ReelFast® Surface Mount Spring-Loaded Panel Fastener – Type SMTPFLSM™

SMTPFLSM-M3-1ET

ReelFast® Surface Mount Spring-Loaded Panel Fastener – Type SMTPFLSM™

New Type SMTPFLSM™ surface mount spring-loaded panel fastener provides ease of installation and high precision positioning without loose hardware. It mounts 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 aboutpotential damage to P.C. boards due to improper secondaryinstallation operations. These fasteners are provided on tape andreel compatible with existing SMT automated installation equipment.

Features and Benefits

  • All metal captive screw assemblyinstalls in one piece utilizing pick andplace method
  • Combination drive, Torx®/slot
  • Solderable finish
  • Screw length code “0” retracts flush inup position
  • Ease of installation
