Choosing leather hardware, patterns & care supplies often comes down to one practical trade-off: do you need one repeatable Chicago-screw format, or an assortment that can cover different builds? These two options take opposite approaches. One is a 100-piece brass-plated lot in a specified size; the other packages 80 sets across five lengths. The useful decision is less about a generic winner and more about matching the hardware format to your project.

Pick 80 Sets Chicago Screw Leather Rivets Assorted Kit Chicago Binding Screws 5 Sizes when different post lengths and separated storage matter.

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

The clearest reason to choose this lot is its defined hardware format: the post is specified as 3/8 inch, the cap as 7/16 inch in diameter, and the center has a threaded hole. Those details give a project concrete dimensions to work around, while the 100-piece quantity suits repeated use of the same screw. The brass-plated finish is another useful part of its product profile. Its limitation is the narrower sizing approach: the lot is presented around one post length, unlike the assorted kit. Choose it when the stated dimensions match your pattern; the single-format design is less suitable when varied lengths are central.
80 Sets Chicago Screw Leather Rivets Assorted Kit Chicago Binding Screws 5 Sizes

Choose this kit when one leather project may call for different post lengths. It includes five sizes, with 16 sets allocated to each, and the clear storage box partitions the components by size. The post lengths run from 1/4 inch through 11/16 inch, and the post diameter is 3/16 inch or 5 mm, useful planning details when a pattern specifies a measurement. The limitation is the split quantity: each length has its own allotment, so this is not a single-format bulk lot. It uses steel and is intended for repeated use, but neither detail alone determines which kit suits your project. Choose it for range and organized storage.
Final choice by use case
- For repeat builds with one fixed screw specification: choose Leather Hardware - LOT Of 100 BRASS PLATED Chicago Screws - 3/8.
- For patterns that call for different post lengths: choose 80 Sets Chicago Screw Leather Rivets Assorted Kit Chicago Binding Screws 5 Sizes.
