3/8 in x 7 in Concrete Anchors 50 Pack - Heavy Duty Wedge Bolts

In this review of the 3/8 in x 7 in Concrete Anchors (50 Pack), the bottom line is simple: these wedge anchors are a solid choice for installers who need reliable holding power in solid concrete without fuss. The reviewer found they deliver consistent expansion grip, a useful 4 in of thread length for adjustments, and zinc plating that helps resist surface corrosion. For contractors, handymen, and homeowners mounting fixtures to poured concrete, the combination of a 50-piece count and a 3747 lbf pull out load makes them a practical, cost-effective option.

Key Features

• 3/8 in Diameter: Provides a balance of shear and pull-out strength suitable for common anchoring tasks in solid concrete.
• 7 in Length with 4 in Thread: Extra thread length makes it easier to attach flanges, plates, or brackets while maintaining proper embedment.
• Minimum Embedment 1-1/2 in: Clear embedment guidance ensures installers can achieve the published holding values when installed correctly.
• Zinc Plated Carbon Steel: Zinc finish reduces surface rust and adds durability for interior or exterior use where moderate corrosion resistance is required.
• Assembled with Nut and Washer: Ships ready to install so there is less preparation on site and faster installation cycles.
• Rated Pull Out Load 3747 lbf: High nominal pull-out rating gives confidence for medium-duty structural and mounting applications in solid concrete.

Who It's For

The anchors suit general contractors, remodelers, and serious DIYers who mount railings, machinery bases, shelving, and structural hardware into poured concrete. The 50-pack quantity is convenient for jobsite runs or multiple installations around a property.

They are not intended for use in hollow block, brick, or soft masonry; if the project involves those materials or requires stainless corrosion resistance for marine environments, a different anchor type or finish would be more appropriate.

Pros & Cons

Pros

• High pull-out capacity gives dependable holding strength for medium-duty fixtures.
