These 1/4"-20 square nuts are essential fastening components designed for reliable mechanical connections. Made to Grade 2 specifications, these zinc-plated nuts offer good general-purpose performance for standard applications. The square shape provides excellent grip for wrenches and prevents rolling, making them ideal for assembly work. The zinc plating helps protect against corrosion and extends the life of the fastener. The 1/4"-20 thread size is a common standard, with 1/4 inch diameter and 20 threads per inch, making these nuts compatible with matching threaded bolts and screws. Perfect for construction, maintenance, repair operations, and various mechanical assemblies. The square design also allows for easy installation in pre-cut square holes or channels where round nuts might spin. These nuts maintain consistent performance across typical residential and light commercial applications where moderate strength requirements are needed.
