Flange Nuts

No need for a separate washer—these nuts have a flange that distributes pressure evenly. Ideal for securing screws in oversized or irregularly shaped holes. Also known as collar nuts.

• Plain Flange— General-purpose flange nuts for a wide variety of fastening applications.
• Serrated Flange— Serrations on the flange bite into material for mild vibration resistance.
• Nylon Insert— A nylon insert grips the screw for a stronger hold than a serrated flange.
• Distorted Thread— The strongest hold of all the flange nuts we offer.
• Rotating— Won't scratch the surface of finished parts as you tighten.
• High Profile— Large gripping area keeps wrenches from slipping off as you tighten.
