Arrow Fastener 8" Rivet Nut Tool Kit — Compact Rivet-Nut Gun for Tight Spaces with 3 Mandrels & 75 Nuts

The Arrow RNT1 8" Rivet Nut Tool Kit is a compact, manual rivet nut gun and complete accessory set built to install blind rivet nuts in tight or hard-to-reach locations.

Whether you’re retrofitting sheet metal, repairing automotive pieces, or fastening storm doors and gutters, this kit combines a shortened gun body with three mandrel sizes, drill bits, and 75 matching rivet nuts stored in a blow-mold case so you have everything on hand. The tool’s smaller profile and modular design make it easier to work where standard nut guns won’t fit, while the included bits and fasteners eliminate the need to source extras.

How does the smaller gun body help in cramped spaces?

The RNT1’s reduced-width gun body is engineered to fit into narrow cavities and between close-clearance panels where full-size tools can’t access. Its detachable modular construction lets you change mandrels quickly and orient the tool more effectively in tight spots.

• 8" overall length with narrow body for confined access
• Modular, detachable mandrel system for faster swaps
• Rotary knob for straightforward nut loading and release

What comes in the kit and why is it useful?

This one-stop kit includes the 8" rivet nut gun, three mandrel sizes (8-32, 10-24, 1/4-20), three drill bits (6mm, 7mm, 9mm), and 75 pre-matched rivet nuts (25 of each size) packed in a small storage box. Everything fits into a durable blow-mold case so you can keep components organized and transport them to job sites easily.

• Three mandrels match the most common nut sizes for fast setup
• Drill bits allow pre-drilling to correct hole sizes without searching for extras
• 75 rivet nuts provide immediate parts for multiple repairs or installs

Is the tool comfortable for extended use and durable?

The lightweight steel body with an aluminum alloy construction and blackened finish balances strength with reduced fatigue. The molded PVC non-slip handle conforms to your hand for easier squeezing, while the lighter gun weight helps reduce wrist strain during repetitive operations.

• Ergonomic PVC handle for improved grip and comfort
• Aluminum alloy body and blackened surface for corrosion resistance
• Not recommended for all-steel or stainless 1/4-20 rivnuts with manual operation

How do I know this kit fits my projects?

The RNT1 is aimed at general fabrication and repair tasks: sheet metal work, automotive repairs, gutter and door fastenings, and other DIY or professional jobs that need strong threaded anchors in thin materials. It supports the most common imperial rivet nut sizes and includes the drill bits and fasteners to get started immediately.

• Supplied rivet nut sizes: 8-32, 10-24, 1/4-20
• Ideal for thinner substrates where a threaded insert is required
• Hand-operated design suited for spot repairs and on-site use

Who this is for: The Arrow RNT1 Rivet Nut Tool Kit is built for professional technicians, body shops, maintenance crews, and serious DIYers who need a compact, portable rivet nut solution. If you frequently work in confined spaces or want a complete starter set of mandrels, bits, and rivet nuts in a rugged case, this kit provides a practical, ready-to-use option without relying on pneumatic or power-operated systems.
