Part # SMTSO-080-4ET, ReelFast® microPEM® Surface Mount Nuts / Standoffs

Surface mount ReelFast® microPEM® (Type SMTSO™) fasteners for compact electronic assemblies attach to P.C. Boards for nut/standoff applications. These fasteners mount on P.C. Boards in the same manner and at the same time as other surface mount components prior to the automated refl ow solder process. The fasteners simply become another board component.

Features and Benefits

Hex shaped barrel provides larger solder area.
Provided on tape and reel.
Reduces board handling.
Smallest thread size: M1 / #0
