Fastening Solutions UK have expanded their range of stock sizes of their popular FSUK HISH range of threaded brass Inserts by introducing a range of non preferred lengths in M4 – shorter than the standard stock range. The headed brass insert which can be installed into most Thermoplastics by either direct heat or Ultrasonics, are now available from stock in the following sizes:

M4-4.8 and M4-5.8

We can also offer other sizes which can be made to order and called off as required.
