304/316 Stainless Steel Pan head Torx drive type F metal sheet screw
Stainless steel 304 and 316
StainGrip® 304 & 316 Stainless Steel Pan Head Torx Drive Type F Thread-Cutting Screws are heavy-duty, high-precision fasteners engineered for secure fastening into heavy-gauge sheet metal, structural steel, aluminum, iron castings, and rigid plastics. Manufactured from premium SS304 and marine-grade SS316 stainless steel, these thread-cutting screws feature a blunt Type F point with specialized cutting flutes that carve clean machine-screw threads into pre-drilled material, providing maximum resistance against rust, outdoor weathering, and harsh chemical environments.
Key Features & Technical Benefits
Premium SS304 & SS316 Stainless Steel (Ultimate Corrosion Resistance): High chromium and nickel alloy formulation (with added molybdenum in SS316) provides exceptional protection against rust, industrial atmosphere, chemicals, and marine corrosion.
Type F Thread-Cutting Point (Self-Tapping into Heavy Materials): Features a blunt end with multiple cutting edges and chip cavities that cut clear, precise machine threads directly into thick metals, aluminum extrusions, die castings, and dense plastics without distorting the substrate.
Rounded Pan Head Design (High Clamping Surface): The wide, domed pan head with a flat underside provides a large bearing area, distributing clamping torque evenly and securing sheet metal and component housings without causing material deformation.
Deep Torx Drive System (Cam-Out Prevention): Precision-molded star drive recess delivers optimal torque transfer, eliminating driver bit cam-out, bit slippage, and stripped screw heads during high-torque machine installations.
Vibration-Resistant Machine Thread Fit: Produces a tight, zero-clearance custom machine thread fit in the mating material, offering superior pull-out resistance and stability under dynamic vibration.
