SW Snaps

Parallel spring snaps set the standard all over the world.

"SW" parallel spring snap fasteners are popular around the globe. UFI's parallel spring snap fastener features a smooth consistent snap action with the reliability of a post attachment, enchanced by a wide range of optional tops and finishes. "SW" snap fasteners are the definitive choice for quality manufacturers of performance apparel and accessories.

Parallel spring snap fasteners achieve their unique snap action from the mechanical advantage created through a wire-formed spring inserted into a slotted bowl-shaped socket. Because of the socket's design with the enclosed spring assembly, the function of the snap is protected from contamination of foreign matter. The result is maximum snap performance under the worst conditions. Whether your garments are subjected to snow, ice, rain or other harsh environments, the "SW" snap system ensures a reliable snap closure each time.

The Universal Advantage

Considerations

Basic applications range over a variety of woven fabric weights and thicknesses. The application of a "SW" fastener on knit fabrics is not recommended in most cases. Post attached fasteners are best suited for applications on woven fabrics.

Attachment

Attachments can be made using a basic footpress, pneumatic footpress, electric flywheel press or a fully automatic Model II attaching machine. Logo designed snap tops can be automatically registered during attachment using an automatic attaching machine specifically designed for this purpose.
