Quick answer
Choose tubular rivets for a permanent, industrial-strength bond on open-access strap ends. Choose Chicago screws when you need a removable fastener that sits flush with the leather, especially on bags with closed-end zippers.
Permanent vs. removable: the core trade-off
The biggest difference between these two fasteners is whether you can take them apart later. Tubular rivets are set permanently with a peening tool and mallet — once installed, they stay. Chicago screws have two threaded pieces that screw together by hand, so you can remove and reattach them as needed.
This makes Chicago screws ideal for straps on bags with a closed-end zipper across the top, where you cannot access the inside to set a rivet. Tubular rivets work best when you have full access to both sides of the strap and want a connection that will never loosen.
Strength and durability differences
Tubular rivets from Klum House come in packs of 100 and are made of industrial-strength metal. They create a very strong, permanent bond that holds up to heavy daily use. Chicago screws, sold in packs of four, also provide a strong hold but rely on threaded tension — they can theoretically loosen over time if not checked.
For high-stress areas like bag handles or shoulder strap attachments, tubular rivets offer more long-term security. For lighter-use straps or decorative attachments, Chicago screws are plenty strong and much easier to install.
Tubular rivets vs Chicago screws: trade-offs at a glance
- Installation: Tubular rivets require a peening tool and mallet. Chicago screws install by hand — no tools needed.
- Permanence: Tubular rivets are permanent once set. Chicago screws are fully removable and reusable. If you might need to replace a strap later, choose Chicago screws.
- Strength: Tubular rivets create an industrial-strength permanent bond. Chicago screws rely on threaded tension and are strong but can loosen over time.
- Flush fit: Chicago screws have flat heads on both ends and sit flush with the leather. Tubular rivets have a visible cap on one side and a formed head on the other.
- Quantity and cost: Tubular rivets come in packs of 100 for $13.80. Chicago screws come in packs of 4 for $2.38. For a single strap attachment, Chicago screws cost less upfront. For multiple projects, tubular rivets offer better per-unit value.
