Product Description
Nuts are fastening components that screw together with bolts or screws to secure parts in machinery and equipment. Available in various materials including carbon steel, stainless steel, and non-ferrous metals like copper.
The nut connects mechanical equipment through internal threads, matching with bolts of identical specifications. For example, an M4-P0.7 nut connects only with M4-P0.7 bolts (where M4 indicates ~4mm inner diameter and 0.7mm thread pitch). Similarly, 1/4-20 nuts pair exclusively with 1/4-20 screws.
