Hex Thin Nut DIN439 DIN936 is low-profile hexagonal nuts that fall between the height of a standard full nut (DIN 934) and the more well-known DIN 439 half nut. Also called thin nuts or jam nuts, they are often used alongside other nuts in locking arrangements. Their slim, flat profile makes them useful in tight spaces or where only a few threads of a bolt need engagement.
