Might Wrong Complaining ...

You thought that is a product issue but at the end you just release that is a wrong driver bits used...

Normally, you cannot/ not easy to recognize it either is Torx (T) or Torx Plus (IP) recess by bear eyes when you receive piece of screws. There is not easy to recognize the pattern if you has no knowledge of fastener. But, there is a different between Torx and Torx Plus driver bits. Some of people will say why do they create/ invent with different type of driver bits or recesses? There is all about product enhancement which Torx Plus (IP)recess/ driver bit is better of grip functional if compare with Torx (T)recess/ driver bit. 



Differentiation between two types of drive bits/ recesses

Why I say “I thought I am right” or “wrong complaining”? If there is involving product change or new item buying without inform/ massage pass it to production operator, for example screws with recess Torx changed to screws with recess Torx Plus. Majority operators will use Torx drive bit to fix to screws with Torx Plus recess. And the problem is Torx drive bit is still able to fix it for tightening. However, there is a high risk to face a stripping issue if using wrong type of drive bit for tightening. This is common problem highlighted from production operator.  


Circumstances here;
  1.        Torx drive bit can be fixing to Torx Plus recess
  2.        Torx Plus drive bit cannot be fixing to Torx recess

Similar design between Pozi VS Philips
  1.        Pozi drive bit cannot be fixing to Philips recess
  2.        Philips drive bit can be fixing to Pozi recess


Let see above the picture why can be caused a stripping if we using wrong type of drive bits. The angle of design is different to cause it not fully engagement between driver bit and recess.

Be careful when you face stripping issue on top of recess. You might study on recess and driver bit as matching first before highlight to other party.

Innovation test methods

Hydrogen Embitterment (HE) test:-

Just twist a bit your mind, you can improve a productivity for speeding up the time period for Hydrogen Embitterment (HE) test. Below pictures shown as innovation test and conventional test method which used metal plate for testing.

 Innovation test method
Conventional test method

 It could taken long period for assembly piece of screws onto plate if using conventional method. However, just take one shot of assembly (innovation applied) to many of pieces of screw with using bolts, flat washer and nut. The objective and result is similar and nothing affected for both of elements. 

Innovation can be made you feel fun, minimize of sources needed (plate, tools and so on) and productivity.
