Spiralock® Self-Clinching Nuts (Fractional Sizes)
Our Self-Clinching Nuts in fractional sizes are load-bearing threaded fasteners for thin sheets. They work best when used with aluminum, steel, and other ductile materials.
These load-bearing threaded fasteners feature a clinching ring that locks the displaced metal behind the tapered shank ensuring high pushout resistance. High torque-out resistance is ensured when the knurled platform is embedded in the sheet metal.
Our Self-Clinching Nuts are made to order and come in a wide range of fractional sizes.
