Overview

The NSI Industries RD4300 Multi-Purpose Anchor (SKU: RD4300) is a versatile zinc-plated anchor designed for secure fastening in concrete, brick, cinder block, and thin-wall applications. With a 3-inch length and 1-1/4-inch minimum embedment depth, this anchor provides reliable load-bearing performance in medium-duty installations. The mushroom head design ensures flush mounting, while the 1/4-inch drill size and 5/16-inch clearance hole accommodate standard fasteners. Supplied in a 100-piece pack, the RD4300 is ideal for bulk purchases in construction, electrical, HVAC, and general contracting projects. Its zinc-plated finish offers corrosion resistance for indoor and outdoor use, making it a cost-effective solution for professionals requiring consistent, repeatable results. Compatible with standard 1/4-inch bolts or screws, this anchor simplifies installation while maintaining structural integrity in masonry and concrete substrates. The RD4300 meets industry standards for medium-duty anchoring, providing a balance of strength, versatility, and affordability in a single product. Designed for ease of use, the RD4300 requires a 1/4-inch drill bit for installation, ensuring compatibility with common tools and hardware. The 5/16-inch clearance hole size allows for proper fitment of bolts or screws without excessive play, reducing the risk of misalignment during assembly. With a minimum embedment depth of 1-1/4 inches, the anchor achieves optimal holding power in solid substrates while minimizing material waste. The mushroom head design prevents over-tightening and provides a clean, finished appearance in exposed applications. Each 100-piece pack ensures sufficient quantity for large-scale projects or frequent use in professional settings. The zinc plating enhances durability in harsh environments, resisting rust and corrosion to extend the anchor’s service life. Suitable for both temporary and permanent installations, the RD4300 delivers dependable performance across a wide range of medium-duty fastening needs.
