Square Nut ZP DIN557

Description

Constructed from Carbon steel, white zinc plated finished, anti-rust and anti-corrosion, coarse thread, superior electrical conductivity. Usually use screws to clamp the connected terminal wire; use a wrench to fix the square nut, and use a drive tool to lock the screw in the tightening position. These square nuts have a 4-sided, square design which provides a greater bearing surface when installing. Square nuts are designed for use with square-headed bolts, though they can also be used with some machine screws. The large surface provides better resistance to loosening. Also used with flat washers of compatible size and material.
