CRL 5/16-18 A-T Series Threaded Insert Fasteners

• Blind installation (installs from one side) for light to medium duty fastening
• Installs load threads in virtually any material: aluminum, magnesium, steel, cast iron, plastics, fiberglass, or hardboard
• One insert fits any material thickness above 0.030" (0.76 mm), reducing inventory
• Vibration-proof; ideal for threaded, load-bearing connections
• Use to install Z-clamps to posts or for other sheet-metal and panel assemblies

CRL Riv-Nuts Steel Insert Fasteners (SKU: ATS2518) are blind rivet nut-style steel insert fasteners designed for light- to medium-duty applications. They install from one side—making them perfect for blind or hard-to-reach joints—and work in thinner materials more easily than weld nuts, pierce nuts, clinch nuts, thread-tapping, or thread-forming screws. These non-grip-sensitive steel riv-nuts eliminate multiple grip ranges: one part number per thread size fits any grip over 0.030" (0.76 mm).

The distinguishing axial knurl beneath the flange bites into the parent material during sleeve expansion, delivering superior torque resistance and wear-resistant threads. Use these steel riv-nut inserts to speed production, simplify inventory, and improve joint reliability. They suit high-speed automated lines and low-volume manual installations alike.

Features:
• Wear-resistant threads thanks to the mechanical expansion installation method.
• Easy to learn installation—no special skills required.
• High-speed production capable—up to 500 pieces per hour.
• Self-tightening behavior with repeated use.
• Fits standard drilled or punched holes; no deburring required.
• Installable at any assembly stage with portable tools; can be installed after painting or plating.
• Metric and alternate materials (aluminum, brass, stainless steel) available by special order.

Product Warning:

For guidance on matching insert size to parent metal thickness, consult CRL technical resources or contact Customer Service before ordering.
