Tapcon Scots 1/4 in x 1-3/4 in Stainless Steel Concrete Anchor Screws

In this review the Tapcon Scots 1/4 in x 1-3/4 in Concrete Anchor Screws are assessed for tradespeople and serious DIYers who need reliable masonry fasteners. The bottom line: these anchors stand out for their thread design and a moisture-sealing washer that help prevent water intrusion when fastening into concrete, block or brick. The review focuses on real-world usability, corrosion resistance claims, and whether the package contents and build quality match expectations for a 100 pack that includes a drill bit.

Key Features

• Advanced Threadform Technology: The thread profile is engineered to cut into concrete and masonry for a secure, vibration-resistant hold that reduces pullout risk.
• Rubber EPDM Sealing Washer: The integrated washer helps lock out moisture at the head, which is useful where weather exposure or indoor moisture control matters.
• 300 Series Stainless Steel Head: The stainless steel head provides corrosion resistance at the fastening point and improves durability in damp conditions.
• Drill Bit Included: Including a drill bit in the pack makes installation easier on site and ensures the correct pilot hole size is available.
• Suitable for Multiple Masonry Types: Designed to work with concrete, block and brick, offering flexibility for mixed masonry projects.

Who It's For

The Tapcon Scots anchors are best for contractors, masons and advanced DIYers who frequently secure fixtures to concrete, brick or block and want the convenience of a 100 pack with a drill bit included. They suit exterior and interior applications where a sealed head is desirable to help prevent moisture entry.

Those who should look elsewhere include users who need specialty coatings or higher-grade stainless steel for marine environments, or anyone requiring non-threaded expansion anchors; this product is specifically a masonry screw with a sealing washer and 300 series head.

Pros & Cons

Pros

• Advanced threadform provides strong engagement in concrete and other masonry for reliable holding power.
• EPDM sealing washer helps keep moisture out of the building interior where the fastener passes through a fixture.
• Pack of 100 with a drill bit included is convenient for jobs that need multiple anchors without sourcing separate accessories.

Cons

• Some buyers question whether every screw is full stainless steel, so those needing absolute proof of material grade may want laboratory-verified hardware or higher alloy grades.
