2 FASTNRS FOR US WITH P BOARS an satisfy component-to-board, board-to-board, and board-to-chassis production fastening needs using less attachment hardware. BROAHING FASTNRS PM broaching fasteners can be utilized with all types of P boards, as well as with aluminum, acrylic, and polycarbonate components. They install simply, quickly, and permanently for secure and reliable attachment. Their use eliminates the need for washers, lock washers, nuts, and other excess hardware. The PM family of broaching fasteners includes broaching nuts (s KF2 and KFS2) with permanent threads for board mounting or component attachment; threaded or unthreaded standoffs (s KF and KFS) for stacking or spacing and flare mounted standoffs ( KFB3) for greater pullout performance; threaded studs ( KFH) for use as solderable connectors or as permanently mounted mechanical fasteners with external threads; all-metal standoffs ( KSSB) featuring a spring action to hold a P board securely without screws or threaded hardware; self-expanding FOILGAR fasteners ( KPS6) used in plated thru-holes in multi-layer P Boards; and one-piece board-mount screw assemblies ( PFK) with captive screws for easy mounting and removal of P boards. GROUNING STANOFFS Grounding standoffs (s SOAG and SOSG) are designed for clinching into steel or aluminum chassis. The opposite end of the standoff has gripping teeth to firmly contact mating P board.

Prepare a hole of suitable diameter so that after plating the plated hole size in board is as specified in the tabulation on page K Place fastener into the anvil hole and place the mounting hole over the shank of the fastener as shown in drawing. 3. Using a flat punch and anvil, squeeze the fastener with sufficient force so that the tips of the projecting knurl teeth are embedded and the inside shoulder of the knurl contacts the board (most of the knurl will remain visible). As the fastener seats itself in the proper position, the shank will expand outward to complete the installation. Punch and anvil surfaces must be parallel.

9 BROAHING FASTNRS For KFB3 (1) 1. Punch or drill properly sized round mounting hole in board. 2. Place fastener into the anvil hole and place the mounting hole over the shank of the fastener as shown in diagram to the left. 3. Using a punch flaring tool and a recessed anvil, apply squeezing force until the shoulder of the fastener contacts the board. As the fastener seats itself in the proper position, the punch tool will flare the extended portion of the shank outward to complete the installation. The combination of broaching and flaring provides high pushout performance. (1) Pennngineering manufactures and stocks the installation tooling for the KFB3.
