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.

Hex shaped barrel provides larger solder area.
Provided on tape and reel.
Reduces board handling.
Smallest thread size: M1 / #0-80.
Minimum sheet thickness 0.5 mm / .020".
RoHS compliant.

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 Packaged on 13" recyclable reels. Tape width is 16 mm. Supplied with polyimide patch for vacuum pick up. Reels conform to EIA-481. ³ “BL” suffix will be added to part number to designate DuraBlack™ finish.
