- Who it's for
- Trad climbers who want small cams (sizes 0–0.75) that fit shallow, narrow, or horizontal placements where a standard C4 won't go. Hosts consistently recommend them as a second set on a double rack in finger-sized pieces, sizes 0.3–0.75.
- What people are saying
- Hosts overwhelmingly favor these as their top small cam, citing the narrow head width and flexible stem as the defining advantages. No notable criticism appears across the notes; praise is one-sided and consistent.
- Worth noting
- Only available in sizes 0–0.75, so C4s are still needed for larger sizes. One host flags trigger wire durability as something to be mindful of, advising against frequent falls on small gear.
Cal Seeley's review
The Z4 cams are some of the most versatile cams around. Their narrow head width and large camming range lets them fit in places where a standard C4 or equivalent just won't. I carry a single rack of these from .1 - .75.

Cora Hanson, AMGA Single Pitch Instructor
With a super flexible stem that prevents walking and a narrow head width that fits in tight placements, these cams fit where many others won't. I normally carry singles in the Z4 including 0.3, 0.4, 0.5, and 0.75.

A nice refinement over the the C4 cams, the Z4's have smaller heads which allow them to fit in more placements. Love them.

In my opinion, nobody makes better spring-loaded camming devices than Black Diamond. So, if you want to get into building trad anchors, go for some Black Diamond Z4 cams. They’re strong, durable, and reliable.

my favorite cam in smaller ranges. has a flexible stem to inspire more confidence when direction of pull of the placements is a concern. (I use the z4 cam from .1-.75)

Excellent cam head widths. Perfect for shallower cracks and horizontal placements. Hard to go to anything else in these sizes once you've converted!

The Z4's are my favorite cams on the market. Since they are only available for the small sizes (0 to 0.75), I would recommend buying Z4's in all the sizes available, then get C4's for the larger sized cams. For full-rack quantities, you'll want two of each for size 0.3 to size 3. Only one cam needed for sizes 0, 0.1, 0.2, and 4.

These are my cams of choice for small cams. I have a full double rack of these and I really love the sizing & color matches for my brain to know what cam I have. The smaller heads and flexible stem are a huge pro.

Z4s are a great small cam. Their narrow head and flexible stem allow them to be placed in small pods, and tight spaces. In my "standard rack" I carry two each in 0.3-0.75, occasionally supplementing with the smaller sizes

The Z4 Cams are incredible BD Cams that follow the same sizing as the traditional C4's, but have a more narrow head. The smaller head of the cam allows you to place cams in certain cracks/pin scars that a C4 can't fit. Z4's serve as an incredible second half of your "double rack" in your finger sized pieces.

If you have the $$ then pick these up in the smaller sizes instead of the Camalot C4s. These go into places that the C4s wont fit, and feel just as bomber.

Can’t go wrong with a rack of these

My preferred small cam due to the flexible stem and consistent sizing. I haven't had any issues with trigger wire durability but do my best to not fall on small gear.

Brent Smith, AMGA Rock Guide and Apprentice Alpine Guide
The Z4's are my favorite small cams; they have a flexible stem to allow for horizontal placements, and a more rigid flex when placing and removing them in cracks. The narrow head width means they fit almost anywhere!
Recommended in Trad Climbing
I think these are the best small cams. I use these for sizes 0.75 and smaller.
Recommended in Rock Climbing
The narrow heads on these cams allow them to fit into tricky placements. They are flexible when you want them to be and rigid when you need them to stay in place.
