- Who it's for
- Trad climbers who need reliable small cams (sizes 0–0.75) for tight or horizontal placements where standard cams won't fit. Hosts suggest pairing with C4s for larger sizes to build a full rack.
- What people are saying
- Multiple hosts call these their favorite small cams, citing the flexible stem and narrow head width as standout features for tricky placements. The one consistent criticism is that trigger wires wear out within roughly a year of heavy use, though they are non-load-bearing and cheap/easy to replace DIY or via Black Diamond.
- Worth noting
- Available only in sizes 0–0.75, so they cover the small end of a rack only. Trigger wire durability is a known recurring maintenance item, not a safety concern.
Cora Hanson's review
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.

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
Recommended in Trad Climbing
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.

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.

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.
Recommended in Rock Climbing Mentorship Program
These are great cams that come in smaller sizes. I think they are among the best small cams out there. They do have one downside though - The trigger wires aren't particularly durable. The trigger wires on mine usually only last a year, although that's with heavy use. Luckily, the trigger wires are not a load bearing piece of the cam, so there are plenty of easy DIY ways to replace the trigger wires for pennies and about 10 minutes of your time. Alternatively, you can send them to Black Diamond to be repaired,
