There are two types of acorn nuts. One is low, or the standard acorn nut. The other is the high acorn nut. The high acorn nut is wider and higher and will protect extra long studs. There are also self-locking acorn nuts that have distorted threads in the hex area to create a tight friction fit to prevent the nut from vibrating loose. We provide Acorn Nuts that are made from top-class metal, having a quality for which there is no alternative available in the market with a variety of dimensions ranging from M3 to M100 and quantities from 1 to 90,000. Find a wide selection of Acorn Nuts at the Mahabali Steel Centre.
