Heavy-Duty Blue Concrete Screws for Reliable Masonry & Brick Anchoring

Achieve professional-grade fastening with IMSCREWS 3/16 x 1-3/4 inch concrete screws. Designed for high-torque performance and long-lasting durability, these anchors are the industry standard for securing wood, metal, and plastic fixtures to hard masonry surfaces.

Can these be used on brick?
Yes, these screws are specifically engineered for superior performance in brick, concrete, hollow block, and stucco. The specialized High-Low thread design cuts deeply into the masonry material, providing far more gripping power than standard smooth-thread anchors.

Are they rust resistant and weatherproof?
Absolutely. Each screw is protected by a high-performance blue coating that has been tested for corrosion resistance. These fasteners are weatherproof and suitable for both interior and exterior applications, including wet or humid environments.

Do they come with a storage case?
This 50-pack is provided in cost-effective bulk packaging to ensure you get the best value for your large DIY or contractor projects. Please note that this package contains the screws only; a 5/32 inch masonry drill bit is required for installation and is not included.

Installation Guide for Best Results:
1. Pre-Drilling: You must use a 5/32" masonry drill bit to create a pilot hole.
2. Depth Matters: Ensure the hole is at least 1/4" deeper than the screw will be driven. This provides a reservoir for concrete dust and prevents the screw from bottoming out and breaking.
3. Dual Drive: Use a 1/4" hex nut driver or a flat-head screwdriver for a secure installation.
