Tapcon 28585 Star Drive Bugle Head Concrete Anchors 1/4×2-3/4 150 Box

Description

Product Overview

Tapcon 28585 delivers a premium Star Drive Bugle Head design that combines precision engineering with rugged durability. Each anchor is forged from hardened steel, heat‑treated to meet ASTM standards for tensile strength and shear resistance. The blue Climaseal coating provides a barrier against moisture, chemicals, and atmospheric corrosion, extending the life of the fastener in harsh environments. The 1/4‑in. diameter and 2‑3/4‑in. length are optimized for a wide range of masonry applications, from residential remodels to commercial construction projects. The bugle head geometry distributes load evenly, reducing stress on the surrounding material and improving pull‑out resistance.

Usage

These anchors excel in any masonry‑based substrate, including poured concrete, concrete block, brick, and stone. Installers can confidently use them to attach sill plates, electrical conduit brackets, HVAC equipment, and 2 ft × 4 ft fixtures such as shelving or wall panels. The star‑shaped drive eliminates bit slip, allowing for smooth, consistent torque application even in tight spaces. For best results, pre‑drill a pilot hole using a 5/32‑in. carbide bit, clean the hole of dust, and insert the anchor until the head sits flush with the surface. The anchor’s self‑tapping chisel edges cut threads into the substrate, creating a secure hold without the need for additional adhesives.

FAQ

What size pilot hole should I use for these anchors?

For the 1/4‑in. diameter Tapcon 28585, a 5/32‑in. carbide drill bit is recommended. This size creates the optimal balance between thread engagement and ease of insertion.

Can these anchors be used in outdoor applications?

Yes. The blue Climaseal coating is specifically engineered to resist moisture, UV exposure, and salt spray, making the anchors suitable for exterior installations such as fence posts, deck footings, and façade anchoring.

Do I need to apply any adhesive or epoxy when using these anchors?

No adhesive is required for standard load applications. The self‑tapping design provides reliable mechanical retention. For critical load or seismic requirements, a compatible construction epoxy can be used in addition to the anchor.

What is the warranty coverage for Tapcon concrete anchors?

Tapcon offers a limited warranty against material defects for the life of the product when used according to the manufacturer’s installation guidelines. Contact our support team for specific warranty claim procedures.

Are these anchors compatible with impact drivers?

Yes. The star‑shaped drive is designed to work with impact drivers, providing high torque transfer while minimizing the risk of cam‑out. Use a torque‑controlled setting to avoid over‑driving the anchor.
