Product Details
The Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screw in 316 Grade Stainless Steel is a high-strength structural wood screw with a 0.250" shank ideal for various metal connector installations. Due in part to its knurled shank and Type-17 point, it installs with no predrilling and has been extensively tested in various applications.
The SDS Strong-Drive 1/4" wood screw is available in 1 1/2" to 3 1/2" lengths, suitable for fastening Simpson Strong-Tie stainless-steel connectors. Offering the same easy-driving, split-reducing installation of the standard SDS screw, these screws are appropriate for high-exposure environments where maximum corrosion-resistance is required.

Grades of Stainless Steel
304/305 Grades
Thesw two grades share 98% of the elements making up their alloy composition, with 305 having slightly more carbon. A very popular choice with excellent corrosion resistance and good qualities of strength. Slightly cheaper than 316 Grade, it is a durable and aesthetically pleasing choice for all construction applications.
316 Grade
The addition of molybdenum to the mix is what sets this Marine Grade Stainless Steel apart. Used in highly corrosive environments, this grade is the ultimate choice for structures built close to or even within the ocean or bodies of water. There is no better material for fasteners designed for coastal applications, including docks, jetties, decks, fences and roofs.
