GUFERO snap hooks are steel eyes used as a reliable safeguard. The snap hook is closed by a spring mechanism which safely secures the snap hook. GUFERO snap hooks are used in a number of applications and industries.

Application of snap hooks

Among the most well-known applications for snap hooks are mountain climbing and yachting but snap hooks can be used nearly everywhere. Snap hooks are used by rescuers and are found in a number of applications involving work at heights. You can use snap hooks every time you need to make a connection or to secure or attach any industrial component which needs to be taken down.

The following is a list of applications where snap hooks are used:

• snap hooks for mountaineering
• snap hooks for yachting
• snap hooks for rescuers
• snap hooks for securing sails
• snap hooks for lifting cranes
• snap hooks for connecting chains
• snap hooks for connecting steel ropes

Design of snap hooks

The GUFERO snap hook consists of several sub-components. The main load bearing element of the snap hook is the body, which is coiled round steel. The snap hook is interrupted in one place which contains a catch. The catch allows the snap hook eye to open enabling the load or ropes to be hooked into the snap hook. Some snap hooks, especially snap hooks where a higher level of safeguarding is required, can have a locking piece in the shape of a nut. The locking piece is pulled over the connection between the catch and the remaining part of the snap hook thereby preventing the snap hook opening. To open the snap hoop it is necessary to unscrew the nut again.

snap hooks and their types

• Type-A snap hooks - This type of snap hook is designed especially for mountaineering.
• Type-B snap hooks - Basic version of a snap hook. These types of snap hooks are available in our GUFERO order system.
• Type-D snap hooks - snap hooks intended for textile knots, which includes express knots.
• H-type snap hooks - This type of snap hook is pear-shaped in appearance and is designed to bind a half sailing knot.
• Type-K snap hooks - This type of snap hook is especially designed for mountaineers as it has a larger gap.
• Type-X snap hooks - These snap hooks have an oval shape and have the highest strength as the snap hook is always loaded in the longitudinal direction.
• Type-Q snap hooks - The nut snap hook, also called Maillon quick link is always equipped with a catch in the shape of a cap nut. This type of snap hook is also available in our GUFERO order system.

GUFERO eyeless snap hooks

This type of snap hook is available in our order system. The manufacture of this type of snap hook is subject to the DIN 5299 standard. The snap hook has an oval shape tapered towards the place where a rope is attached to the snap hook. This type of snap hook is not equipped with a locking nut. It is therefore necessary to exercise great care when handling the snap hook in order to avoid unintentional disconnection. GUFERO eyeless snap hooks are zinc plated, however stainless-steel versions are also supplied for more demanding applications. We can supply snap hooks with round steel diameters of 4 - 12 mm. The available lengths range from 40 - 140 mm.

GUFERO eyed snap hooks

GUFERO eyed snap hooks are similar to eyeless ones. The main difference between these two types of snap hooks is the added eye which is intended for pulling through a rope. Due to this the snap hook does not rotate when disconnected or reconnected. Unfortunately, this type of snap hook is only available in the zinc plated version. The DIN 5299A standard is applicable to the manufacture of this type of snap hooks. Eyed snap hooks are available in the same dimensions as the eyeless snap hooks.
