Simpson Strong-Tie's Large Hex-Washer-Head Fine-Thread Self-Drill Galvanized Shoulder Screws delivers jobsite efficiency with its self-drilling capability and controlled installation depth. The oversized hex-washer head is designed to resist pull-through while increasing clamping area, which helps secure sheet metal, brackets, and other steel components with confidence. Its threading promotes secure engagement in steel substrates, and the compact 3/4 in. length is ideal where minimal penetration is required. Each 83-pack provides ample coverage for mid-sized assemblies, offering professional-grade quality in a manageable quantity. From fabrication shops to field installations, this screw supports consistent, high-performance fastening across a wide range of industrial applications.
