5/8 in x 5 in Concrete Anchors 25 Pack - Heavy Duty Wedge Bolts

In this review the 5/8 in x 5 in Concrete Anchors 25 Pack is evaluated for contractors, remodelers and serious DIYers who need reliable fasteners for solid concrete. The bottom line: these wedge anchors deliver predictable holding power and corrosion resistance in a simple, ready-to-install package, making them a practical choice when strength and repeatable performance matter. The reviewer found the assembled nut and washer, zinc plating and clear embedment guidance to be the most useful features for on-site efficiency.

Key Features

• Diameter and length: The 5/8 in diameter and 5 in length provide beefy engagement for medium to heavy loads in solid concrete.
• Preassembled convenience: Each anchor comes with a nut and washer assembled so installers save time and reduce handling on the job.
• Zinc plated carbon steel: The carbon steel construction with zinc plating helps resist surface rust for longer outdoor and indoor use.
• High pull-out capacity: A tested pull out load of 8360 lbf gives confidence when anchoring structural elements or heavy equipment.
• Clear embedment and thread length: Minimum embedment of 2-3/4 in and 2-7/8 in of thread length help ensure installers achieve rated holding values when installed per instructions.

Who It's For

These wedge anchors are best for professionals and experienced DIYers who work with solid concrete and need a repeatable, high-strength anchor for mounting machinery, structural connections, railings, or heavy fixtures. The 25-piece pack suits small crews or single projects where supply consistency matters.

They are not appropriate for hollow block, brick or softer masonry; anyone working primarily in those materials should select anchors designed for hollow substrates. Novice users should follow embedment and hole sizing instructions closely to avoid underperformance.
