Install through a hole and thread on a retainer (sold separately) to keep these screws secure—no special tools are required. Use an optional spring (sold separately) to provide even compression against panels. Screws, retainers, and springs are made from chemical-resistant 18-8 stainless steel and may be mildly magnetic. Length is measured from under the head.
