Hex Head Sleeve Anchor by Hillman 3/8 x 1-7/8 Zinc Plated 50 Pack

Description

Product Overview

The Hillman 370800 Hex Head Sleeve Anchor is engineered from high‑grade alloy steel and finished with a zinc plating that resists corrosion in demanding environments. Each anchor measures 3/8 inch in diameter and extends 1‑7/8 inches, providing a deep‑set grip that distributes load across a broad surface area. The hex head design matches standard socket‑wrench sizes, allowing installers to achieve precise torque without slipping. Packaged in a convenient 50‑piece bundle, this product meets the needs of professional contractors, maintenance crews, and DIY enthusiasts who require reliable fastening solutions for heavy‑duty applications such as door frames, window installations, shelving units, and structural supports. The anchors are classified as Grade 2, meeting industry standards for tensile strength and shear resistance, ensuring long‑term performance even under cyclic loading.

Usage

These sleeve anchors excel in concrete, masonry, and solid‑stone substrates where a secure, permanent connection is essential. Prior to installation, a pilot hole must be drilled to the recommended diameter, allowing the anchor to expand uniformly as the bolt is tightened. The expansion mechanism creates a mechanical lock that resists pull‑out forces, making the anchor ideal for mounting heavy fixtures such as electrical panels, HVAC equipment, and commercial shelving. Because the zinc‑plated finish offers moderate corrosion protection, the anchors are suitable for indoor and semi‑outdoor environments, including garage workshops, retail displays, and light‑exposure exterior walls. Users should select the appropriate drill size based on the anchor diameter and follow the manufacturer’s torque specifications to achieve optimal holding strength.

FAQ

Do I need a pilot hole before installing these anchors?

Yes. A correctly sized pilot hole is essential for the anchor to expand properly and achieve its rated holding strength. Refer to the product packaging for the recommended drill diameter.

Can these anchors be used outdoors?

The zinc‑plated finish offers moderate corrosion protection, making the anchors suitable for indoor and semi‑outdoor applications where exposure to moisture is limited. For fully exposed exterior conditions, consider a stainless‑steel or hot‑dip galvanized alternative.

What torque setting should I use when tightening the bolt?

Follow the manufacturer’s torque specifications, typically ranging from 30 to 45 ft‑lb for a 3/8″ diameter anchor. Using a calibrated torque wrench ensures consistent performance and prevents over‑tightening.

Are these anchors compatible with all types of concrete?

They are designed for standard concrete mixes and masonry blocks. For high‑strength or specialty concretes, verify compatibility with the supplier or conduct a pull‑out test to confirm adequate holding capacity.

How many anchors come in each package?

Each package contains 50 individually packaged hex head sleeve anchors, providing ample quantity for large projects or multiple installations.
