Semi-Tubular Rivet Hand Setting Tool

This 2 3/4-inch hand-setting tool is designed for roll-crimping semi-tubular rivets used in U.S. helmet liners across all eras. Made from high-quality steel, it delivers reliable, repeatable results once you get the technique down, making it an essential part of any helmet restoration setup.

Please note: Because these tools are manufactured from carbon steel and stored in our Wisconsin workshop, they may exhibit minor cosmetic surface oxidation or light rust spotting. This is a normal characteristic of unfinished steel tools and does not affect function, performance, or service life, and any discoloration can be easily removed with light oil or fine steel wool if desired.

Features

• Compact & precise – 2 3/4 inches for excellent control

• Purpose-built for restorers – Works with semi-tubular rivets in all U.S. helmet liners

• Durable steel construction – Built for long-term use

• Consistent results – Produces a clean, tight roll-crimp when used correctly

• Made for workshop use – Designed as a working tool, not a display piece

⚠️ Important Note on Technique

This tool absolutely works, but it takes practice to master.

We used a tool just like this exclusively for two years and, at our peak, could fully rivet a liner in about 90 seconds. With repetition, you’ll get tight, professional results every time.

To use it effectively:

• You must work on a hard, non-flexing surface.
  Any bounce or flex — even slight — will prevent the rivet from setting cleanly.

• Expect a bit of trial and error at first.

• If you’re new to setting rivets, consider picking up extra rivets to practice before working on your liner.

Once you get the feel for it, this tool becomes indispensable.

❌ Will Not Work With Paratrooper Snaps

This tool cannot be used to set the paratrooper DOT snaps we sell.

Using it on parachutist snaps will crush and destroy the small copper ring inside the socket (the female portion of the snap). These snaps require a dedicated DOT snap setter, not a tubular rivet tool.
