Our take on the Open Back Screw Posts

Open back screw posts are two-piece Chicago-style fasteners whose post extends past the cap, so they clamp layered leather and mixed materials without an exact post length match. The threaded halves unscrew and reattach, which suits adjustable straps, cases, belts and repair work. Iron construction keeps them sturdy but means they can rust if left wet. Compared with standard Chicago screws, the open back gives more slack for uneven stacks; compared with rivets, they come apart again.

About the Open Back Screw Posts

Open Back Screw Posts, also called Open Back Chicago Screws, are two-piece fasteners for leathercraft. They suit a wider range of material thicknesses than standard Chicago screws.

The open-back construction lets the post extend beyond the cap. This makes it easier to secure layered leather or mixed materials without an exact post length match.

The threaded design lets you take parts apart and reattach them. Use them for adjustable straps, cases, belts and repair work.

Questions and answers

What is the difference between open back and standard Chicago screws?
The post on an open back screw extends beyond the cap, so it fits a wider range of material thicknesses. Standard Chicago screws need a closer post-length match to the stack.
Which length should I pick for my leather?
The 1/8-inch post has a 0.13 in. (3.2 mm) post and 0.22 in. (5.5 mm) screw; the 1/4-inch has a 0.25 in. (6.4 mm) post and 0.28 in. (7.1 mm) screw. Measure your layered stack and choose the shorter post that still passes through.
Can I take them apart and reuse them?
Yes. The threaded design lets you unscrew the halves and reattach components, which suits adjustable straps and repair work.
Will iron screw posts rust?
Iron can corrode when exposed to moisture. Keep them dry and consider a protective finish if the project will see damp use.
What comes in the pack?
The pack is a 10 count of screw posts in the length you choose, with coarse threading.
Where is the Open Back Screw Posts cheapest?
At Tandy Leather, Inc., for $4.99, as of our latest check.
