          LWN Self-Clinching Nuts

          Self-Locating Projection Weld Nuts – Type LWN, LWNS

          Wweld nuts (Types LWN/LWNS) provide load-bearing threads in metal sheets too thin to tap, and permit faster assembly.

           

          Brand weld nuts overcome many problems associated with other weld nuts – burn-outs, complicated electrodes and pilots, tedious time-consuming indexing and re-tapping to remove weld spatter. Their design, based on the experience of hundreds of users of weld nuts, speeds production using standard equipment, thereby reducing labor costs.

           

          Installation:
          Must always be carried out using a squeeze action-nevr a shock loadPunch a hole in the metal sheet to the size recommended in our technical data tableDe-burring of the hole is not recommended.Apply pressure to the head of the fastener sufficient to totally embed the clinching ring aroundthe entire circumference and bring body in contact with the sheet.Insert fixing screw or bolt from side opposite to the fastener body.
