- Precise 1/4 in. diameter and 4 in. length: Designed for solid concrete and masonry, providing a strong anchor with ample thread engagement.
- Slotted drive with hex washer head: Combines a traditional slotted bit with a robust hex washer head that seats flush, spreads load, and resists cam-out for steady driving.
- High/Low thread design: The dual-thread pattern increases bite and grip, delivering reliable pull-out strength while reducing driving torque.
- Climaseal finish in blue: A moisture-resistant coating that enhances corrosion resistance for durable use in damp or outdoor environments.
- Steel construction: Solid steel fasteners engineered to withstand everyday mounting stresses in masonry projects.
- Complete, ready-to-use package: 25 screws per clamshell with a driver bit included, so you have what you need to complete your install without hunting for accessories.
- Indoor and outdoor versatility: Suitable for a wide range of applications—from garages and basements to exterior facades and outdoor structures. Ideal use cases and scenarios
- Mounting wall brackets, shelving, or electrical fixtures to poured concrete walls or masonry surfaces.
- Securing metal supports or wood-to-concrete connections where a strong, flush-seated fastener is required.
- Attaching base plates, conduit hangers, or outdoor fixtures where corrosion resistance and long-length engagement matter.
- Renovation projects that demand reliable anchors in solid masonry without resorting to traditional lag screws or nails. Why this concrete screw is a smart choice
- Targeted design for masonry: Tapcon’s concrete screws are engineered to thread directly into concrete, creating a dependable anchor with predictable performance.
- Quick, confident installation: The high/low thread pattern reduces resistance, so you can drive to snug without over-torquing or stripping the screw.
- Clear visibility and durability: The blue Climaseal finish provides a corrosion barrier, helping your installation look and perform well over time in varied environments. Practical installation tips
- Prepare the surface: Clean the drilling area to remove dust and debris for maximum thread contact.
- Use the right pilot hole: Follow standard manufacturer guidelines for pilot hole sizing to suit the screw diameter and concrete hardness.
- Drive with control: Start at a steady pace, allowing the high/low threads to bite, then finish with consistent torque to seating without over-tightening.
- Verify load requirements: For any high-load application, confirm that the 4 in. length provides sufficient embedment depth in the chosen concrete. What you get
