Collated Cap Fasteners

Cap Fasteners

  • Cap fasteners are a recommended best practice installation by housewrap and roofing underlayment manufacturers such as DuPont Tyvek.
  • Caps help to seal out moisture that can penetrate sidewall and roofing fabrics.
  • Caps provide better holding power than a nail or staple alone, which means fewer fasteners are needed to complete the job.
