 W and d1 are the control values for thread inserts (Free Running ) before they have been installed.

 The length can only be measured for installed thread inserts.

         image

d          =  Nominal thread diameter

P          =  Thread pitch

d1        = Outside diameter of thread insert prior to installation

W         = Number of threads prior to installation

DHC     = Outside diameter of the parent thread

D1HC   = Crest diameter

B          = Suitable twist drill diameter. Please note:

               D1HC is critical for selecting the correct twist drill diameter

t1         = Minimum depth of tapped hole

t2         = The nominal length of the thread insert corresponds to the minimum length of the full parent thread for blind

               holes or the minimum plate thickness for a through hole

t3         = Maximum screw-in depth when the tang is not removed

t5         = Distance of the thread insert from the joint face = 0.25 to 0.5 P, if t2 corresponds to the above mentioned 

                minimum value

 

Material :

● Stainless steel grade 304 (AS7245) austenitic corrosion resistant steel. 

   For normal applications up to 425°C .

● Stainless steel grade 316 (AISI 316) austenitic corrosion resistant steel. 

   For Marine applications up to 425°C .


Coating & Finishing :

 ● Silver Plating

    Primarily used to reduce the effects of screw thread seizure in high temperature applications.

● Coloured Dye

    Red, blue and green colour dyes are available for fast and secure visual inspection and identification. These organic                      resin based dyes do not affect the installation or function of the inserts and normally do not need to be removed.
