5/16″ x 2-1/2″ Hex Sleeve Anchor Zinc Plated CONFAST Steel (100 pcs)

Description

Product Overview

The CONFAST 5/16″ x 2-1/2″ hex sleeve anchor is engineered for demanding fastening tasks. Its zinc‑plated finish provides corrosion resistance while the all‑steel construction delivers the strength required for heavy‑duty applications. Packaged in a compact 6.69 x 4.72 x 3.54‑inch box weighing 6.15 pounds, each box contains 100 pre‑assembled anchors, eliminating the need for separate components and reducing installation time.

Designed with a 360‑degree expansion mechanism, the anchor expands uniformly as the bolt is tightened, ensuring consistent holding values across a wide range of base materials. The anchor size matches the recommended hole size, simplifying the drilling process and guaranteeing optimal performance. This pre‑assembled design means installers can move directly from drilling to placement without additional assembly steps.

Manufactured by CONFAST, a reputable brand in industrial fasteners, the anchor undergoes rigorous quality testing to meet industry standards. The zinc plating not only protects against rust but also enhances the anchor’s lifespan in harsh environments. Heavy‑duty all‑steel parts are forged to resist deformation under load, making the product suitable for structural support, equipment mounting, and other critical applications.

With a best‑seller rank of #13 in the Sleeve Anchors category and a 4.7‑star rating from 29 verified customers, the anchor has proven its reliability in real‑world projects. Whether you are securing a concrete post, attaching a steel bracket to brick, or anchoring a heavy machine to a solid block, this product delivers the confidence of a secure, long‑lasting connection.

Usage

The anchor is versatile enough to be installed in a wide variety of masonry substrates, including solid concrete, brick, block, and stone. For optimal performance, drill a hole matching the anchor’s diameter, clean out debris, insert the pre‑assembled anchor, and tighten the bolt to the specified torque. The 360‑degree expansion ensures the anchor grips the surrounding material evenly, providing a stable and secure hold.

Professional contractors and seasoned DIY enthusiasts alike appreciate the simplicity of the pre‑assembled design. No additional washers or nuts are required, which reduces the number of parts to manage on site. The zinc‑plated finish also tolerates exposure to moisture and chemicals, making it suitable for outdoor installations, industrial facilities, and residential renovation projects.

When working in extreme temperature conditions or environments with high humidity, the anchor’s all‑steel composition and protective coating maintain structural integrity. It is ideal for applications such as mounting heavy equipment, securing structural steel members, anchoring electrical panels, and installing safety railings. The product’s consistent performance across diverse conditions helps users meet code requirements and project specifications.
