410/304/316 Stainless Steel #10*1 hex head self drilling screw
Stainless steel 410, 304 and 316
StainGrip® 410 / 304 / 316 Stainless Steel #10 x 1" Hex Washer Head Self-Drilling Screws are heavy-duty, high-performance structural fasteners designed for rapid piercing, superior clamping, and maximum shear holding power in metal-to-metal framing, sheet metal, steel joists, HVAC equipment, and industrial cladding. Manufactured across multiple stainless steel grades—including heat-treated 410 for maximum piercing hardness, as well as SS304 and marine-grade SS316 for ultimate corrosion protection—these fasteners feature an integrated hex washer head that evenly distributes high clamping loads without requiring separate flat washers.
Key Features & Technical Benefits
Versatile Material Selection (410 / 304 / 316 Stainless Steel):
410 Stainless Steel: Heat-treated for extreme surface hardness, allowing the screw to drill and tap directly into structural carbon steel framing without snapping or dulling the drill tip.
304 & 316 Stainless Steel: Delivers outstanding long-term resistance against rust, weathering, industrial chemicals, and marine saltwater environments.
Hex Washer Head with Integrated Flange: Features an external hex drive combined with a broad, flat bearing flange that distributes clamping pressure across a large surface area, preventing material crushing, panel deformation, and pull-through failures.
Precision Self-Drilling Tek Point: Integrated drill bit tip drills, cuts, and taps clean mating threads into steel and aluminum in one fluid operation, completely eliminating the need for pre-drilled pilot holes.
High-Torque Drive Engagement: The external hex drive allows complete 6-point wrench or nut setter engagement, maximizing torque transmission and eliminating driver bit cam-out, slippage, and head stripping during high-speed installation.
Full-Length Deep Threads: Precision-formed tapping threads provide deep engagement along the full length of the shank, delivering high pull-out resistance and long-term joint integrity under dynamic vibration.
