SK Snaps
It's a tough world. You need tough snaps.
Durable and sturdy, "SK" snap fasteners are reliably
attached to a wide range of applications. The "SK" snap design uses
the attaching technology of a post assembled ring spring snap system.
The "SK" is compatible with a wide range of applications varying from
apparel to military equipment to automobiles. There are two basic sizes
of the "SK" system. The smaller size is represented by the SK-30. The
larger size is represented by the SK-70 or the SK-50 and the "Lift the
Spot" snap. The SK-50 and the "Lift the Spot" snap differ from the SK-70
series in that a larger diameter post is used to assemble the components.
The SK-50 snap fasteners have special components that expand their application
beyond standard textile fabrics and soft material applications to applications
on hard substrates such as metal, fiberglass, or other similar materials.
The Universal Advantage
The "SK" system is designed for applications requiring
a medium or heavy duty snap fastener. Available with 20 or 24 ligne snap
tops, the base "SK" series snaps is made from base materials of steel
or brass. Depending on aesthetic requirements or function demands, several
metallic and oxidized finishes are available. For multiple stacking of
components on top of each other, "gypsy studs" are available. For applications
on hard surfaces, "screw studs" are an option. If your fastener needs
call for a one-way snap action, UFI offers a specially designed system
that resists unsnap unless tension is applied from a specific direction
(the 'Lift the Spot' snap).
Typical Types of Applications
The "SK"
snap is right for products requiring a medium to heavy tension snap fastener.
Typical applications are light, medium and heavy woven fabrics and soft
and hard materials. Examples include: outerwear,
sportswear, sports and athletic equipment, military apparel and equipment,
automotive, aerospace, marine, and industrial applications.

| Correct: The fastener should be snug against
the garment and parallel with the fabric foundation and it's fastening
component |
| Loose: The product is loose on the application
and can be easily pulled off the garment. This can be caused by
several conditions: machine set-up, incorrect application pressure,
compatibility of the fastener system with application. |
| Uneven: The two halves of the fastener
component are not parallel to each other, making the attachment
weak and compromised. This is a result of inconsistent foundation
thickness, variations of the garment construction or the attaching
equipment. |
| Seams: If the fastener is attached on
a stitched seam, it may cut the thread thus compromising the integrity
of the seam. |
| Thick Applications: Excess foundation
thickness can cause weak attachments resulting in low pull off values.
Thin applications can also have the same affect. |
| Always consult your UFI representative or contact
UFI's field technical service (FTC Dept.) for recommendations regarding
product applications and preferred equipment. |
