Leather Hardware, Patterns & Care: Choose Snaps or Chicago Screws by Project

Choosing leather hardware, patterns & care gets easier when you match the fastening method and leather thickness first. Compare Line 24 and Line 20 snaps, Chicago screws, and a boxed repair kit by project use.

Last updated Aug 25, 2026

Choosing leather hardware, patterns & care usually turns on two practical questions: do you need a snap closure or a screw-fastened connection, and what thickness range suits the leather? The four choices here split across those decisions. Start with connection style, then use the stated leather guidance and included accessories to narrow the field.

Quick take

The fastest route is to separate snap hardware from Chicago screws first. Among the snap choices, the two Black Line formats are organized around different leather-use cases, while the 70 Sets kit adds a storage box and manual installation tool for repair work. The Chicago screw lot serves a different connection style. Price is a secondary tie-breaker: the comparison spans a $42.96 gap, but cost does not change how the hardware is used.

Listed-price comparison

The two Black Line snap choices share the same listed price, while the Chicago screw lot and boxed snap kit occupy lower points in the comparison. The price bars show relative listed prices only; they do not indicate suitability or performance.

Decision matrix

  • Thicker leather in the 8-10 oz range: Black Line 24 Snaps, with its 5/16-inch post and Line 24 format.
  • Regular and thinner leather work: Black Line 20 Snaps, which combines regular and short posts for the stated 5-7 oz and 4-5 oz ranges.
  • A threaded connection: 100 Brass-Plated Chicago Screws, specified with a 3/8-inch post and threaded hole.
  • Repair work with setup pieces included: 70 Sets 15mm Snap Fasteners Kit, which includes snap components, a storage box, and a manual installation tool.

Product notes

Black Line 24 Snaps

Black Line 24 Snaps 5/16" Post & 19/32" Cap - Leathercraft Hardware - SLC

The 5/16-inch post and 19/32-inch cap make this a focused choice for thicker leather: the description places it in the 8-10 oz range and calls the Line 24 fasteners heavy-duty. That is the clearest reason to choose it for firm or multi-layered leatherwork. Its limitation is specialization: the listed post is tied to that thicker use case, so it is less directly aligned with projects centered on the thinner ranges described for Line 20. The USD 55.95 price also matches the highest listed price in the comparison. Choose it when the project brief specifically points to Line 24 hardware and thicker leather.

Black Line 20 Snaps

Black Line 20 Snaps - Regular & Short Posts - Leathercraft Hardware - SLC

Black Line 20 Snaps are the fitting direction when one project list spans regular and thinner leather. The description specifies regular 3/16-inch posts for 5-7 oz leather and short 1/8-inch posts for 4-5 oz leather, with belts, straps, bags, holsters, and everyday work among the examples. Those two post lengths are the concrete reason to choose it. The limitation is that the description calls this line medium-duty, while P1 is the line described for 8-10 oz leather. Its USD 55.95 price also matches P1, so the stated thickness range-not price-should separate the two.

100 Brass-Plated Chicago Screws

Leather Hardware - LOT Of 100 BRASS PLATED Chicago Screws - 3/8

100 Brass-Plated Chicago Screws change the fastening method entirely: the 100-piece lot uses a threaded hole rather than a snap closure. The 3/8-inch post length and 7/16-inch cap diameter give a clear specification for a screw-fastened leather assembly. That defined format is the reason to choose the lot when Chicago screws suit the construction. The limitation is the fixed 3/8-inch post size; a project built around another post length would call for a different specification. At USD 25.00, the lot occupies a middle point between the snap choices and the boxed kit, so connection style matters more than price alone.

70 Sets 15mm Snap Fasteners Kit

70 Sets 15mm 5/8" Snap Fasteners Kit - Metal Snaps for Leather Craft Repair

70 Sets 15mm Snap Fasteners Kit suits repair-oriented shopping when an installation aid and storage are useful. Each set contains two caps, one stud, and one socket, and the box includes a manual snap installation tool. The gun-black metal finish and 15 mm (5/8-inch) cap identify the listed format. The limitation is explicit: the description positions it for light-to-medium fabric and cautions against thick fabric, so it is a less direct choice for the thick-leather use case described for Line 24 hardware. At USD 12.99, it has the smallest listed price, but the lighter-material guidance should lead the decision.

Final recommendation by use case

If the project calls for thicker leather in the 8-10 oz range, choose Black Line 24 Snaps. For a mix of regular and thinner leather work, Black Line 20 Snaps is the more fitting direction because the title covers regular and short posts. Choose 100 Brass-Plated Chicago Screws when the assembly calls for threaded hardware rather than snap action. For repair work where a box and manual installation tool are useful, choose the 70 Sets 15mm Snap Fasteners Kit. The $42.96 spread is worth noting, but fastening method and stated material range are the more important filters.
