Name: Steel Flanged Hex Head Screws for Wood&Stainless Steel Flanged Piercing Screws for Sheet Metal
Material: Carbon steel, Alloy Steel, stainless steel SUS304, SUS316
1. Steel Flanged Hex Head Screws for Wood. These steel screws are hot-dipped galvanized to resist corrosion in wet environments and are a good choice for ACQ-treated (arsenic-free) lumber. The flange reduces the risk of crushing material and the hex head provides a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Head height includes the flange. Length is measured from under the head.

2. Stainless Steel Flanged Piercing Screws for Sheet Meta. Made from 410 stainless steel, these screws are strong, wear-resistant, mildly chemical-resistant, and magnetic. They're not for use with aluminum sheet metal. Also known as needlepoint screws, they're designed with a pointed tip to pierce a starter hole in sheets up to 0.050"" thick. All have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal. Length is measured from under the flange. Head height includes the flange.
