Grivel listened to all the feedback from their initial release of the 360 ice screw and came back with an improved solution. For the newest version of the 360 ice screw (out now!) Grivel updated the hanger for improved racking, fixing the biggest complaint of the previous 360. This was an interesting problem to solve because one of the screw’s most known and liked features was how it fit into really tight and narrow placements. Grivel had to balance lengthening the hanger to rack better while still keeping the profile as small as possible. The functionality of the screwing arm did not change at all and still is one the longest arms on the market, for maximum cranking.

Grivel says the 360 screw is now the fastest ice screw to place because they added sharper and longer teeth (teeth 25% longer than other Grivel screws) providing extra grip on the first quarter-turn into the ice. Yes, this also means the teeth are more fragile, so they won’t survive bottoming out as well as another screw might.

Perhaps the most unique feature, found on all Grivel ice screws, is their “reverse threading.” This means that the screw threads are angled in the opposite direction of most other brands of ice screws. Another way to think of it is: Grivel screw threads are flipped down from traditional threading.

Reverse Threading versus Traditional Threading Ice Screws

Grivel believes reverse threading makes a significant difference (so does Cassin/CAMP). The example Grivel touts is from a concrete pull test. The UIAA normally tests ice screws using a straight pull from a specific mix of concrete to test things like hanger strength. During these pull tests, Grivel’s reversed threads grabbed more concrete than the more standard thread design. Presumably, this larger chunk of concrete would be akin to a larger area of ice, suggesting that the screw was more effective at spreading the load.

Further: If you are interested in the merits of the “reverse thread” design, check out other internet posts to see photos of the concrete tests and read about the concerns of testing in concrete. Or read discussion of the engineering that goes into thread design, or the questioning of straight pulls while testing to judge if reverse threading would make a [significant] difference in the event of a fall on ice. All the while remembering that while out ice climbing the #1 rule is: Do Not Fall.

In the end, it’s nice to see the screws priced similar to others in the market ($69.95). Reverse threading or not, the sharper bite, narrow hanger head, and long cranking arm are enough to make it worth consideration. Grivel screws come in three color-coded sizes, short (red, 12cm), medium (black, 16cm) and long (yellow, 20cm).
