Tapcon 24292 Hex-Washer-Head Large Diameter Concrete Anchor, 5/16" x 2-1/4'', 15-ct Deliver unmatched strength and reliability in masonry applications with the Buildex Tapcon 24292 Concrete Screw Anchor, a high-performance fastener engineered for secure attachment in concrete, brick, and hollow block. Packaged in a 15-piece clamshell pack, these 5/16-inch diameter, 2-inch long hex-drive screws offer professional-grade holding power for demanding structural and construction projects. Designed with a one-piece construction, they require no assembly and eliminate the need for torque-down, streamlining installation and ensuring consistent performance. Crafted from durable steel with a coarse high/low thread design, these screws create their own internal threads as they are driven into pre-drilled holes, delivering a tight, secure fit in both solid and hollow substrates. The high/low thread pattern enhances grip in brittle base materials, reducing the risk of pull-out and improving load capacity. The hex head (5/16" drive) allows for high-torque installation using standard hex bits, making it ideal for use with impact drivers and torque-controlled tools. The Tapcon 24292 features the innovative Climaseal blue coating?a zinc-based plating with enhanced corrosion resistance that protects against moisture, humidity, and harsh environmental conditions. This blue finish provides long-lasting durability for both interior and exterior applications, including areas exposed to weather, coastal environments, or high-moisture settings. The metallic appearance with blue plating family ensures visual identification of the corrosion-resistant treatment. With a minimum embedment depth of 1-3/4 inches, these screws are ideal for attaching critical components such as sill plates, handrails, window framing, furring strips, and electrical equipment to concrete and masonry surfaces. They are approved for use in cracked concrete and seismic zones, meeting rigorous industry standards for structural integrity and safety. An ANSI-standard drill bit is required for proper hole preparation to ensure optimal fit and performance. Weighing 0.600 lb per pack and measuring 5.50 inches in width, 1.38 inches in height, and 2 inches in length under the head, these anchors are compact and easy to store on-site. The SAE measurement standard ensures compatibility with standard U.S. tools and construction practices.
