Heavy-Duty 3/4″ x 5-1/2″ Wedge Anchors
These wedge anchors from SURGE BUILDING PRODUCTS are designed for reliable holds in concrete, cement, and fully grouted CMU blocks. The carbon steel body offers robust strength for daily-use mounting. They come with a zinc finish to resist corrosion in indoor, dry environments, extending service life in standard workshop settings. Installation is straightforward: the drill bit size matches the anchor diameter, reducing guesswork and ensuring clean results.
Ideal applications include mounting equipment, electrical panels, or fixtures to poured concrete. The box of 20 provides enough anchors for multiple installations, making them a practical choice for contractors and DIY enthusiasts undertaking several anchoring tasks.
3/4″ x 7″ Concrete Anchors (10 Pack)
HROMIGRY’s 3/4″ x 7″ wedge anchors combine carbon steel strength with zinc plating to resist rust and corrosion. A 7-inch length offers extended anchorage for heavier fixtures or high-load mounting scenarios in solid concrete. Suitable for general mounting and structural anchorage in cementitious materials, these anchors are not recommended for use in block or brick bases. The set includes ten pieces, providing a ready supply for single or multiple installations and reducing project downtime.
The anchors are designed for straightforward installation: drill a hole of the same diameter as the anchor, insert, and tighten. This reduces the risk of slippage and helps ensure a secure, vibration-resistant hold in concrete surfaces typically encountered in garages, workshops, or industrial spaces.
3/4″ x 5-1/2″ Wedge Anchor Zinc Plated
CONFAST 3/4″ x 5-1/2″ wedge anchors are engineered for durability in dry environments, focusing on reliable performance when anchoring to concrete. The kit emphasizes robust construction that tolerates everyday use in concrete-only applications. Each anchor package includes the required nut and washer, simplifying installation and ensuring proper hardware compatibility with the anchor body.
For best results, match the drill bit diameter to the anchor diameter and avoid base materials that are not solid concrete. These anchors are well-suited for securing equipment, brackets, or supports in concrete slabs and walls where weather exposure is minimal and long-term stability is essential.
3/4″ x 8-1/2″ Wedge Anchors
These heavy-duty wedge anchors from SURGE BUILDING PRODUCTS offer an extended 8-1/2″ length for deeper embedment in concrete. The zinc-plated carbon steel construction provides rust protection for indoor, dry environments, supporting reliable, high-load installations. The installation process remains simple due to the one-size drilling guidance aligned with the bolt diameter, promoting a clean and secure anchor every time.
Horiznext 3/4″ x 6-1/4″ Wedge Anchor
Horiznext provides a 3/4″ diameter wedge anchor with a 6-1/4″ length, designed for concrete and cement mounting. Carbon steel construction with zinc plating offers dependable corrosion resistance for indoor uses. The set includes ten pieces, which is convenient for standard projects requiring multiple anchors, such as mounting guard rails, frames, or heavy fixtures in a workshop or warehouse.
Shimeyao 10 Pack 3/4” x 7” Wedge Anchors
Shimeyao’s 3/4″ x 7″ wedge anchors deliver a robust carbon steel core with zinc plating for rust resistance. The 7-inch length enables deeper embedding, suitable for heavy-duty mounting in concrete.

SONIGEKO offers a 3/4″ diameter wedge anchor with a 6-1/4″ length and a carbon steel body featuring anti-rust properties. The anchors are designed for straightforward installation in concrete, with an all-thread design that accommodates a range of fixings. The kit emphasizes ease of use: prepare a hole matching the anchor diameter, insert, then tighten to secure. This makes the anchors suitable for mounting machinery, supports, or heavy fixtures in concrete environments.
Buying Guide: Key Purchase Considerations For 3/4 Inch Concrete Anchors
When choosing 3/4″ wedge anchors, consider the following factors to align with project needs and long-term performance:
- Material and corrosion resistance: Look for carbon steel with zinc plating for indoor dry environments, or consider stainless variants for exposure to moisture.
- Anchor length: Deeper embedment yields higher pull-out resistance. Match length to concrete thickness and the fixture’s load requirements.
- Concrete type and base material: Solid concrete and fully grouted blocks offer stronger holds. Avoid block or brick bases unless the product specifies compatibility.
- Drill bit size and installation: Use the same diameter as the anchor. Ensure clean holes free of debris to maximize grip and reduce bolt rotation during tightening.
- Included hardware: Some anchors include nuts and washers—verify what’s included to ensure a complete install kit without extra shopping.
- Quantity per package: Boxes of 10 or 20 are common; plan for future replacements or additional fixtures in the same project.
- Load and safety requirements: For structural or high-load applications, review manufacturer load ratings and local building codes before installation.
Practical installation tips include ensuring the hole depth matches anchor length, using compatible drill bits, and thoroughly cleaning the hole with compressed air to remove dust before insertion. Always use the correct wrench size when tightening to avoid over-torquing, which can damage the anchor or concrete surface.
