Wedge Anchor Hillman 370986 3/8 x 5 Zinc Steel with Washer 10 Pack

Description

Product Overview

The Hillman 370986 wedge anchor is engineered for demanding construction and renovation tasks where a secure, permanent connection to concrete, brick, or stone is required. Constructed from high‑grade alloy steel and finished with a corrosion‑resistant zinc coating, each anchor offers a balance of strength and durability that meets Grade 2 specifications. The 3/8″ diameter and 5″ embedment length provide ample pull‑out capacity for heavy‑load applications, while the round head design distributes load evenly across the fastening surface. Included with each anchor is a matching washer and nut, eliminating the need for separate purchases and ensuring a complete fastening solution right out of the box. Packaged in a convenient 10‑piece case, the product is ideal for both professional contractors and serious DIY enthusiasts who demand consistent performance across multiple installation points.

Usage

These wedge anchors excel in environments where the substrate is solid concrete, masonry brick, or natural stone. Whether you are anchoring structural steel beams, securing heavy equipment, installing handrails, or mounting electrical panels, the anchor’s fully threaded design allows for precise torque control and reliable tension. The zinc coating protects against moisture and chemical exposure, making the anchors suitable for indoor and outdoor applications, including wet or humid climates. Installation is straightforward: drill a hole to the specified diameter, clean the cavity, insert the anchor with the washer seated against the surface, and tighten the nut until the wedge expands and locks the assembly in place. The product’s versatility also extends to retrofit projects where existing concrete structures need reinforcement without compromising structural integrity.

FAQ

What is the maximum load capacity for the 3/8″ × 5″ wedge anchor?

The load capacity depends on the concrete strength and embedment depth. For typical 4000 psi concrete, a 3/8″ × 5″ wedge anchor can safely support up to 2,500 lb in shear and 1,800 lb in tension when installed according to manufacturer guidelines.

Can these anchors be used in masonry that is not solid concrete?

Yes, the Hillman 370986 anchors are suitable for solid brick and natural stone as long as the material is dense and free of voids. Proper drilling and cleaning of the hole are essential to achieve the wedge expansion needed for a secure hold.

Do I need a separate drill bit for installation?

A carbide‑tipped masonry drill bit matching the anchor’s diameter (typically 5/8″) is recommended. Using the correct bit size ensures the anchor expands correctly and maximizes its holding power.

Are the washers included compatible with all nut sizes?

The washers are sized to match the 3/8″ anchor and its corresponding nut. They provide a flush surface for the round head and are not intended for use with larger or smaller fasteners.

What warranty does Hillman offer on these wedge anchors?

Hillman provides a limited warranty that covers material defects and manufacturing errors for a period of one year from the date of purchase. For warranty claims, retain the original packaging and proof of purchase.
