- Tantalum hex socket head cap screws.
- Tantalum is a material characterized by excellent chemical resistance and high specific gravity.
- With excellent corrosion resistance to strong acids such as sulfuric acid, it is also resistant to aqua regia.
- The specific gravity is approximately twice that of general steel and stainless steel.
Brackets that can be positioned the touch of a button.
While holding down the button, move the bracket to the location it should be fixed.
Release the push button to fix the bracket in place.
Pushing the button again enables the bracket to be moved to another, new desired position.
By using NBK’s Auto-Positioning Units instead of Handles, many merits can be observed:
Reducing setup time on a varied product line.
Eliminating manually operated setup errors.
Improving efficiency in difficult to reach workplaces.
Reduced wiring due to wireless communication.

- Hardening the screw surface prevents screw seizing / sticking.
- Unlike platings or coatings, there is nothing adhering to the surface, eliminating concerns about contamination due to stripping during tightening.
- Suitable for preventing seizing and sticking in environments where lubricant cannot be used.
NBK has a lot of readily available structural components.
Examples inlcude: Roller Chain Bolts, Turn Buckles, Joint Nuts and more
The main ball is surrounded by several sub balls to ensure the ball rolls smoothly.

- The friction of the nylon adhered to the thread suppresses the return rotation of the thread.
- Even if the tightening force is lost, the return rotation is suppressed, preventing the screws from falling off.
NBK’s Plungers are mechanical components for positioning and fixing workpieces.
A spring is built into the main body of the plunger so the ball or pin at the tip sinks into the body when a load is applied, and is returned to its former position by spring force when the load is removed.
- When the screw is tightened, the workpiece is strongly clamped by the head, which is decentered from the shaft center of the screw. The wedge effect creates a large clamping force with low tightening torque.
- There is a variety of outside diameters and thickness relative to normal plain washers.
- For securing seating surface on the long hole position and engagement of materials with low marginal seating surface pressure such as aluminum and resin.
- As a collar and a spacer, it can adjust the cumulative error in assembly.
- Steel and Stainless Steel a...
NBK’s Insulation type (plastic slit type) coupling series was made to assist our customers with their multitude of needs. Our standard plastic couplings however, are not limited to just the MSXP series. We also custom make plastic couplings based on customer’s needs including use in harsher environments and environments which require precision.

- Simple structure comprised of a flange and coupling bolts. Easy to mount.
- Bushings can be replaced just by removing coupling bolts. This makes maintenance and service easy.
- While it absorbs lateral, angular or axial misalignment, it also prevents noise by absorbing torsional vibration. It will not transmit thrust load either.
