Table of Contents
Knurled nuts, also known as round nuts, grip nuts, quick-tightening nuts, and decorative nuts, feature cylindrical shapes with textured sides to facilitate hand-tightening. The texture, or knurling, is created through rolling or cutting processes, producing fine bumps and dents for improved grip.
Used similarly to regular nuts, knurled nuts fasten machinery and equipment together with bolts. Their unique feature allows for tool-free tightening, making them ideal for environments where tools are impractical or prohibited, such as clean rooms in pharmaceutical, food, and semiconductor manufacturing.
Knurled nuts come in flat and twill knurling patterns to ensure a non-slip grip, allowing for sufficient tightening by hand.
Knurled nuts vary by shape, dimensions, screw holes, knurling type, and material. Shapes include standard cylindrical, stepped, and flanged. They can have non-through or through screw holes, and knurling patterns like flat and Ayame (twill) for different grip effects. Common materials include stainless steel, brass, and resin + brass.
Selection should consider the nut's size, material, and knurling type. Twill knurling is recommended for stronger tightening. Consider the ease of grip, the required tightening strength, and the installation space when choosing the appropriate knurled nut.
