Designed for ski mountaineering, glacial travel and high-end alpinism, the Ultralight Ice Screw says it all in the name. Weighing in at 45% lighter than our Express Screws, the Ultralight Screw combines a steel tip with an aluminum body and forged aluminum hanger that features two clip-in points. The innovative wire-gate Express handle shaves more weight and also clicks open and closed. The Ultralights are also easily identified by length with the classic BD color scheme.

Ultralight Ice Screw is rated 4.6 out of 5 by 14.
Rated 5 out of 5 by from excellent Was not initially willing to pay the extra money to step up from BD's steel screw. However, after reading a few reviews, I picked one to try out, and now have a few. I've been really impressed. The updated tooth angle/cutting edge has makes a huge difference. These bite quickly, and are much easier to place especially with the wire gate type "express handle". They are significantly lighter, and have a more user friendly hanger. Great product. I've also appreciated that these are a larger diameter, allowing safer "rebore" of previous holes (Watch the DB QC vid if you haven't) . This is especially advantageous in the CO front range where many climbs get beaten up.

Rated 3 out of 5 by from Gets stuck mid-way I bought these screws a couple of weeks ago and got to try them. They are amazingly light. The handle is great, it has a spring action to come back to its rest place. The teeth are aggressive and dig very fast in the ice. It is almost unbelievable how quickly the screw holds in place. But...for some reason after a few turns, or even midway into insertion, the screw just gets stuck. It halts a bit less suddenly than if you were to hit rock. But it is quite stuck. It takes a lot of force to get it to turn again, to the point that I sometimes think the handle could break. Sometimes I was not able to get it unstuck using the knob, I had to wrap my hand around the screw plate and really put a lot of force to get it moving again. Sometimes it happened 2 or 3 times during the placement of a single screw. In the same ice I placed BD Express screws without any such problem. I am not sure why this is happening. My guess is the type of material allows the water to refreeze on it easily. And the large diameter of the screw (largest I have seen so far) means more surface the ice can grab on.

Rated 2 out of 5 by from Good at times, terrible at others With dry ice these are great. Quick to bite, easy to drill. However in any ice that is wet or has a lot of moisture in it, they will almost certainly have issues getting placed. In wet ice they will often become literally stuck and you cannot place them fully without really hammering on the hanger. I know aluminum screws always have more friction, but these are noticeable worse than my petzl aluminum screws. I'll take the weight of steel screws, at least they can be fully placed in all ice conditions.

Rated 5 out of 5 by from A Good Tool for the Right Job The ultra-light ice screw has its place in climbing, especially if you are hauling them around at high altitude, long distances, or for occasional use. On a day-to-day basis using them for ice cragging isn't an effective use of your money. My pros are obvious: Light weight, sharp as needles when new, nice broad sweeping crank lever. The cons are less obvious: everyone I've spoken to who used these in both Ouray Ice Park and RMNP backcountry noted that at about 4 cms into the ice there is a sudden "binding" or "tight spot". I'm not sure why, but everyone commented. To a beginner this might feel like the screw has "bottomed out", but another quick twist and it starts turning again easily. Overall these screws are what they are advertised and I appreciate that I could afford a few for my longer backcountry trips.

Rated 5 out of 5 by from Light? ya.. but the tooth profile sets them apart Yes, these are insanely light, but the tooth profile is the reason to upgrade to these screws. Out of the box they start significantly better than any other screw on the market. The tooth profile these have starts better than any other screw available, and it has significantly reduces the time to place one of these compared to the old express screw, or any other brand's screw for that matter. To add to the ingenuity of the teeth, they have a pre-set sharpening plane. If "pre-set sharpening plane" doesn't make any sense, what it means is with just a flat file you can fix a dinged up, or dull, tooth in the field with gloves on in a matter of 30 seconds. No more special ice screw sharpening jig in your garage... Even if you don't buy a "full rack", having one or two of the 13s as a screw to place in the more tenuous parts of a given pitch is really convenient and basically adds no weight. I have yet to get a feel for how long these will last, but I'm guessing that will be their only weakness compared to the old express screw.

Rated 5 out of 5 by from Helium Balloons are Jealous The weekend after leading on regular steel BD screws, these arrived. It was an incredible contrast. 16 screws weighed nothing in the pack. They screw in with one turn and are easy to remove. Another group wanted to compare these with the Petzl Laser Light, while the weight seems comparable, the BD ultralights went in much easier.

Rated 5 out of 5 by from Best on the Market I posted a review after first getting a couple of these last season, and have since replaced most of my steel screws with these. I've used other brands aluminum screws, and BD have the best feel. The wire gate extension feels more durable and solid that other "express handles" and the extra leverage makes them easy to place quickly. definitely an improvement from the steel screw express handle. A few reviews have talked about them getting stuck. This seems to be an issue with aluminum generally rather than these specifically, and I have had the same issues with competitors screws. I do find that in really wet ice they will freeze in place more readily than steel screws, and feel almost like they bottomed out. with a good twist to break the resistance they will usually drive the rest f the way as normal. The longer screws provide meaningful weight savings. For V-threads the larger bore is somewhat helpful, and the green anodization makes seeing the screw path in the ice easier than steel screws. Finally, since these have a larger diameter than almost anything else on the market (petzl UL is slightly larger), the ability to rebore holes is nice, especially in areas that get Swiss-cheesed every weekend. as more people use UL screws this advantage will diminish.

Rated 5 out of 5 by from What a game changer I am a person who carrys a lot of ice screws. I find that 12-14 screws in a 70 meter pitch is adequate. Harder pitches I bring a few more screws. The new ultralight screws have been a game changers for me. My rack is much lighter and way less cumbersome. I could not be more psyched on the lightweight screws!
