The misalignment between a ball stud and clip can occur in two different directions, X-X and Y-Y, and each allowable tolerance must be evaluated differently.

Figure 1 Materials can be added to screw threads to prevent loosening due to vibration. Referred to as “non-metallic vibration resistant elements”, they are more commonly known as “patches” and usually made of nylon, Figure 1. The locking elements produce...

PENCOM’s PF screws have a unique thread forming design conceived expressly for thermoplastic materials. The distinctive thread profile allows reduced boss wall thickness, maintains clamp load and resists loosening during vibration, reduces drive torque while increasing stripping torque, and reduces...

PENCOM’s PLAST48-2 screws incorporate a 48° flank twin lead thread with a trilobular body. The sharp coarsely-spaced threads provide a deep engagement in the plastic to reduce stress during thread forming; while the steep thread helix angle results in reduced...

Introduction Self-clinching fasteners are pressed into holes in ductile metal sheets to create a permanent union with the host material and replace one or more pieces of traditional loose hardware or extruded/tapped holes in panels and brackets, Figure 1. A...

Drill hole in P.C. board.Insert standoff in anvil and align sheet hole with shank of fastener as shown, Figure 1.Squeeze the standoff and sheet between parallel punch and anvil surfaces. Use only enough pressure to seat the standoff shoulder flush...
