Product Description: N/A Category: Tags: ,

Features

  • Provide load-bearing threads in thin sheets.
  • Available in a broad selection of inch and metric thread sizes.
  • Self-clinching design provides quick and permanent installation in a variety of aluminum and cold-rolled steel sheet thicknesses.
  • Choice of RoHS-compliant materials and finishes.

Sheet metal displaced by the knurled band during installation flows into the undercut creating a mechanical lock with the sheet metal providing high push-out and torque-out resistance.

  2. Custom materials and finishes available by request.

Installation

  1. Prepare correct sized mounting hole in sheet away from bends or other highly cold-worked areas. Do not deburr hole edges.
  2. Insert nut into anvil recess or over anvil pin, depending on anvil type required. Place sheet hole over the nut shank as shown with hole punch side of sheet against the nut.
  3. Squeeze the sheet and nut between parallel anvil and punch surfaces. Use only enough pressure to seat the nut shoulder flush with the sheet. Anvils and punches may be ordered using the part numbers shown in the tables below; or made from hardened tool steel.
  4. In the application install screw from the shank side of the fastener so that the head side of the nut is drawn toward the sheet.
