Engineered to seal critical fluid pathways under extreme pressure Our Hex Socket Oil Pipe Plug Screws combine ISO-compliant machining with advanced sealing geometry to prevent leaks in hydraulic, lubrication, and compressed air systems. Featuring a recessed hex drive and precision threads, they withstand 10,000+ PSI while resisting vibration-induced loosening.
Where geometric efficiency meets automotive durability Our hexagonal car parts leverage the mechanical advantages of six-sided designs for maximum torque transfer, vibration resistance, and space optimization. CNC-machined to tolerances ≤0.02mm, these components deliver OEM-grade performance in critical systems from EV batteries to suspension assemblies.
Engineered for rapid assembly where tools are impractical Our 304 Stainless Steel Wing Nuts combine marine-grade corrosion resistance with ergonomic hand-tightening capability. Featuring precision-cast wings and ISO-compliant threading, they deliver secure fastening in marine, chemical processing, and outdoor installations where conventional tools can't be used.
Where protection meets aesthetics Engineered for critical environments, our 304 Stainless Steel Cap Nuts combine superior corrosion resistance with a precision-polished dome that conceals threads while providing a finished appearance. Ideal for marine hardware, food processing equipment, and architectural installations where both durability and visual appeal are essential.
