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.
