Trivd Frol 16" Rivet Nut Tool Kit — 15 Mandrels & 281 Rivnuts, 16-inch Long-Leverage Hand Gun

Trivd Frol 16" Rivet Nut Tool Kit is a heavy-duty hand rivet nut gun with 15 interchangeable mandrels and 281 rivet nuts for reliable blind nut installation in metal, plastic and composite panels.

This comprehensive kit supplies a long-leverage 16-inch rivet nut gun, a broad range of mandrel sizes (metric and SAE), 281 assorted rivnuts, and a rugged blow-molded storage case — everything needed to add threaded inserts where access is limited. The tool’s heat-treated carbon steel construction and black-phosphate finish resist wear and corrosion while a TPR shock-proof grip and longer handle reduce effort for repeated jobs. Whether you’re retrofitting automotive panels, building furniture, or doing general sheet-metal work, the kit is built to give consistent, clean blind-threaded connections.

How does the longer 16" handle help when setting rivet nuts?

The extended handle increases mechanical leverage so you exert less force for the same clamping action, minimizing hand fatigue on multiple fastenings. It’s useful for thicker or tougher materials where a short-handle tool would struggle.

• 16-inch arm provides greater leverage and smoother compression
• U cross-section arm resists bending under heavy loads
• TPR shock-proof grip improves comfort and control

Which mandrel and rivnut sizes are included, and can I change them easily?

The kit contains 15 interchangeable mandrels covering both metric and SAE sizes and 281 rivnuts across common diameters. Mandrels can be swapped by hand without extra tools, and the gun ships with the 1/4-20 mandrel already installed for immediate use.

• Metric mandrels: M3, M4, M5, M6, M8, M10, M12
• SAE mandrels: 6-32, 8-32, 10-32, 10-24, 1/4-20, 5/16-18, 3/8-16, 1/2-13
• Tool-free mandrel changes speed up size swaps and maintenance

What materials and applications is this rivet nut tool suitable for?

Made from heat-treated carbon steel with a corrosion-resistant black-phosphate finish, the rivet nut gun is designed for demanding workshop and field use. It performs well on thin-gauge steel, aluminum, plastic, and composite panels where blind-side access is not possible.

• Automotive body panels, repair and retrofit work
• Sheet metal fabrication, HVAC brackets, and metal cabinets
• Plastic housings, furniture assembly, and light structural joins

How durable and low-maintenance is the kit for frequent use?

The tool’s hardened components and sturdy construction reduce deformation and wear over time, while the black-phosphate coating helps resist rust. Routine cleaning and occasional lubrication keep the mechanism smooth; mandrels are user-replaceable for easy service.

• Heat-treated carbon steel body for strength and longevity
• Black-phosphate finish resists corrosion in workshop environments
• Replaceable mandrels and accessible parts simplify repairs

Who is this for: Tradespeople, automotive hobbyists, metal fabricators and DIYers who need a reliable, portable solution for installing blind threaded inserts will benefit most from the Trivd Frol 16" Rivet Nut Tool Kit. It’s geared toward users who want a broad size range, durable construction, and a compact, organized kit to handle repairs, installations, and small-production fastening tasks without investing in power-hydraulic equipment.
