          LWN Self-Clinching Nuts

          Self-Locating Projection Weld Nuts – Type LWN, LWNS

          Weld 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.

          Self-Locating Projection Weld Nuts – data
            Q1: What are Self-Locating Projection Weld Nuts (Type LWN/LWNS) used for?
            A: These weld nuts provide strong, load-bearing threads in metal sheets that are too thin to be tapped directly. They significantly accelerate assembly processes while maintaining high reliability.

            Q2: What advantages do Brand weld nuts offer over conventional designs?
            A: Our weld nuts effectively address common industry challenges:
            - Eliminate burn-outs during welding
            - Work with simple, standard electrodes (no complex pilots required)
            - Self-locating design avoids tedious indexing
            - No need for post-weld re-tapping due to weld spatter
            - Enable faster production using standard equipment
            - Reduce overall labor costs

            Q3: What is the proper installation procedure?
            A: Correct installation requires these critical steps:
            1. Tool Action: Always use a controlled squeeze action - never apply shock loads
            2. Hole Preparation: Punch a hole to the exact size specified in our technical data table
            3. Surface Condition: Do not de-burr the hole after punching
            4. Clinching Process: Apply sufficient pressure to fully embed the clinching ring around its entire circumference until the nut body contacts the sheet
            5. Fastener Installation: Insert screws or bolts from the side opposite the fastener body
