Hex Multi-Drive Concrete Masonry Screws — 200-Pack Tapcon-Style Tapscrews That Hold Where Others Strip Out
Anyone who has wrestled with a stripped anchor or a crumbling pre-drilled hole knows how frustrating masonry fastening can be. Whether you're a contractor running conduit, a remodeler attaching furring strips, or a homeowner mounting shelving in a garage or basement, you need a concrete screw that threads cleanly, seats flush, and stays put. These hex multi-drive masonry tapscrews are built for exactly that job.
This 200-piece pack contains blue-coated hex multi-drive concrete tapscrews in the Tapcon style — the industry-standard format for direct masonry anchoring without expansion inserts. The blue corrosion-resistant coating provides protection against moisture and oxidation. The hex multi-drive head accepts both a hex socket and a slotted driver, giving you flexibility on the jobsite whether you're using an impact driver, drill, or manual screwdriver.
Typical applications include anchoring electrical conduit straps to poured concrete walls, fastening wood sill plates to concrete block foundations, securing shelf brackets and track systems in masonry garages, and attaching furring strips to brick or block for wall assemblies.
✅ Key Features of These Hex Multi-Drive Concrete Masonry Screws
- Blue Corrosion-Resistant Coating: The blue finish provides a protective barrier against moisture and oxidation, making these tapscrews suitable for interior masonry and light outdoor concrete screw applications.
- Hex Multi-Drive Head: Accepts both a hex socket and a slotted driver — drive with a standard impact driver, drill, or manual screwdriver. No specialty bits required, no cam-out under torque.
- Direct-Thread Tapcon-Style Design: Hi-lo thread geometry cuts directly into pre-drilled concrete, brick, or block without expansion inserts, reducing installation steps and minimizing substrate cracking.
- 200-Piece Bulk Pack: A job-ready quantity for contractors and serious DIYers — enough fasteners to complete multi-phase projects including conduit runs, furring strip layouts, or full wall assemblies without mid-job restocking.
- Multiple Length Options: Available in multiple lengths to match your embedment depth requirements. Minimum recommended embedment is generally 1" (25mm) into the base material — select the length that clears your fixture thickness plus embedment.
- Impact Driver Compatible: The hex shank seats securely in standard 1/4" hex chucks for fast driving with a cordless impact driver — no slipping, no cam-out under high torque.
🎯 Who Is This For?
Mount shelving, brackets, and storage systems directly into concrete garage walls or basement floors — no expansion anchors or specialty tools required.
Run conduit straps, secure junction boxes, and fasten furring strips to masonry walls with a bulk pack that keeps the job moving without restocking runs.
Attach sill plates to concrete block foundations, anchor wall assemblies, and fasten track systems in masonry garages — the multi-drive head works with any standard impact driver or drill.

❓ Frequently Asked Questions
How do I choose the right length of concrete screw for my project?
A general rule is that the screw should embed at least 1 inch (25mm) into the base material. Measure the thickness of the material being fastened, then add your minimum embedment depth. For example, fastening a 1/2" bracket into concrete typically calls for a screw around 1-1/4" to 1-3/4" long. Select the variant length that matches your embedment requirement.
What diameter are these concrete screws?
These are typically 3/16" (approximately 4.8mm) hex multi-drive masonry tapscrews — the most common diameter for light-to-medium duty concrete anchoring. Please check the variant options above to confirm the exact diameter included in this 200-pack.
What drill bit size do I need for these masonry screws?
Concrete screws generally require a carbide-tipped masonry drill bit sized to match the screw diameter. For 3/16" screws, a 5/32" (4mm) carbide masonry bit is typically used. Always drill to the required embedment depth plus a small clearance, and blow out dust before driving the screw.
Can these screws be used outdoors or in wet conditions?
The blue corrosion-resistant coating provides general protection against moisture and light outdoor exposure. For consistently wet environments, submerged applications, or coastal climates, a stainless steel or hot-dip galvanized fastener is generally recommended for long-term corrosion resistance.
What base materials are these concrete screws compatible with?
These hex multi-drive masonry tapscrews are designed for use in concrete, brick, block, and mortar. They are not intended for use in wood, drywall, or metal without a suitable masonry substrate. Always pre-drill with a carbide masonry bit before installation.
What is the load capacity of these masonry tapscrews?
Load capacity varies by screw diameter, length, embedment depth, and the strength of the base material. Concrete screws of this type typically handle light-to-medium duty loads such as conduit straps, furring strips, electrical boxes, and shelf brackets. For structural or heavy-load applications, consult a load table or engineer for the specific screw size and concrete strength.
Can these screws be removed and reused after installation?
Concrete tapscrews can generally be removed by reversing the drive direction, but reuse is not recommended. Repeated removal and reinstallation degrades the thread engagement in the base material, reducing holding strength. For applications requiring frequent removal, consider a sleeve anchor or drop-in anchor instead.
