ReelFast® Surface Mount Captive Panel Screws
NEW

t New Type SMTPFLSM™ surface mount spring-loaded captive panel screws provide ease
of installation and high precision positioning without loose hardware. They mount on P.C.
boards in the same manner and at the same time as other surface mount components prior
to the automated reflow solder process. This alleviates concerns
about potential damage to P.C. boards due to improper secondary
installation operations. These fasteners are provided on tape
and reel compatible with existing SMT automated
installation equipment.
