How to Set a Popper Snap Using a Snap Setter Tool & Anvil
Setting popper snaps (also known as press studs or snap fasteners) is an essential skill for any leather crafter or sewing enthusiast. Whether you're creating leather bags, garments, accessories, or craft projects, properly installed snaps provide both functional fastening and a professional finish. In this comprehensive guide, we'll walk you through the process of setting popper snaps using a snap setter tool and anvil, with particular reference to the Popper Snap Setter Tool from British Leather Supplies.
What You'll Need
Before you begin, gather the following materials and tools:
Essential Equipment
Snap Setter Tool Kit – The British Leather Supplies popper snap setter includes a line snap setter (11 cm in length) and an anvil (2.5 cm diameter). This tool is specifically designed for setting 13 mm and 15 mm head size popper snaps.
Popper Snaps – Choose quality snaps such as solid brass poppers. A standard four-piece popper snap consists of:
- Cap (top visible piece with male component)
- Socket (top piece with female component)
- Stud (bottom male piece with post)
- Post or backing piece (bottom piece that attaches to the stud)
Leather or Fabric – Your project material, properly marked where the snap will be positioned
Mallet or Hammer – A leather mallet or small hammer for striking the setter tool
Hole Punch or Awl – For creating precise holes in your material (typically 2-3 mm depending on snap post size)
Cutting Mat or Protective Surface – To protect your work surface
Ruler and Marking Tool – For accurate placement
Understanding Popper Snap Components
Before you start setting snaps, it's important to understand how the four pieces work together:
The cap and socket form the visible top layer. The cap typically has a raised centre (male component), whilst the socket has a recessed centre (female component) that receives the cap when fastened.
The stud has a long post that passes through your material from underneath, and the backing piece secures it from the top.
When properly set, the cap and socket pieces will sit on opposite layers of material (for example, on either side of a bag flap), and when pressed together, they create a secure closure.
Step-by-Step Guide to Setting Popper Snaps
Step 1: Mark Your Snap Placement
Accurate placement is crucial for properly functioning snaps. Using a ruler and marking tool, carefully mark where you want your snaps positioned. If you're setting multiple snaps, ensure they're evenly spaced and aligned.
Top tip: Always test the placement by temporarily folding or closing your project to confirm the snaps will align correctly before making any holes.
Step 2: Create the Holes
Using a hole punch or awl, create a small hole at each marked position. The hole should be just large enough for the snap post to pass through – typically 2-3 mm. If the hole is too large, the snap will be loose and may not hold securely.
For leather, a rotary punch works brilliantly. For fabric, you may use a small awl or sharp scissors to create a clean opening.
Step 3: Insert the Stud Component
Take the stud piece (the one with the longer post) and push it through your material from the underside so the post protrudes through to the top side. The decorative cap of the stud should sit flush against the bottom of your material.
Step 4: Position the Setter and Anvil
This is where your snap setter tool comes into play:
Place the anvil (the 2.5 cm diameter piece from your British Leather Supplies kit) underneath your work, positioned directly beneath the stud you've just inserted. The anvil should have a small indentation or cup that cradles the rounded bottom of the stud.
Now take the cap or socket piece (depending on which half you're setting) and place it over the protruding post of the stud, with the decorative side facing up.
Position the setter tool (the 11 cm line snap setter) on top of the cap or socket piece. The end of the setter should fit snugly over the snap component.
Step 5: Strike and Set
Hold the setter tool firmly in place, keeping it perpendicular to your work surface. Using your mallet or hammer, strike the top of the setter tool with one or two firm, deliberate blows. You should hear and feel the snap components crimp together.
Important: Don't strike too hard or repeatedly, as this can damage the snap or deform the metal. One or two solid strikes should suffice.
Step 6: Check Your Work
Remove the setter tool and examine the snap. The cap or socket should be securely attached to the stud, with no wobbling or loose components. The decorative top should sit flat and smooth against your material.
Step 7: Repeat for the Matching Half
Now repeat steps 3-6 for the opposite side of your closure (the other layer of material), ensuring you use the matching component. If you set a cap on one side, you'll need to set a socket on the other, and vice versa.
Critical tip: Before setting the second half, test the alignment by closing your project. You can temporarily hold the second snap in place to ensure perfect alignment before making it permanent.
Professional Tips for Perfect Results
Prepare Your Materials
If you're working with thick leather, consider thinning the areas where snaps will be set using a skiving knife or edge beveller. This helps the snap sit more flush and reduces bulk.
Practice First
Before setting snaps on your final project, practise on scrap material. This helps you gauge how much force is needed and ensures you're comfortable with the process.
Work on a Stable Surface
Always work on a solid, stable surface. A wobbly table or uneven surface can result in poorly set snaps.
Keep Components Organised
Separate your caps, sockets, studs, and posts into different containers. It's surprisingly easy to mix them up, which can lead to frustrating mistakes.
Check Alignment Constantly
Misaligned snaps are one of the most common mistakes. Always double-check that opposing snaps will meet correctly before setting them permanently.
Match Your Tools to Your Snaps
The British Leather Supplies snap setter tool is designed for 13 mm and 15 mm snaps. Using the wrong size tool can damage both the snap and your project. Always verify compatibility before beginning.
Common Mistakes to Avoid
Holes Too Large – If your hole is too big, the snap will be loose and may pull through the material. Always err on the side of a smaller hole, as you can carefully enlarge it if needed.
Insufficient Force – If you don't strike hard enough, the snap components won't properly crimp together and will come apart with use.
Excessive Force – Conversely, striking too hard can deform the snap, crack the material, or damage the decorative finish.
Misalignment – Take time to ensure your marks are accurate and that opposing snaps will meet correctly.
Wrong Component Pairing – Make sure you're setting matching pairs (cap with socket). Setting two caps or two sockets won't work!
Caring for Your Snap Setter Tool
Your British Leather Supplies snap setter tool is built to last, but proper care will extend its lifespan:
- Clean the tool after each use to remove any leather debris or metal filings
- Store the setter and anvil in a dry place to prevent rust
- Keep the striking surface clean and smooth
- Occasionally apply a light coating of oil to prevent corrosion
When to Use Popper Snaps
Popper snaps are incredibly versatile and suitable for numerous applications:
- Leather goods: bags, wallets, pouches, and belts
- Garments: shirt cuffs, nappy covers, baby clothes, and jackets
- Accessories: watch straps, pet collars, and camera straps
- Home décor: cushion covers, removable upholstery, and fabric bins
The British Leather Supplies popper snap setter works particularly well with solid brass popper snaps, which offer excellent durability and an attractive finish that complements high-quality leather projects.
