Snap hooks (also known as spring hooks) are hooks with a spring-loaded clasp on the end to prevent accidental unhooking of a rope, cord or other target line. Snap hooks are a common but essential component in a wide range of industrial applications, from dog leashes to theater lighting.
With a variety of snap types available, it may not be immediately clear which type is correct for a given application. This page will explore the different types of snapshots and their applications.

The traditional spring hook is probably the most common type. Spring hooks are equipped with durable springs and can be attached securely and quickly to ropes, cables, chains or other cords.
In its most basic form, the spring hook is a roughly question mark shaped metal hook with a hollow section in which the spring loaded closure bar is mounted. There is also a small attachment that grips the spring hook and opens it when pressed with the thumb. After releasing the knob, the gate closes quickly under the action of the spring.
Climbing buckles are metal rings with spring loaded entry points that open quickly to separate components of safety equipment, such as cables or wiring. The only way to open a climbing buckle is to manually push the gate away from the ring. This is a key difference between a climbing carabiner and a more traditional spring-loaded hook - if the spring-loaded door is pushed towards the ring, rather than away from it, the spring-loaded hook can only release the rope or cord it is holding.
For certain applications, heavy-duty snap hooks must be used. These snap hooks are constructed for strength and durability and adhere to strict American National Standards Institute (ANSI) guidelines.
For example, ANSI requires fall protection hardware with a gate rating of at least 16 kN and a tensile load rating of at least 22.5 kN. In other words, the snap gate should be able to withstand a kN force of 3,600 lbs. and the snap itself must be able to withstand a force of 5,000 lbs.
Bolt snaps are like trigger snaps in that they can be easily operated with one hand. The main difference between the two snap types is the unlocking mechanism. Whereas trigger snaps use a lever; bolt snaps use a button that releases the spring-loaded door when pressed.
Bolt snaps tend to be less secure than trigger snaps because unexpected pressure on the release button can cause accidental separation from the rope or strap.
What is a trigger snap? A trigger snap is considered a special type of spring-loaded hook. The distinguishing feature of the trigger snap is the addition of a small lever to the spring-loaded door mechanism. The user of the snap can easily press the lever, which then causes the spring door to retract inward and release the connecting wire. In practice, this means that the quick operator can easily connect or detach the cord with one hand.
Trigger snap fasteners are used for handbags and purses, camera and binocular straps, and other fashion or accessory applications.
Snaps can be used in a variety of industries and applications. Examples of common applications include:
Spring hooks can keep volleyball and tennis nets level and tight. Facility managers at baseball fields can use them to support the net behind home plate. Spring hooks can also be used to secure rifle slings, bird straps, or water skis. The sporting applications for spring hooks are virtually limitless.
There is a wide variety of spring hooks for dog leashes, with varying levels of cost and quality. Factors to consider when selecting a spring hook type for a dog leash include: snap material, swivel eye vs. retention, eye shape and eye diameter.
Whether the awning is retractable or fixed, stainless steel snap hooks and other snap types often provide stable and adjustable support.
Sailors can use snap hooks to attach to anchor chains, trailer safety chains, securing equipment or securing the boat to the dock.
