are appropriate for solid concrete, cement, or fully grouted blocks. Some anchors are not recommended for hollow or block masonry.
- Load capacity and safety factors: Review the rated pull-out loads or tensile strength to determine suitability for the intended mounting. Always apply appropriate safety factors for critical installations.
- Installation method and tools: Confirm drill bit size, drilling depth, debris removal steps, and torque requirements. Use carbide-tipped bits for clean, precise holes and recommended torque values for full expansion.
- Quantity and packaging: For larger projects, consider multi-pack configurations that include nuts and washers, reducing the need for additional hardware.
- Application-specific considerations: Weight-bearing shelves, machinery mounts, handrails, and outdoor installations may require different materials or coating types. Plan for environmental exposure and maintenance access when selecting anchors.
- Warranty and brand reliability: Rely on reputable brands with documented performance in concrete to minimize installation risk and ensure long-term stability.
