A snap set in the wrong place, or one with a worn-out socket, has to come out. Removing a snap the obvious way — a screwdriver under the edge and a hard pull — is the way that tears the leather.
Decide what you are saving
Before you pick up a tool, be clear about what survives this job. A set snap is held together by a post that has been rolled over, or flared, inside its partner. You cannot unroll that post. Whatever you drill or cut is finished, so plan on fresh hardware for any half you take apart.
What you are saving is the leather and, with luck, the hole. Those are the parts that cost you time and material. A clean removal lets you set a new snap in the same hole with nothing to show for it. A careless one leaves a stretched, torn opening that no snap will hold in again.
This matters more than people expect when the reason for removal is a worn socket. The socket is held on by the flared end of the cap’s own post, so replacing the socket means drilling that post. The cap comes out with it and does not go back in. Order a complete set, not just the socket.
Why prying is the wrong way of removing a snap
The flare is designed to resist exactly the force you apply when you lever a snap apart. Long before the metal gives, the post pulls against the edge of the hole and the leather gives instead. You end up with the snap out and a hole that is oval, split, or both.
Cutting pliers have the same problem on a smaller scale. The jaws have to bite down into the leather to get under the socket, and they leave a crescent-shaped dent on each side of the hole.
The method that works removes only the flare and leaves nothing pulling on the leather at all.
Removing a snap: drill the flare
Turn the piece over so the decorative cap sits dome down on a folded cloth, with a block of scrap wood underneath. The cloth protects the cap’s face; the wood gives the bit somewhere to go that is not your bench. The socket now faces up, and in its center you can see the rolled end of the cap’s post.
Pick the bit by holding it against that rolled end rather than by number. You want one about the width of the post itself: wide enough to take off the curl, narrow enough that it will not reach the body of the socket. If the point wanders, start with a smaller bit to make a centered dimple, then step up.
Drill slowly with light pressure. Speed and force make heat, and heat scorches leather around the hole. Stop as soon as the rolled lip lets go, which it usually does all at once, coming away on the bit. Drilling deeper does nothing useful and starts to widen the hole in the leather.
Lift the socket off, then press the post back out through the leather the way it went in. If it resists, it is usually because a sliver of the rim is still attached; take one more light pass rather than forcing it.
The stud side is the same job
The stud half is held by an eyelet, not a cap, but the principle does not change. Lay the piece with the eyelet’s flat back down, find the rolled end of the eyelet inside the stud, and drill that flare off with the same care.
Read the hole before you reset
Drop a new post into the old hole and let go. That one test tells you which of three situations you are in.
- It stands upright and snug. Reuse the hole. Set the new snap exactly where the old one was.
- It leans, or the hole has pulled oval. Glue a piece of matching leather to the back, let the adhesive cure fully, and punch through both layers with the correct punch.
- A split runs out from the hole. Stop using that position. A split only grows under load. Mark a new spot on sound leather and start fresh.
If you add a backing piece, watch the total thickness. Every decorative snap we sell is a Line 24 with a 0.25″ (6.35 mm) post, and the post needs to stand about 1/16″ (1.6 mm) proud of the leather before setting. A backing patch added to already heavy leather can take the stack past what that post can reach. Use thin leather for the patch, or skive it, so the post still clears.
A quick check before removing a snap
- Order a complete replacement set. The drilled parts do not go back in.
- Cap dome down on a cloth, scrap wood underneath.
- Bit sized against the post, started dead center.
- Slow speed, light pressure, stop the moment the rim lets go.
- Push the post out. Never pry.
- Test the hole with a new post before you decide to reuse it.
A snap removed this way costs you one set of hardware and five minutes. Pried out, it can cost you the strap. If the snap came out because it kept popping open, why your snap will not stay closed helps you pick the fix, and setting a decorative snap without flattening the cap covers the reset. Replacement hardware is in our decorative snaps range, and the snap fastener entry on Wikipedia explains how the parts lock together.
