TIMCO Metal Construction Stitching Screws – For Sheet to Sheet – Hex – EPDM Washer – Self-Drilling – Exterior – Silver Organic

Self-Drilling Stitching Screws for Secure Sheet-to-Sheet Fixing

TIMCO Sheet-to-Sheet Self-Drilling Stitching Screws are specifically designed for fastening overlapping metal sheets together without the need for pre-drilling. The self-drilling point quickly penetrates both sheets, while the hex head allows high torque application for a secure, vibration-resistant hold. An integrated EPDM washer forms a watertight seal, protecting against leaks in exterior applications. The silver organic coating delivers outstanding corrosion resistance, making them ideal for roofing, cladding, and other outdoor metal-to-metal connections.
