410/304/316 Stainless Steel pan head torx drive self drilling screw
Stainless steel 410, 304 and 316
StainGrip® 410 / 304 / 316 Stainless Steel Pan Head Torx Drive Self-Drilling Screws are high-performance structural fasteners designed for high-torque fastening, fast drilling, and reliable clamping in sheet metal, aluminum extrusion framing, electrical enclosures, HVAC components, and industrial machinery assemblies. Available across multiple stainless steel grades—including heat-treated 410 for maximum surface hardness and piercing capability, as well as SS304 and marine-grade SS316 for ultimate corrosion protection—these fasteners feature a high-profile pan head and a deep Torx (Star) drive for slip-free installation.
Key Features & Technical Benefits
Versatile Stainless Steel Options (410 / 304 / 316 Grades):
410 Stainless Steel: Heat-treated to achieve high surface hardness, enabling the screw to pierce and tap directly into structural carbon steel and metal studs without dulling or snapping the drill tip.
304 & 316 Stainless Steel: Engineered with high nickel and chromium alloys (plus molybdenum in SS316) to provide outstanding long-term resistance against rust, outdoor weathering, industrial chemicals, and marine coastal environments.
Pan Head Design (Flat Bearing Surface): Rounded top profile with a flat underside provides strong clamping force against flat metal, plastic, or composite brackets without countersinking, ensuring a clean, neat appearance.
Deep Torx Drive System (Optimal Torque & No Cam-Out): Precision star recess allows maximum engagement with the driver bit, enabling high torque transmission while eliminating driver bit cam-out, slipping, and head stripping during high-speed automated installation.
Precision Self-Drilling Tek Point: Integrated drill bit tip drills, cuts, and taps clean mating threads into metal sheets and profiles in a single operation, eliminating the need for pre-drilled pilot holes.
Full-Length Tapping Threads: Precision-formed threads extend along the length of the shank, providing deep thread engagement and high pull-out resistance under dynamic vibration.
