Nuts
Black Diamond Micro Stopper Set 1-6
Black Diamond Micro Stoppers
Great! They don't tend to pull through the rock as the brass ones do.
Black Diamond MiniWire Carabiner
Incredible value, buy individually, or as a pack. Colours match BD, DMM, WC cams, hexes etc.
Black Diamond Offset Micro Stopper Set 1-6
Probably the best small nut out there. Comes with free carabiner. Over the years I have taken a number of falls on the smaller sizes, although it's not recommended. Any nut is better than no nut!
Black Diamond Offset Micro Stoppers
Makes a great companion to the ordinary micro stoppers. Don't know why offsets aren't more popular, I use mine all the time.
Black Diamond Offset Stopper Set 7-11
Should be a useful nut, quite different from the DMM offset. If you're after two sets of offsets I'd suggest one of each.
Black Diamond Stopper Pro Set 1-13
Black Diamond Stopper Set 4-13
Black Diamond Stopper Set 5-11
Black Diamond Wired Hexentric Set 4-10
Same colour run as cams and about the same sizes. Set comes with a free carabiner.
Climbing Technology Carved Chocks Set 1 - 11
Highly recommended by UK Climbing. Slightly different sizing to other brands, so make a good second set. Great price.
DMM Alloy Offsets
The best and most useful nuts ever made, I've never used anything better. Available individually or as a set.
DMM Brass Offsets
DMM Brass Offsets Set 7 Sizes
DMM Half Nut Set 1-7
DMM Perfect O Straight Gate Carabiner
Buy individually, or buy the multi-pack. The best racking biner I've seen.
DMM Torque Nuts Set 4 Sizes
DMM Torque Nuts Wired Set 4 Sizes
Primarily designed for winter climbing, however, I can see many advantages for use on summer rock.
