HROMIGRY 5/8″ x 5″ Concrete Anchors
Diameter 5/8″, length 5″, pack of 25. Minimum embedment 2-3/4″, thread length 2-7/8″. Designed for solid concrete and cement, with a pull-out load of 8360 lbf. Best for general structural anchorage in dry or moderately moist environments.
Best for: contractors or DIYers who need bulk supply for multiple anchor points in solid concrete. Choose this if you want a cost-effective option with a robust zinc-plated finish to resist rust over time.
Caution: Not recommended for use in block or brick base materials. Ensure proper embedment depth and clean, drilling debris-free holes for maximum pull-out resistance.
Mighty Fasteners 304 Stainless Steel Wedge Anchors
Diameter 1/2″ x 8″, 5-pack. Made from 304 stainless steel, providing corrosion resistance suitable for indoor and outdoor concrete fastening. Includes nuts and washers for easy installation and mounting of fixtures, brackets, or equipment to solid concrete.
Best for: environments where corrosion resistance is important but the anchor size is flexible to 1/2″. Better for indoor or well-ventilated outdoor areas where a smaller-diameter anchor suffices.
Limitation: Not the exact 5/8″ size, but useful for size-compatible projects where 1/2″ anchors are sufficient or when comparing to 5/8″ options.
Red Head TruBolt 5/8 x 5 Inch Wedge Anchors
ICC-ES ESR-2251 listed, designed for uncracked concrete; engineered to secure machinery and structural supports. Provides a 360-degree contact anchor process for stronger performance in solid concrete, with a straightforward installation.
Best for: projects requiring certified, code-compliant anchorage for heavy machinery or structural components. Choose this for formal compliance and reliable long-term holding power.
Caution: ESR listing applies to uncracked concrete; consult project conditions to ensure the substrate is appropriate for the intended load.
Wej-It PD58 Drop-in Anchor 5/8″
Drop-in anchor with a wedge mechanism to secure within solid masonry and solid uncracked concrete. The zinc-plated carbon steel body expands via a wedge clip to lock in place. Meets 2000 International Building Code and 2000 International Residential Code specifications.
Best for: installations where a flush, low-profile anchor is desired and code compliance is a priority. Choose this if you need a drop-in option in solid concrete with straightforward installation.
Limitation: Requires a predrilled hole and a specific installation procedure; not ideal where deep embedment or very high withdrawal loads are expected, compared to traditional wedge anchors.
Buying Guide
What size and material should I choose?
For 5/8″ wedge anchors, steel or stainless steel variants offer different corrosion resistance. Choose carbon steel with zinc plating for general indoor use and cost efficiency. For outdoor, marine, or humid environments, stainless steel (304 or 316) provides superior corrosion resistance, though at a higher cost.
Which anchor type suits my application?
Wedge anchors are ideal for securing machinery, structural supports, base plates, and heavy fixtures to solid concrete. Drop-in anchors are better when flush installation is preferred or when the hole must remain unobstructed after setting. Ensure your base material is solid concrete rather than block or brick unless explicitly rated for those substrates.
What installation considerations matter?
- Drill accuracy: use the correct drill bit size and clean the hole before inserting the anchor.
- Embedment depth: follow minimum embedment to achieve required pull-out resistance.
- Load direction: verify whether anchors are rated for axial or shear loads in your design.
- Corrosion exposure: outdoor or marine projects should favor stainless steel types to prevent rust.
How to compare across products?
Look at diameter, length, material, corrosion resistance, and practical load capabilities. A longer anchor often means higher embedment and stronger pull-out resistance, but ensure it fits your hole depth and fixture thickness. Certifications or building-code approvals (like ESR listings) add confidence for critical structural uses.
Which option fits a budget-conscious project?
Carbon steel anchors with zinc plating are typically the most economical choice for indoor use. If you need quantity, bulk packs (like 25-piece sets) can lower per-anchor cost while meeting project requirements.

FAQ
- What does 5/8″ refer to in wedge anchors?
– The diameter of the anchor shank that goes into the drilled hole. - Are stainless steel wedge anchors better than standard carbon steel?
– Yes, in terms of corrosion resistance, especially outdoors or in marine environments. - Can I use 5/8″ anchors in block or brick?
– Wedge anchors are designed for solid concrete; do not use in block or brick unless the product specifically tolerates those substrates. - Do I need special tools to install wedge anchors?
– A hammer drill with the correct bit and a wrench for nut-and-washer assemblies is typical; check product-specific instructions for any unique steps.
