The Daggerz™ 12-24 x 2" Star Flat Head Self Drill Screws with Wings SD4CTWWST1220 are engineered for demanding wood-to-metal fastening applications. Featuring a #4 self-drilling point and innovative wing design, these screws eliminate pre-drilling while preventing wood jacking during installation. The wings ream out the wood before breaking away upon contact with steel, allowing the threads to engage securely. Manufactured from C1022 low carbon steel, the screws feature a T-27 Star drive for superior torque transfer and Dagger Ultra-Guard Coating™ that provides up to 1,000 hours of salt spray resistance and compatibility with ACQ-treated lumber. Each carton contains 2,000 screws.
