What Tools are Needed to Install Open-Ring Metal Snaps? (Click here for text version.)
Open-ring grip snaps are commonly used on baby/children's clothing and other basic crafting projects with thinner types of material (which should be reinforced with twill or grosgrain ribbon to avoid possible tearing). Because the "teeth" are short and each one needs to be able to self-pierce through the fabric, these are not suited for tough, thick or dense material. Size 14 (3/8") has shorter teeth than size 16 (7/16").
