304/316 Stainless Steel Flat head Torx drive metal sheet screw
Stainless steel 304 and 316
StainGrip® 304 & 316 Stainless Steel Flat Head Torx Drive Sheet Metal Screws are high-performance self-tapping fasteners designed for flush-surface mounting in metal fabrication, machinery enclosures, plastics, and marine hardware assemblies. Manufactured from premium SS304 and marine-grade SS316 stainless steel, these sharp-pointed screws provide maximum corrosion resistance and outstanding holding power, while the flat countersunk head ensures a perfectly smooth profile without surface obstruction.
Key Features & Technical Benefits
Premium SS304 & SS316 Stainless Steel (Ultimate Corrosion Resistance): Formulated with high chromium and nickel content (plus molybdenum in SS316) to offer superior long-term resistance against rust, chemical exposure, harsh outdoor environments, and saltwater.
Countersunk Flat Head Design (Flush Finish): Sinks neatly flush into pre-countersunk holes, eliminating raised screw heads and providing a smooth, unobstructed finish across metal panels, hinges, and equipment surfaces.
Deep Torx Drive System (Cam-Out Prevention): Precision-molded star drive recess delivers superior torque transfer and tight bit engagement, completely eliminating driver bit cam-out, slippage, and stripped screw heads during assembly.
Sharp Self-Tapping Point (Self-Threading Power): Features a sharp gimlet point and precision-formed sheet metal threads that tap clean mating threads directly into pre-drilled sheet metal, thin aluminum, and rigid plastics.
High Pull-Out & Clamping Strength: Coarse, deep thread profile engages tightly along the full shank of the fastener, ensuring maximum holding power and resistance to loosening under industrial vibration.
