Concrete Screws Krysay 35 Piece Kit with Blue Hex Head 1/4×2-3/4 in

Description

Product Overview

The Krysay 35‑piece concrete screw kit is engineered for reliability and ease of use across a wide range of construction and renovation tasks. Every screw is crafted from high‑grade 1022A carbon steel, heat‑treated for superior strength, and finished with a blue rust‑resistant coating that endures harsh environments, including exposure to moisture and chemicals. The hex‑head design, paired with a precision‑cut diamond point, enables rapid penetration without the need for separate anchors, saving time and reducing material costs.

Dimensions of the kit are compact—6 × 4 × 0.66 inches—making storage simple, while the total weight of 15 ounces ensures the package is lightweight yet robust. The included drill bit matches the 1/4‑inch diameter of the screws, guaranteeing optimal thread engagement and minimizing wear on both the bit and the fastener. This comprehensive set is ideal for professionals who demand consistency and for DIY enthusiasts seeking a dependable solution for anchoring heavy objects.

Usage

These masonry screws excel in concrete, brick, cinderblock, and stone applications. Whether you are installing a heavy-duty shelving system in a garage, mounting electrical boxes on a concrete wall, or securing outdoor lighting fixtures, the Krysay kit delivers a secure hold that meets building code requirements. The self‑tapping design eliminates the need for pre‑drilled pilot holes, allowing you to work efficiently in tight spaces such as basements, patios, and commercial facilities.

Because the screws are coated to resist hydrochloric acid corrosion for up to 1,000 hours, they are also suitable for environments with exposure to chemicals, such as industrial workshops or areas near swimming pools. The varied lengths—from 1/4 × 1‑1/4 in to 1/4 × 2‑3/4 in—provide flexibility for different material thicknesses, ensuring a firm grip regardless of the substrate.
