CONFAST 3/8″ Threaded Rod Anchor for Concrete 1/4″ x 1-1/2″ Box of 25

Description

Product Overview

CONFAST’s 3/8″ threaded rod anchor is engineered for demanding concrete applications where strength and reliability are non‑negotiable. Constructed from high‑grade steel, the rod offers a corrosion‑resistant finish that maintains structural integrity even in harsh industrial environments. The anchor’s dimensions—0.25 × 0.38 × 0.38 inches and a weight of 1.21 lb per unit—provide a compact profile while delivering a load‑bearing capacity that exceeds typical stud anchors in its class. Each rod is sized at 1/4″ × 1‑1/2″, a standard dimension that fits a wide range of fastening systems, allowing engineers and contractors to standardize on a single component for multiple projects. The product’s design incorporates a one‑piece construction that eliminates the need for additional washers or spacers, simplifying inventory management and reducing the chance of assembly errors on site.

The integrated special nut driver is machined to prevent shearing of the fastener during torque application, ensuring that the anchor remains securely seated without compromising the surrounding concrete. By requiring a pilot hole of precise diameter, the anchor achieves optimal grip, translating into consistent holding values across varied concrete mixes. The packaging of 25 units per box is optimized for bulk purchasing, offering cost efficiency for large‑scale installations while keeping handling lightweight for individual use. With a Best Sellers Rank of #4 in Stud Anchors and a 4.3‑star rating from 28 verified customers, the product demonstrates both market acceptance and user satisfaction, reinforcing its reputation as a dependable choice for vertical anchoring tasks.

Manufactured under CONFAST’s rigorous quality‑control program, each anchor undergoes dimensional verification, tensile testing, and corrosion resistance assessment before leaving the factory. The steel alloy conforms to ASTM A307 standards, guaranteeing that the anchor can withstand cyclic loading and dynamic forces typical in industrial settings. Environmental testing includes exposure to moisture, temperature fluctuations, and chemical agents commonly encountered in construction sites, ensuring long‑term performance. Documentation provided with each shipment includes material certification, load charts, and installation guidelines, empowering engineers to make informed decisions and maintain compliance with local building codes.

Usage

Designed for vertical anchoring in concrete, this rod anchor excels in applications such as structural steel connections, utility pole installations, and heavy‑duty equipment mounting. Its 1/4″ × 1‑1/2″ size makes it compatible with a broad spectrum of nuts, washers, and coupling devices, enabling seamless integration into existing fastening systems. The pilot‑hole requirement ensures that the anchor can be installed quickly using standard rotary drills, while the special nut driver reduces the risk of over‑torquing, protecting both the anchor and the surrounding concrete from damage.

Typical use cases include anchoring of HVAC units, fire‑suppression systems, and industrial machinery where vibration resistance and load stability are critical. The anchor’s corrosion‑resistant coating allows it to perform reliably in outdoor environments, coastal installations, and areas exposed to chemicals or de‑icing salts. Contractors appreciate the one‑piece design because it eliminates the need for additional components, reducing the chance of missing parts during assembly and speeding up the overall installation timeline.

For DIY enthusiasts, the anchor offers a straightforward installation process: drill the recommended pilot hole, insert the rod, and tighten the nut using the provided driver. The clear markings on the rod indicate the correct insertion depth, helping users achieve optimal embedment without guesswork. Whether you are retrofitting an existing structure or constructing a new facility, the anchor’s versatility and ease of use make it a practical solution for a wide range of fastening challenges.
