Titanium Screws (Our Product - Base) | Medical devices, aerospace, electronics | Grade 2 titanium (ASTM F136) ▲ 1mm length (M1 thread) Pan head (cross recess) Plain finish | Lightweight (4.5 g/cm³) Corrosion-resistant (1000+ hours salt spray test) High strength-to-weight ratio (415 MPa tensile strength) | Higher cost vs stainless steel Requires torque control to avoid stripping |
Stainless Steel Screws (Industry Standard) | General construction, automotive | ASTM A193 Grade B8 2–5mm lengths Hex head (hex recess) Zinc-plated finish | Cost-effective Widely available Good corrosion resistance (500+ hours salt spray test) | Heavier (7.8 g/cm³) Lower strength-to-weight ratio (500 MPa) Risk of galvanic corrosion in saltwater |
Alloy Steel Screws | Heavy machinery, industrial equipment | ASTM A307 Grade A 5–10mm lengths Hex head (hex recess) Zinc-plated finish | High load-bearing capacity (600 MPa tensile strength) Durable in harsh environments | Prone to rust without coating Brittle at extreme temperatures Heavier than titanium |
Brass Screws | Marine, decorative fixtures | ASTM B26 (C26000) 3–6mm lengths Round head (slot recess) Polished finish | Aesthetic appeal Non-magnetic Resists saltwater corrosion (300+ hours salt spray test) | Low tensile strength (345 MPa) Soft material (easily deformed) Higher cost than steel |
Plastic Screws | Electronics, low-stress assemblies | Polyamide (ASTM D638) 2–4mm lengths Pan head (cross recess) Plain finish | Lightweight (1.1 g/cm³) Electrically insulating Resists chemical exposure | Low load capacity (20 MPa) Brittle at low temperatures UV degradation risk |
Titanium Screws (Our Advanced) | High-performance aerospace, medical implants | Grade 5 titanium (ASTM F1477) ▲▲ 1–6mm lengths ▲ Socket head (hex recess) Black oxide coating ▲ | Enhanced strength (896 MPa tensile strength) Expanded size range Improved tool retention | Higher cost vs Base version Specialized tooling required for installation |
