Marson HP-2 Hand Riveter 39000 — Professional blind riveter, 3/32–3/16 in capacity, square-shoulder fulcrum

The Marson Sherman 39000 HP-2 is a professional hand riveter built with a square-shoulder fulcrum pin and heavy-duty components for consistent, long-lasting blind riveting of steel, aluminum, and stainless fasteners.

This compact yet robust hand rivet tool is designed for tradespeople, fabricators, and serious DIYers who need a reliable tool for structural and light-industrial riveting. It accepts aluminum and steel rivets from 3/32" to 3/16" and stainless rivets up to 5/32", pairing a high-strength aluminum alloy body with a drop-forged carbon steel upper handle and cushioned grips for comfortable, controlled use.

What materials and rivet sizes can the HP-2 handle?

The HP-2 supports a range of common blind rivets for metal and mixed-material assemblies. It is suitable for aluminum and steel rivets from 3/32" to 3/16", and stainless rivets up to 5/32". This covers many panel, bracket, and trim applications.

• Aluminum and steel rivets: 3/32" (2.4 mm) to 3/16" (4.8 mm)
• Stainless steel rivets: up to 5/32" (4.0 mm)
• Ideal for metal-to-metal, metal-to-composite, and light structural joints

How does the square-shoulder fulcrum pin improve performance?

The HP-2 uses a cold-formed, heat-treated square shoulder fulcrum pin to prevent rotation during pulling. That design minimizes elongation of the rivet hole and reduces the chance of premature tool wear or failure compared with riveters that use round or loosely fitted pins.

• Square shoulder resists pin rotation under load
• Heat-treated steel increases durability and service life
• Reduced hole elongation yields more consistent, secure joints

What makes this riveter comfortable and easy to use?

Ergonomics and material choices help keep repetitive riveting less tiring. The HP-2 pairs thick cushion-molded vinyl grips with a drop-forged carbon steel upper handle to deliver leverage, comfort, and impact resistance for extended use.

• Cushion-molded vinyl grips reduce hand fatigue and slippage
• Drop-forged carbon steel handle provides reliable leverage
• High-strength aluminum alloy body keeps weight down while remaining rugged

How should I maintain and store the Marson HP-2 for long life?

Routine care keeps riveters functioning smoothly and extends working life. Wipe the tool clean after use, periodically lubricate moving joints, and store in a dry toolbox or case to prevent corrosion and damage to the fulcrum pin and nosepieces.

• Clean swarf and debris from jaws and nosepieces after each use
• Apply light machine oil to pivot points occasionally
• Keep spare nosepieces and jaws on hand for different rivet diameters

Who is this tool for? The Marson Sherman 39000 HP-2 is aimed at professionals and experienced hobbyists who need a dependable hand-operated blind riveter for metal fabrication, automotive trim, HVAC, marine fittings, and general maintenance. If you work with mixed-material assemblies or require repeatable, secure blind rivets in the 3/32"–3/16" range (stainless to 5/32"), the HP-2 delivers durable components, ergonomic handling, and a design that resists common failure modes found in lower-cost riveters.
