HROMIGRY 3/4” x 10” Concrete Anchor Bolts (L Shaped, 10 Pack)
These 3/4 in. x 10 in. anchor bolts are designed to attach bottom plates and sill plates to concrete or masonry foundations. The set includes nuts and USS washers and uses hot-dip galvanized carbon steel for improved strength and corrosion resistance, suitable for outdoor use. Best for exterior installations where rust resistance matters and where bottom plates require strong fastening. Caution: ensure the thread length of 4 in. is compatible with your plate thickness.
HROMIGRY 3/4” x 10” Concrete Anchor Bolts (L Shaped) With Large Square Plate Washers
This variant uses square plate washers (3 x 3 in.) for enhanced load distribution, making it ideal when attaching bottom or sill plates to concrete or masonry foundations. Made from carbon steel with a hot-dip galvanized finish for outdoor durability. Best for projects requiring larger bearing surfaces to reduce concrete stress. Limitation: plate washers add bulk, which may require extra clearance in tight spaces.
HROMIGRY 3/4” x 10” J Bolt Anchors (10 Pack)
These J bolts are designed for anchoring sill plates and securing structural components to concrete or masonry foundations. They include nuts and USS washers, are carbon steel, and feature a hot-dip galvanized finish for outdoor use. Best for applications needing a curved form that grips around wood or metal members. Consideration: J bolts may require precise bending on site to fit specific layouts.
3/4″ x 10″ Zinc-Plated Wedge Anchors (Box of 10)
These wedge anchors are heavy-duty carbon steel with a zinc finish, designed for reliable hold in concrete, cement, and fully grouted CMU. They are suitable for most indoor or dry outdoor installations where a straightforward drilling and setting process is preferred. Best for long-term anchorage with steady load requirements. Limitation: not recommended for block or brick base materials.
HROMIGRY 3/4″ x 10″ Concrete Anchors (10 Pack) Zinc Plated
These 3/4 inch by 10 inch anchor bolts are zinc-plated, providing rust resistance for long service life. They are a one-piece design with high load capacity, non-expansion, and removable, making them suitable for certain temporary or adjustable installations. Best for projects where ease of removal and reconfiguration is needed. Limitation: non-expansion design means they rely on the concrete’s inherent friction for holding power.
HROMIGRY 3/4″ x 10″ Concrete Screws (10 PCS) Zinc Plated
These 3/4 inch x 10 inch concrete anchors are hex-head, carbon steel, and zinc plated for corrosion resistance. They provide a high-load, non-expansion, removable option with quick installation. Best for projects requiring straightforward screwing into solid concrete. Caution: ensure the substrate can accept screws without risk of cracking in very dense concrete.
Sandbaggy 3/4″ x 10″ Threaded Concrete Anchor L-Bolts
These threaded L-bolts include nuts and washers for a hassle-free installation. They are hot-dipped galvanized for outdoor durability and suitable for sill plates, base plates, masonry, and wood on concrete foundations. Best for DIY projects or professionals needing a complete kit with hardware. Caution: verify the load path and footing depth to ensure secure anchorage under heavy loads.
Buying Guide
Key factors to consider when selecting 3/4 x 10 anchor bolts:
- Material and finish: Hot-dip galvanizing or zinc plating improves corrosion resistance for outdoor or damp environments.
- Head type and compatibility: L-shaped, J-bolt, or wedge anchors determine suitability for different attachment points (plates, columns, or structural members).
- Embedment depth and thread length: Ensure the 4 in. thread length matches the base plate thickness and concrete depth.
- Load requirements: Higher loads may require plate washers or wedge anchors with larger bearing surfaces.
- Installation context: Outdoor use, treated lumber, or CMU vs solid concrete can change the best choice.
- Hardware included: Nuts and washers availability can simplify installation (present in several options).
FAQ
- What is the standard diameter and length of these anchors?
– Most options are 3/4 inch diameter and 10 inches long, with a 4-inch thread length. - When should I use wedge anchors vs L-shaped bolts?
– Wedge anchors are ideal for solid concrete with high load needs; L-shaped bolts are common for securing plates and sill bases. - Do these kits come with nuts and washers?
– Several products include nuts and USS washers; check the product details for confirmation. - Can I install these outdoors?
– Yes, many are hot-dip galvanized or zinc-plated for outdoor durability, but verify suitability for your climate and exposure. - Is a drill bit size provided or required?
– The kit descriptions imply standard installation; follow manufacturer recommendations for drill bit diameter in your concrete. - Are these anchors suitable for CMU or block?
– Wedge anchors typically work best in solid concrete; some products specify CMU suitability; confirm substrate before purchase.
