Uncover the full potential of this product

Daggerz SDZ14034 14 x 3/4" Hex Washer Head Self-Drilling Screws are engineered for high-performance, heavy-duty industrial fastening. Manufactured by International Fasteners, Inc., these commercial-grade fasteners eliminate the need for separate hole drilling and tapping, significantly cutting down installation time. Each screw is equipped with a razor-sharp #3 self-drilling point that effortlessly pierces through tough, multi-layered metal sheets. The integrated 3/8" hex washer head ensures optimal torque delivery while the wide built-in flange distributes clamping pressure evenly to prevent surface distortion. Available in standard zinc-plated carbon steel or high-durability Dagger-Guard exterior coatings, these screws deliver long-lasting structural integrity. Sold in convenient, high-volume cartons of 3,500 pieces, they provide an efficient and cost-effective fastening solution for large-scale job sites.
