#8-18 x 3" Partial Thread Square Drive Trim Head Self-Drilling Screws Zinc CR3+ Plated 2,000ct | T3QZP

Strong-Point #8-18 x 3" Partial Thread Square Drive Trim Head Self-Drilling Screws Zinc CR3+ Plated

Strong-Point #8-18 x 3" Partial Thread Square Drive Trim Head Self-Drilling Screws are designed for attaching wood to metal. The trim head provides a clean, low-profile finish while the square drive reduces cam-out and improves driver engagement during installation. The partial thread design helps pull materials together and improve clamping force when fastening wood to steel framing. The #2 self-drilling point delivers fast, consistent drilling through steel thicknesses from .035" to .100". Zinc CR3+ plating provides corrosion protection by forming a protective barrier that helps prevent oxidation.
