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 a precision recess 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. Sharp threads drive faster and hold better in light gauge metal and wood, and the extra sharp 23° Streaker point starts immediately and is much less likely to flop over. Grabber recommends them for trim material attachment to light gauge steel or wood, and the screws comply with ASTM C1513 requirements. The finish is phosphate. • #7 gauge x 2-1/4 in. length, #1 square drive, trim head • Fine thread with extra sharp 23° Streaker point • Phosphate finish • Application: trim to metal or wood • Recommended application: trim material attachment to light gauge steel or wood • Suggested screwgun: size #7-#8, up to 4,000 RPM • Sold as a 5 lb. box • Complies with ASTM C1513
