Krenlory A1605 Pneumatic Rivet Set .401" Shank for 1/4" Solid & Round Rivets — Hardened Steel, CNC-Finished

The Krenlory A1605 Rivet Set is a hardened steel, .401" shank pneumatic rivet bit engineered to set 1/4" round, dome and universal solid rivets with precision and durability.

Built for mechanics, sheet-metal workers, boat restorers and hobbyists who use air hammers, the Krenlory A1605 delivers a reliable, repeatable seating action for solid rivets. CNC-machined and quenched for toughness, this rivet set mates to common .401" shank air hammers and pneumatic rivet guns so you can use the power tools you already own. Its mirror-polished round head seat reduces marring and concentrates force evenly for cleaner, professional-looking rivet finishes.

How does this rivet set work with my existing air hammer?

The A1605 uses the industry-standard .401" shank so installation is straightforward—push into the tool, secure the retainer and you're ready to rivet. Its dimensional accuracy from CNC finishing ensures a snug, wobble-free fit that transmits impact force efficiently.

• Standard .401" shank fits most air hammers and pneumatic rivet guns
• Quick-change retainer allows fast removal and replacement
• CNC tolerances minimize play and improve strike alignment

What rivet types and sizes can I set with the A1605?

This bit is tailored for 1/4" (6.35 mm) solid rivets including round head, dome and universal styles commonly used in marine, automotive and metal fabrication work. It supports aluminum and steel rivets when used with appropriate rivet materials and fastener selection.

• Designed for 1/4" solid and round-head rivets
• Works with dome and universal head rivets found in boats and aircraft panels
• Compatible with steel and aluminum rivet materials depending on application

What makes this rivet bit durable and reliable?

Krenlory manufactures the A1605 from solid carbon steel, then quenches and CNC-finishes each piece to achieve high hardness and dimensional accuracy. The result is a tool that resists deformation under repeated impact and stands up to heavy-duty shop use.

• Solid carbon steel construction for high impact resistance
• Quenched and CNC-machined for lasting hardness and precise fit
• Mirror-polished seat to reduce scarring on rivet heads

How fast and easy is it to change rivet sets on the tool?

Changing the A1605 is a simple, tool-free procedure: loosen the retainer a few turns, compress the spring, and withdraw the bit. This quick swap approach keeps downtime low during multi-rivet jobs or when switching sizes.

• Simple unscrew-and-pull replacement method
• Spring-assisted ejection speeds bit removal
• Minimal setup time for production or repair tasks

Who is this for? The Krenlory A1605 is aimed at professional technicians and serious DIYers who need a dependable rivet-setting solution for 1/4" solid rivets. If you perform boat hull repairs, aircraft skin work, motorcycle and automotive body riveting, or general metal fabrication and require a rugged, precision bit that fits standard .401" air hammers, this set is built to meet those demands. Krenlory backs the product with a 30-day return policy and a 12-month warranty for added peace of mind.
