Acorn nuts are a type of fastener whose name comes from its shape. It is a hex nut with a closed-end, domed top to cover the exposed threaded end. Acorn nuts are easily removed for maintenance to be performed. They also provide an aesthetically pleasing finished look. Acorn Nuts are available in 304/18-8 Stainless Steel, 316 Stainless Steel, Brass, Chrome Plated, and Nickel Plated finish.
High Crown Acorn Nuts are Cap Nuts with an extended domed top to receive a longer threaded portion of a screw, bolt, or other threaded fasteners. This creates a deeper thread depth and higher dome for aesthetic and practical benefits.
Extra Tall Acorn Nuts (also called Extra Tall Acorn Nuts or Extra Tall Cap Nuts) are precisely what they sound like. They are standard cap nuts with a significantly increased height. This added height allows for a greater internal thread depth, which means that more of a bolt or machine screw can be inserted into the nut. Many Applications use this feature for both practical and finish reasons to keep the bolt or screw thread within the cap nut.
