Micro Wallnuts


Small but mighty.

The large contact surface area of the Micro Wallnuts allows them to spread loads over a greater area of rock, decreasing the chance of the rock failing.

They feature straight sides to give alternative placement options to our other alloy micro-protection. Used in conjunction with Peenuts they provide comprehensive protection for small cracks in friable rock.


Micro protection for small cracks

As climbs become harder, the need to make the most of all available protection increases. Micro protection lets you protect cracks which normal sized pieces would not fit. Having these wires on your rack gives you more options.

Large surface area effectively dissipates force

These nuts have large surface areas that spread forces in a fall across a greater area, increasing placement security in fragile rock. They increase security on routes where fragile rock may be encountered.

Colour coded for easy size identification

The DMM protection range is colour coded on the anodised nut and shrink wrap for quick and easy size selection.

Passive protection works in wet and icy conditions

Passive protection works by jamming in constrictions to prevent falls. It is suitable for use in all conditions. Unlike active protection such as cams, passive protection can be used in wet or icy cracks, where friction is reduced.

Piece of mind

Disclaimer, I've never fallen on these. However, having these on my rack give me that little bit of extra piece of mind when I am climbing sketchy, run out climbs, especially with those few sports climbs with some tiny little cracks.

Joe Griffiths
Small nuts, big climbs

So useful for big climbs. Not sure i'd want to take a fall on the smallest ones, given their rating, but definitely better than nothing!

Simon Perrett
Good for fine cracks

Great when you’ve got fine cracks to protect. Usually try and place a couple together for peace of mind

Better and more useful than you'd think

I got recommended these by a mate, and haven't looked back. They are the same side size as some of the 'RPs' but they have a much larger face size. So they fill the crack out really well, and stay in much better. Great for pin scar cracks
