No matter how sophisticated or advanced, electronic components must be attached reliably and securely ifthey are to deliver optimum performance. We offer several fastener products for use with PC boards to satisfy component-to-board, board-to-board, and board-to-chassis attachment needs.

Threaded broaching studs for use as solderable connectors or as permanently mounted studs on PC boards.

  • 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 To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
  • 3 HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell.
  • 4 “BL” suffix will be added to part number to designate DuraBlack™ finish.
