About this item

3/16" x 3‑1/4" Tapcon Slotted Concrete Screws – 100-Pack (Model 375290)

Engineered for strong, dependable fastening into masonry substrates, the Model 375290 slotted Tapcon‑type concrete screws provide robust holding power for concrete, brick, and block applications. These screws feature a precision‑cut thread design that allows them to tap their own threads as they are driven, creating a secure mechanical bond without the need for anchors or sleeves.

The blue Perma‑Seal‑type protective coating enhances corrosion resistance, making these anchors suitable for both indoor and outdoor installations as well as use with treated lumber. The slotted hex washer head design delivers exceptional driving stability, helping reduce stripping and improving installation consistency in tougher base materials.

This 100‑count contractor pack is ideal for repetitive fastening tasks and applications requiring longer anchor length, such as attaching thick fixtures, mounting hardware to deeper masonry surfaces, or securing framing components that must penetrate multiple layers before reaching the base material.

Key Features

  • Slotted hex washer head for improved drive control and secure seating against fixture surfaces.
  • High‑performance thread engineering allows the screw to tap directly into concrete, brick, or block without additional hardware.
  • Durable blue corrosion‑resistant coating enhances longevity in exterior and moisture‑exposed environments.
  • Suitable for use with treated lumber and approved under applicable building code standards.
  • Designed for use with compatible Tapper‑style masonry bits for optimal driving performance.
  • Strong holding values across multiple masonry base materials, suitable for medium‑duty structural and mechanical fastening.
