3. Installation Instructions
Follow these steps to properly install the Prym snap fasteners. A basic understanding of hand tools may be beneficial.
Step 1: Identify Components
Each snap fastener consists of four main parts: the cap (decorative top), the socket (spring-loaded female part), the stud (male part), and the parker screw. The set also includes a plastic mounting tool to aid in assembly.

Step 2: Prepare the Material
Determine the exact location for the snap fastener on your fabric or material. Use an appropriate tool (e.g., an awl or punch, not included) to create a small hole if necessary, ensuring it is suitable for the snap's post. For the screw-in stud, mark the screw location on the rigid surface.
Step 3: Attach the Snap Cap and Socket
Place the cap on one side of the fabric and the socket on the other, aligning them through the prepared hole. Use the provided mounting tool to securely crimp the cap and socket together onto the fabric. Place the cap face down on the tool's base, position the fabric and socket, then use the other part of the tool (or a hammer with the tool) to apply even pressure until the parts are securely joined.

Step 4: Install the Stud with Parker Screw
For the other side of the snap, typically on a rigid surface like wood or plastic, position the stud and screw it into place using the parker screw. Ensure the stud is firmly attached and aligned with the previously installed cap and socket.
Step 5: Test the Fastener
Once both parts are installed, connect them to ensure a secure and functional snap. The snap should engage and disengage smoothly.
4. Usage
These snap fasteners are designed for secure attachment and detachment. To open, pull firmly but gently on the material near the snap. To close, align the cap and stud and press them together until you hear a distinct click, indicating a secure connection.
5. Maintenance
Care Instructions:
- Machine washable at 95 °C.
- Do not bleach.
- Dry cleaning with perchloroethylene or heavy gasoline is permissible.
- Iron at moderate temperature.
- Tumble dry at normal temperature.
Regular cleaning according to these instructions will help maintain the longevity and appearance of the fasteners. Avoid harsh chemicals that may corrode the brass material.
6. Troubleshooting
Snap does not hold securely:
- Ensure both parts of the snap (cap/socket and stud/screw) are correctly installed and fully crimped onto the material or screwed into the surface.
- Verify that the stud is firmly screwed into its base and not loose.
- Check for any debris or damage within the snap mechanism that might prevent a secure connection.
Difficulty in snapping/unsnapping:
- Ensure proper alignment of the cap and stud before pressing them together.
- If new, snaps may be stiff initially; they should loosen with regular use.
- Avoid excessive force, which can damage the snap or the surrounding material.
