Choosing leather hardware, patterns & care supplies often comes down to one practical fork: do you need Chicago screws for binding work, or snap fasteners for a press-stud closure? The four choices below split again between single-format hardware and assorted sizes. Start with the fastening style, then use the matrix to narrow the choice by finish, quantity, tools, and listed price.
Quick take
First separate the fastening family. Chicago screw choices are for screw-based binding; snap choices are for press-stud work. Then ask whether you need one stated screw format, several lengths, brass buttons, or metal buttons with tools. That short path keeps the comparison practical: the right kit is the one whose listed format matches the project.
Listed-price comparison
The listed prices run from $10.39 to $25, an absolute spread of $14.61. The table keeps price separate from the hardware decision, so the bars provide a quick view of where each choice sits.
| Product | Listed price | Price bar |
|---|---|---|
| Brass-plated Chicago screw lot | USD 25.00 | |
| Assorted Chicago screw kit | USD 13.49 | |
| Brass snap fasteners kit | USD 10.39 | |
| Metal snap fasteners kit | USD 13.45 |
Decision matrix
- Single-format Chicago screws: Match the 100-piece brass-plated lot when one stated post length fits the job. The trade-off is a single format rather than an assortment.
- Several Chicago screw lengths: Match the 80-set assorted kit when different post lengths matter. The trade-off is that the quantity is distributed across five sizes.
- Brass snap buttons: Match the brass kit with four tools when brass buttons and mixed colors suit the project. The trade-off is the mixed-color presentation.
- Metal snap buttons: Match the metal kit with four tools when metal wording fits the brief. The trade-off is that its title uses metal wording rather than the brass wording of the other snap kit.
Product notes
Leather Hardware - LOT Of 100 BRASS PLATED Chicago Screws - 3/8

The appeal of this lot is its clearly defined run: 100 brass plated Chicago screws with 3/8\" posts and 7/16\" caps. A threaded hole in the center identifies the Chicago-screw format, while the material is listed as metal. It suits a leather bag project that calls for matching screw hardware in one stated size. Its limitation is format flexibility: the lot is presented only as 3/8\", rather than a range of post lengths. It also addresses screw-based binding, not snap-button fastening, so it is a focused hardware purchase.
80 Sets Chicago Screw Leather Rivets Assorted Kit Chicago Binding Screws 5 Sizes

Projects that need sizing variety point to this 80-set Chicago screw kit. It divides the set across five post lengths-1/4, 3/8, 1/2, 9/16, and 11/16 inch-with 16 sets for each size, and the clear partitioned storage box keeps the sizes separated. The carbon steel material and Chicago binding-screw format are stated plainly. The trade-off is that the 80 sets are distributed across five sizes, not concentrated in one length. The kit is devoted to screw hardware, so it does not cover snap fasteners.
Leather Snap Fasteners Kit 10/12/15mm Brass Button Snaps Press Studs With 4 Tool

A brass-button focus makes the kit a useful match for projects where the hardware material matters. The set covers 10mm, 12mm, and 15mm snap sizes and includes four steel installation tools; its button colors are described as bronze, silver, grey, and golden. That combination suits leather, canvas, bags, jackets, and other craft uses. The limitation is the mixed-color format: it is not a single stated finish, so a project requiring one consistent appearance may call for a different choice. It is also snap hardware, not Chicago screws.
Leather Snap Fasteners Kit 10/12/15mm Metal Button Snaps Press Studs With 4 Tool

For shoppers who want snap hardware described simply as metal, this kit includes four installation tools and the same 10/12/15mm size range named in its title. Its round button-snap format is described for leather, canvas, bags, jackets, and upholstery work. The useful distinction is wording: unlike the brass-button kit, this title identifies the snaps as metal rather than brass. That is the limitation for a brass-specific brief, even though the included tools and size range support a similar kind of craft task.
Final recommendation by use case
- For one stated Chicago screw format: choose the brass-plated Chicago screw lot.
- For several screw lengths in one assortment: choose the assorted Chicago screw kit.
- For brass snap buttons and a mixed-color kit: choose the brass snap fasteners kit.
- For metal snap fasteners with four tools: choose the metal snap fasteners kit.
The practical rule is simple: start with Chicago screws or snaps, then decide whether the listed size format and finish fit the project. The brass snap kit is the lowest-priced entry in the table, while the 100-screw lot is the highest-priced; that $14.61 spread is meaningful only after the fastening style is right. For leather bag hardware, the Chicago screw pair serves binding-focused work, while the snap pair serves press-stud-focused work.
