Product Overview
Double End Studs DIN939 are threaded rods with thread on both ends and an unthreaded shank in the center. These studs are mainly used in situations where high clamping force and torque transfer are required, particularly when one end is to be permanently mounted while the other side can be disassembled and reused multiple times.
Key Features:
- Manufactured according to DIN939 standard
- Constructed from robust stainless steel
- Offers strong resistance to rust and corrosion
- Ideal for static and dynamic loads
- Available in a variety of thread sizes and lengths
