Hillman 370986 Wedge Anchor 3/8x5 in Zinc-plated 10ct

Product Description

The HILLMAN 370986 is a zinc-plated steel wedge anchor designed for secure fastening into concrete, stone, brick, and block substrates. Each anchor measures 3/8 inch in diameter by 5 inches in length and uses a mechanical wedge-expansion design that locks into the base material as the nut is tightened. This fastener is suited for medium to heavy-duty structural and fixture-mounting applications. Sold in a box of 10, it is a standard choice for contractors, masons, and general tradespeople who need reliable anchored connections in solid masonry and concrete.

This wedge anchor is used in a wide range of commercial and residential construction tasks, including securing equipment bases, structural supports, railings, brackets, and mechanical system components to concrete floors, walls, and foundations. The zinc-plated finish provides basic corrosion resistance for interior and protected exterior environments. The anchor requires a drilled hole matching the anchor diameter, and exact hole depth is not critical, simplifying layout and installation on the job.

Key Features

• 3/8 inch diameter by 5 inch length for medium to heavy-duty load applications
• Zinc-plated steel construction for corrosion resistance in interior and sheltered environments
• Wedge-expansion design locks mechanically as the nut is torqued down
• Compatible with concrete, stone, brick, and block base materials
• Drill hole same diameter as anchor — exact hole depth not required
• Sold in a box of 10 for single-job or multi-point installations

Compatibility

Designed as a standard 3/8 inch wedge anchor for use in solid concrete, stone, brick, and block substrates where a through-bolt or expansion anchor connection is required.

Installation Notes

Installation is performed by general contractors, masons, or qualified tradespeople using a hammer drill and carbide-tipped bit sized to match the 3/8 inch anchor diameter. The hole should be blown clear of debris before inserting the anchor. The nut should be tightened until the anchor is mechanically set — do not over-torque, as this can crack the base material near the hole. Follow applicable building codes and anchor manufacturer load tables for structural applications.
