Type SMTSO - ReelFast® surface mount nuts and standoffs are available threaded and unthreaded.

ReelFast® surface mount fasteners mount on PC boards in the same manner and at the same time as other surface mount components prior to the automated reflow solder process. The fasteners simply become another board component. This alleviates concerns about potential damage to PC boards due to improper secondary installation operations. The fasteners are provided on tape and reel compatible withmore

  • 1 The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L”
  • 2 HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell.
  • 3 “BL” suffix will be added to part number to designate DuraBlack™ finish.
