Low Outgassing

These are screws made of materials and surface treatments that emit low levels of outgassing.
Due to their minimal outgassing, these screws are ideal for vacuum environments such as vacuum chambers used in semiconductor manufacturing.
There are also titanium screws with low outgassing that have undergone brightening treatment.

What are Captive Screws? Introduction of the NBK Captive Series

NBK has standardized products for fall prevention of parts in the knob, pull and e-nedzi.com (special screw) categories. Use NBK's Captive Series for food machinery, packaging machinery and chemical manufacturing equipment that require CE Marking Compliance and Contamination Control.

Vol.1　What is Seizing (Galling)?

Seized screws that won't come out are no small matter to deal with.Why does a screw "seize"? How can we prevent Galling and Seizing ?What exactly is Galling and Seizing? Nedzigon makes it all clear to you!

Vol.4　What are washers used for?

Do you know the role washers play? Preventing scratches to the seating surface?
Preventing looseness? Maybe some of you are already long-time washer users?
Today,Nedzigon will explain the role of metal washers clearly.

Vol.7　Screw Tightening Control Methods

Although fastening objects using the axial force generated from tightening is the main role of screws (bolts), in actual work, I think there are many people who control the torque by tightening with a torque wrench, because it is difficult to directly monitor the axial force, and so guarantee the axial force that way. However, there are other methods of control for tightening screws (bolts). These include those with only slightly greater axial force variation than with a torque wrench. Today, Nedzigon will tell you all about them.
