Tantalum Fasteners
Tantalum fasteners including screw, bolt, stud, threaded rod, nut, washer.
During production of tantalum fasteners, comprehensive manufacturing methods are applied in order to guarantee the precision that our customers expect.
鈼?Lathing and CNC lathing - for surface and threads
鈼?Milling and CNC milling - for screw's head
鈼?Drilling and punching - for washers
鈼?Threads rolling - for threads
Finished tantalum fasteners will be appropriately annealed to relief residual stress.
