HARDELL 14" Rivet Nut Tool Kit — 14-inch Rivnut Tool with Quick-Change Head, 7 Mandrels & 100 Rivet Nuts

HARDELL's 14-inch rivet nut tool kit is a heavy-duty hand tool set that installs threaded rivet nuts quickly and cleanly, and includes seven mandrels plus 100 rivet nuts in a compact carrying case.

This kit combines a long-leverage 14" rivnut tool with a quick-change head, seven common metric and inch mandrels, and a supply of 100 rivet nuts — all packed in a molded case for storage and transport. It’s built from heat-treated high-carbon steel with a U-shaped rivet arm and ergonomic handles designed to resist bending and reduce hand fatigue. The tool works on sheet metal, plastics, and other thin substrates where a permanent, load-bearing threaded insert is required.

How does the quick-change head make my job faster?

The quick-change head lets you swap mandrels and heads without extra tools, cutting downtime when switching rivet sizes. This is useful on mixed projects or assembly lines where you frequently change fastener types.

• Tool-free mandrel swaps for rapid size changes
• Seven mandrels cover common M6–M10 and inch sizes
• Reduces handling time between inserts

Which rivet nut sizes are included and what materials does it handle?

The kit includes seven mandrels covering M6, M8, M10, 10-24, 1/4-20, 5/16-18 and 3/8-16, plus a selection of 100 rivet nuts suited for those threads. It’s engineered for metal panels, plastic parts and thin-wall tubing used in automotive, bicycle accessories, HVAC, and general fabrication.

• Mandrels: M6, M8, M10, 10-24, 1/4-20, 5/16-18, 3/8-16
• Works on steel, aluminum, and many plastics
• Ideal for retrofits, repairs, and production use

Is the tool durable and how does its design reduce effort?

HARDELL constructed the tool from heat-treated high-carbon steel with a reinforced U-shaped arm to resist distortion under load. An extended steel lever combined with a TPR-sleeved ergonomic handle increases mechanical advantage, so you use less force to set rivet nuts reliably.

• Heat-treated high-carbon steel resists corrosion and bending
• Lengthened arm and 35CrMo screw material for extra leverage
• Comfort TPR handle reduces hand fatigue on repetitive tasks

What comes in the case and how portable is the kit?

The molded carrying case stores the 14" tool, the quick-change head, seven mandrels, and 100 rivet nuts in organized compartments for safe transport and easy inventory. The compact footprint makes it convenient for jobsite work, service vans, or shop benches.

• Molded carrying case with specific slots for each component
• 100 rivet nuts included to start multiple jobs immediately
• Compact for van, toolbox, or shelf storage

Who is this for: The HARDELL 14" rivet nut tool kit is aimed at professional mechanics, fabricators, installers, and DIYers who need a durable, versatile solution for adding load-bearing threaded inserts to thin materials. If you install accessories on vehicles, assemble metal frames, or perform maintenance that requires reliable threaded attachment points, this kit provides the mandrels, hardware, and leverage to get the job done faster and with long-lasting results.
