Choosing leather hardware, patterns & care starts with the project, not the price. Do you need a snap for thicker leather, a fastener for straps and bags, threaded screws for an assembly, or a template to shape a shoulder bag? These four choices serve distinct jobs, so the most useful shortcut is to match the format to your work first and use price as the tie-breaker.
Quick take
- For snap fasteners: Compare the Black Line 24 and Black Line 20 formats according to leather thickness and post style.
- For screw-together hardware: The 100 brass-plated Chicago screws are the dedicated choice.
- For pattern work: The DIY shoulder-bag template is the only choice focused on shaping a project rather than attaching hardware.
Listed-price comparison
Prices span USD 25.00 to USD 55.95, a USD 30.95 difference between the lowest and highest choices. Both snap sets share the USD 55.95 price, while the Chicago screws and shoulder-bag pattern sit lower in the range.

Decision matrix
- Thicker leather fastening: Select the Black Line 24 snap format, whose stated post is intended for 8-10 oz leather.
- Mixed leather thicknesses for everyday projects: Choose the Black Line 20 set, which combines regular and short posts for the ranges described.
- A threaded attachment with a defined quantity: Choose the brass-plated Chicago screws, with 100 pieces in the lot.
- A shoulder-bag outline or stencil: Choose the kraft-paper DIY sewing pattern, which is identified as template only.
- Price-first selection: The Chicago screws are the lowest-priced choice, followed by the shoulder-bag pattern; the two snap sets tie at the highest listed price.
Product notes
Black Line 24 Snaps
This set fits a project that specifically calls for Line 24 snaps and a 5/16-inch post. The post is intended for thicker 8-10 oz leather, while the 19/32-inch cap completes the named snap format. Its 100-pack quantity suits a run of matching fastening jobs, and the black finish is part of the product name. The limitation is format specificity: a design calling for Line 20 snaps or Chicago screws needs a different hardware choice. It is also a fastening component rather than a pattern, so it will not help with laying out a shoulder bag. Pick it when the leather thickness and snap format line up with the project.
Black Line 20 Snaps
Black Line 20 Snaps combines regular and short posts in one hardware choice. The regular post is 3/16 inch, while the short post is 1/8 inch; the stated ranges are 5-7 oz and 4-5 oz leather respectively. That makes the set relevant to straps, bags, belts, holsters, and everyday leatherwork where post length matters. A 100-pack supports repeated fastening work. Its limitation is that both formats remain Line 20 snaps: a project specified around Line 24 hardware or Chicago screws calls for a different solution. It also addresses fastening only, not the pattern layout or stencil stage of bag making.
100 Brass-Plated Chicago Screws
The Chicago screw lot is the straightforward choice when the project calls for threaded hardware rather than snap fasteners. It contains 100 brass-plated screws with a 3/8-inch post, a 7/16-inch cap diameter, and a threaded hole in the center. Those named dimensions give the project a clear hardware format to work around. The limitation is just as concrete: this is a screw lot, not a Line 20 or Line 24 snap set, and it does not provide a shoulder-bag pattern. The brass-plated metal finish is part of the product description, making this a focused hardware purchase for leather assemblies that use Chicago screws.
DIY Shoulder-Bag Leather Craft Pattern
Start here when the main task is shaping a shoulder bag rather than attaching hardware. The item is a DIY sewing pattern made as a kraft-paper drawing stencil for leather handcraft, and it is identified as template only. That makes it useful for planning a shoulder-bag outline before cutting or sewing. The limitation is that the template does not supply snaps, Chicago screws, or other fastening components, so it cannot replace a hardware purchase. It is also focused on shoulder bags rather than a general fastener need. Choose it when the project needs a physical pattern guide and the hardware decision comes separately.
Final recommendation by use case
For a thicker-leather snap job, choose Black Line 24 Snaps. For straps, bags, belts, or holsters where regular and short posts are useful, choose Black Line 20 Snaps. For threaded leather hardware in a 100-piece lot, choose 100 Brass-Plated Chicago Screws. For shoulder-bag pattern work, choose the DIY Shoulder-Bag Leather Craft Pattern. If price determines the decision, the Chicago screws are USD 25.00, the pattern is USD 31.91, and each snap set is USD 55.95.
