Customized Stainless Steel Truss Head Black Dacromet Pan Torx Step Shoulder Screw
Product Overview
Our Customized Stainless Steel Truss Head Black Dacromet Pan Torx Step Shoulder Screw is engineered for industries requiring unparalleled durability, precision alignment, and resistance to harsh environments. Combining a truss head design for superior load distribution, a black Dacromet® coating for extreme corrosion protection, and a Torx drive for high-torque installation, this screw is ideal for aerospace, automotive, marine, and heavy machinery applications. Customizable dimensions and finishes ensure seamless integration into your critical assemblies.
Key Features
✅ Stainless Steel 316 Construction
- Corrosion Resistance: Withstands saltwater, chemicals, and extreme temperatures (-50°C to 300°C / -58°F to 572°F).
- High Tensile Strength: 620 MPa ultimate tensile strength for heavy-load applications.
✅ Black Dacromet® Coating
- Advanced Protection: Zinc-aluminum flake coating provides 1,000+ hours of salt spray resistance (ASTM B117).
- Low Friction: Dry-film lubricity reduces galling during installation.
✅ Truss Head Pan Torx Drive
- Wide Bearing Surface: Distributes load evenly, preventing material deformation in soft substrates.
- Torx (Star) Drive: Tamper-resistant, high-torque transfer with reduced cam-out risk (ISO 10664 compliant).
✅ Precision Step Shoulder
- Unthreaded Shoulder: Ensures exact alignment of bearings, bushings, or rotating components.
- Smooth Surface Finish: Minimizes wear on mating parts in dynamic assemblies.
✅ Customizable Dimensions
- Thread Sizes: M4–M20 (metric) or #8–¾" (imperial).
