These #7 x 2-1/4 in. trim head Streaker screws are used to attach wood, metal or plastic trim to light-gauge metal or wood. The Streaker point means quick and easy penetration, while the smaller, less noticeable head provides a finished look. Grabber's No. 1 square recess is designed for secure bit engagement in trim to wood or light gauge metal applications, and the trim head screws are more evenly heat treated and tempered for consistent, reliable performance. The fine thread and extra sharp 23° Streaker point drive faster and hold better in light gauge metal and wood, and the point starts immediately and is much less likely to flop over. This version has a phosphate finish. • #7 x 2-1/4 in., #1 square drive, trim head • Fine thread with extra sharp 23° Streaker point • Phosphate finish • Attaches wood, metal or plastic trim to light-gauge metal or wood • Application: trim material attachment to light gauge steel or wood • Suggested screwgun: size #7-#8, up to 4,000 RPM • Sold as a 1 lb. box • Complies with ASTM C1513
