- 2H Heavy Hex Nuts – Carbon Steel (ASTM A194 2H)
- Flange Face Bolts – Carbon Steel or Alloy Steel with PTFE/Zinc Coating
- High-Pressure Hex Bolts – Quenched and Tempered Alloy Steel
- Threaded Rods – 304/316 Stainless Steel
- Sealing Washers – Stainless Steel + Rubber or PTFE Sealing Layer
Solar and Wind Industry Solutions
Fasteners used in renewable energy must offer excellent resistance to UV exposure, moisture, and corrosion, often in outdoor or coastal environments. Materials like stainless steel or surface-treated carbon steel ensure structural durability and long service life for installations such as solar racking and wind turbines.
- Bolts – 304/316 Stainless Steel
- T-slot Bolts – Hot-Dip Galvanized Carbon Steel or A2 Stainless Steel
- Lock Nuts – Nylon Insert Carbon Steel or Stainless Steel
- Flat Washers – A2/A4 Stainless Steel
- U-Bolts – HDG Carbon Steel or 316 Stainless Steel
- Self-Tapping Screws – 410 Stainless Steel or Zinc-Plated Carbon Steel
Pipeline Valve Industry Solutions
Precision and sealing performance are critical for fasteners used in pump and valve applications. These components are exposed to pressure, vibration, and sometimes corrosive fluids, requiring durable, leak-proof fastening solutions.
- Flange Bolts – Carbon Steel or 304/316 Stainless Steel
- Hex Head Bolts – Alloy Steel or A2/A4 Stainless Steel
- Sealing Washers – Metal + Rubber (EPDM/NBR) Composite
- Stud Bolts – B7 Alloy Steel or 316L Stainless Steel
- Socket Head Cap Screws – Alloy Steel (Grade 12.9) or Stainless Steel
- Castle Nuts – Carbon Steel or 304 Stainless Steel
Automotive Industry Solutions
Automotive fasteners are designed for mass production and high-performance requirements. They must be lightweight yet strong, capable of withstanding vibration, high temperatures, and fatigue over long periods. Precision and consistency are essential.
- Flange Bolts – Carbon Steel with Zinc or Phosphate Coating
- Machine Screws – Low Carbon Steel or Stainless Steel
- Weld Nuts – Low Carbon Steel (Weldable Grade)
- Cage Nuts – Spring Steel or Stainless Steel
- Self-Tapping Screws – Hardened Steel with Zinc Coating
- SEMS Screws – Carbon Steel with Pre-Assembled Washer, Zinc Plated
Rail Transit Industry Solutions
The rail transit industry requires high-strength fasteners that can endure dynamic loads, vibration, and harsh outdoor environments. Fasteners must meet safety-critical standards and offer long-term fatigue resistance for infrastructure such as tracks, train cars, and signaling systems.
- Rail Clip Bolts – High Tensile Carbon Steel, HDG or Black Oxide Finish
- High-Strength Hex Bolts – Grade 10.9/12.9 Alloy Steel
- Spring Washers – Carbon Steel or 65Mn Spring Steel
- Torque Shear Bolts – Structural Steel with Corrosion-Resistant Coating
- Square Head Bolts – Carbon Steel, Hot-Dip Galvanized
- Vibration-Resistant Nuts – Alloy Steel with Nylon or All-Metal Locking
Marine Engineering Industry Solutions
Marine and offshore applications demand fasteners that perform in saltwater, humidity, and high-wind conditions. These environments require corrosion-resistant materials like 316 stainless steel, duplex stainless, or titanium, ensuring structural integrity over extended use.
- 316 Stainless Steel Bolts – Marine-Grade Stainless Steel (A4-70/A4-80)
- Duplex Stainless Steel Nuts – UNS S31803/S32750 Duplex Stainless
- Anti-Loosening Screws – 316 Stainless Steel with All-Metal Locking
