Arrow Fastener Rivet Nut Gun Kit 8in Compact for Tight Spaces — 3 Mandrels & 75 Nuts

Arrow's 8" Rivet Nut Tool Kit is a compact manual rivet nut gun with three mandrel sizes, matching rivet nuts, drill bits, and a durable carrying case—designed to install rivet nuts in confined or hard-to-reach areas.

This RNT1 kit bundles a narrow-body 8" rivet nut gun, three commonly used mandrels (8-32, 10-24, 1/4-20), three drill bits (6mm, 7mm, 9mm), and 75 matching rivet nuts in a blow-molded carrying case. The tool's modular design and rotary knob for quick nut loading make it useful for sheet metal, automotive trim, gutters, storm doors, and other projects where space is limited. Lightweight aluminum-alloy construction with a blackened finish and a textured PVC handle give a balance of durability and comfort for extended manual use.

How does this kit help when working in tight spaces?

The gun body has a reduced width and an 8" overall length to reach narrow openings where standard rivet nut guns won't fit. Its modular, detachable nose and mandrel setup let you swap sizes without needing large clearances. The small case keeps everything organized so you can bring the right bits and fasteners to cramped job sites.

• Compact 8" gun body engineered for narrow access points
• Modular detachable nose for easy maneuvering and mandrel changes
• Rotary knob simplifies loading and releasing rivet nuts in tight spots
• Portable blow-molded case for organized transport to confined locations

What is included and which fastener sizes are supported?

The kit is a one-stop set for many common applications: you get the 8" Arrow rivet nut gun, three mandrels for 8-32, 10-24 and 1/4-20, corresponding drill bits (6mm, 7mm, 9mm), and 75 rivet nuts—25 of each size—neatly packed in a small storage box inside the case.

• Mandrels: 8-32, 10-24, 1/4-20
• Rivet nuts included: 25× 8-32, 25× 10-24, 25× 1/4-20
• Drill bits: 6mm, 7mm, 9mm for correct hole sizing
• High-quality blow-mold case and small organizer box for fasteners

How comfortable and durable is the tool for repeated use?

The gun uses a lightweight aluminum-alloy body with a blackened finish to resist wear while keeping weight down. An ergonomically curved handle with PVC non-slip grip reduces hand fatigue during multiple pulls. Note: avoid using all-steel or stainless rivet nuts sized 1/4-20 with manual operation when the manufacturer recommends against it.

• Aluminum-alloy body for strength with reduced weight
• PVC non-slip handle for comfortable repeated operations
• Blackened surface treatment for improved longevity
• Not intended for all-steel/stainless 1/4-20 rivet nuts under manual load
