Screwgate Carabiner: our selection for climbing and mountaineering
The screwgate carabiner provides a dependable manual locking system, ideal for anchors, lanyards, or belay stations. Essential in climbing, mountaineering, or via ferrata, it remains effective even in the harshest conditions.
Safety Screwgate Carabiner
Designed for a secure screw closure and high major-axis strength, this carabiner ensures reliability and long-term durability.
HMS and Directional Carabiners
- HMS carabiner: large pear-shaped design, perfect for belaying with a Munter hitch.
- Directional carabiner: guides the rope along the load axis to prevent cross-loading.
- Unidirectional carabiner: minimises unwanted movement for enhanced safety.
Type B Screwgate Carabiner
The Type B screwgate carabiner corresponds to the most versatile standard shape, suitable for most climbing and mountaineering applications. More compact than an HMS carabiner, it offers better control of positioning and reduced bulk, while maintaining high major-axis strength for belaying and key connections.
Strength and Materials
The strength of a carabiner depends on its load-bearing axis and the material used:
- Major axis closed: 20 to 30 kN (2000 to 3000 kg).
- Minor axis: 6 to 10 kN.
- Gate open: around 7 to 10 kN.
Aluminium carabiners combine lightness and versatility. Steel models, though heavier, often exceed 40 kN and are ideal for intensive use. Regular inspection for wear ensures lasting safety.
FAQ
What’s the difference between a screwgate and an auto-locking carabiner?
The screwgate carabiner offers precise manual locking, ideal for cold or exposed environments. The auto-locking carabiner, on the other hand, locks automatically upon closure, making it perfect for quick belaying at the crag or in indoor climbing gyms.
What strength should you look for in a screwgate carabiner for climbing and mountaineering?
For sport climbing, multi-pitch routes, or mountaineering, a screwgate carabiner with 22 to 25 kN major-axis strength provides sufficient safety for belaying and anchors. For more demanding or frequent use, a stronger model will improve durability and resistance to wear.
When should you use a screwgate carabiner instead of a non-locking one?
A screwgate carabiner should be used whenever a secure locking mechanism is essential, particularly at anchors, for belaying, or fixed protection points. It reduces the risk of accidental gate opening and secures critical points in climbing, mountaineering, or via ferrata.
To choose the right carabiner for your needs with confidence, it’s important to understand the differences between models, their locking systems, and their specific uses. To learn more and make an informed purchase, check out our guide to the different types of carabiners.
