Hilti 2141809 Stud Anchor KB-TZ 3/8×3 – Heavy Duty Concrete Fastener

Description

Product Overview

The Hilti 2141809 stud anchor, part of the KB‑TZ series, is engineered for demanding concrete applications where strength, reliability, and ease of installation are paramount. Constructed from high‑grade steel that meets UL certification standards, this anchor offers a robust connection that resists corrosion and maintains structural integrity over time. With a cutting diameter of 3/8 inches and an assembled diameter of the same size, the anchor fits precisely into pre‑drilled holes, delivering a secure hold without the need for additional components. Weighing only 2.99 pounds, the anchor is lightweight enough for rapid deployment yet strong enough to support heavy loads in industrial settings. The product is supplied as a bare‑tool unit, meaning no batteries or auxiliary parts are required, simplifying inventory management and reducing overall cost. Its design incorporates a smooth shank that minimizes friction during insertion, while the threaded end provides a firm grip that distributes load evenly across the concrete substrate. This combination of material quality, precise engineering, and user‑friendly features makes the Hilti 2141809 a preferred choice for contractors, engineers, and maintenance professionals who demand consistent performance on every job site.

Usage

Designed specifically for concrete, the Hilti 2141809 stud anchor excels in a variety of real‑world environments. It is ideal for anchoring heavy equipment, structural steel, and mechanical systems in commercial construction, industrial facilities, and infrastructure projects. Whether you are installing electrical conduit supports, mounting machinery bases, or securing safety railings, this anchor provides the confidence that the connection will hold under dynamic loads and harsh conditions. The anchor’s 3/8‑inch diameter makes it compatible with standard concrete drill bits, allowing for quick preparation of the installation site. Its UL certification assures compliance with safety regulations, making it suitable for projects that require documented adherence to industry standards. The anchor can also be used in retrofit applications where existing concrete structures need reinforcement without extensive demolition. Its compact profile enables installation in confined spaces, such as ceiling voids, wall cavities, and tight mechanical rooms, where larger fasteners would be impractical. By delivering a reliable, load‑bearing solution, the Hilti 2141809 helps reduce downtime, lower labor costs, and improve overall project efficiency.
