For heavy-duty connections in piping systems, flanges, and industrial assemblies, double-end stud bolts are a critical component. Also known as double-ended bolts or threaded stud bolts, these fasteners provide secure clamping where nuts are used on both ends. HardHawk has over 15 years of expertise manufacturing high-performance fasteners, supplying carbon steel double-end stud bolts and stainless steel double-ended studs to customers worldwide.
What Are Double-End Stud Bolts?
A double-end stud bolt is a threaded rod with equal or unequal thread lengths on both ends, designed to be installed with nuts. This configuration is widely used in the oil & gas, chemical, power generation, and heavy machinery sectors.
Our product range includes:
- Metric double-end stud bolts M6 to M72
- Lengths from 50 mm to 3000 mm
- Multiple thread standards (UNC, UNF, BSW, DIN 976)
Whether you need ASME B16.5 stud bolts for flanges or custom threaded studs for OEM applications, HardHawk can meet your specifications.
