Red Head LDT-3830 Large Diameter Tapcon 3/8″ x 3″ Anchor 50 Pack

Description

Product Overview

The ITW Red Head LDT-3830 Tapcon anchor is engineered for demanding concrete applications where a secure, permanent hold is essential. Measuring 3 inches in overall length with a 0.38‑inch (3/8‑inch) cutting diameter, each anchor is forged from hardened carbon steel and finished with a zinc‑plated coating that resists corrosion in harsh environments. The flanged hex washer head features anti‑rotation serrations, providing a stable, vibration‑resistant connection that simplifies installation and reduces the risk of loosening over time. The anchor is stamped with a length identification code for quick verification on the job site, and it is compatible with standard drill bits, eliminating the need for specialty tools.

Usage

Designed specifically for concrete, the LDT-3830 excels in a variety of construction and renovation projects. It is ideal for securing structural steel members, attaching electrical conduit, mounting heavy‑duty equipment, and anchoring fixtures such as handrails, shelving, and signage. The anchor’s self‑tapping capability allows it to cut its own threads directly into pre‑drilled holes, delivering a strong bond without the need for additional inserts. Whether you are a contractor working on commercial buildings, a facilities manager retrofitting an industrial plant, or a DIY enthusiast tackling a home improvement project, this anchor provides the confidence of a load‑bearing connection that meets code requirements.

FAQ

What drill size should I use for the LDT-3830?

Use a standard 5/16‑inch (8 mm) masonry drill bit to create the pilot hole. The anchor will then cut its own threads as it is driven in.

Can the anchor be used in masonry other than concrete?

Yes, the LDT‑3830 performs well in brick, block, and stone, provided the substrate is solid and the pilot hole is drilled to the recommended depth.

Is a pre‑drilled hole required?

Yes, a pilot hole must be drilled to the specified depth. The anchor’s cutting tip will then form threads as it is installed, eliminating the need for a separate insert.

What is the load capacity of this anchor?

When installed according to the manufacturer’s guidelines, the LDT‑3830 can achieve a tensile load capacity of approximately 1,500 lb and a shear capacity of about 1,200 lb, depending on concrete strength.

Does the product come with a warranty?

The anchor is sold without a warranty, but Red Head provides technical assistance and replacement options for any manufacturing defects identified within a reasonable timeframe.
