Material |
- Carbon Steel (Grade 2, 5, or 8, with Zinc Plating) - Stainless Steel (304/316, A2-70) - Silicon Bronze (For Marine/Outdoor Use) - Hot-Dip Galvanized (Heavy-Duty Corrosion Resistance) |
Finish |
- Clear Zinc (RoHS Compliant, Salt Spray: 200+ Hours) - Yellow Zinc (Enhanced Corrosion Resistance, 500+ Hours) - Black Oxide (Aesthetic + Moderate Corrosion Protection) - Phosphate Coating (For Improved Paint Adhesion) |
Design Features |
- Hex Head: Allows quick installation with hex key/wrench, provides high torque transfer. - Self-Tapping Threads: Sharp, deep threads reduce splitting; optional thread types: - Type 17 (Aggressive Cutting for Hardwoods) - Type 10 (Standard for Softwoods) - Counterbore Shank: Reduces risk of splitting in dense woods. - Bugle Tip: Ensures flush seating, ideal for drywall/wood paneling. - Lobular Threads: Increase pull-out resistance by 30% compared to standard threads. |
