1646 Description

Short technical summary and product information.

The Keystone 1646 is a male-female hex standoff designed for spacing and mounting printed circuit boards. It is made from brass with a nickel plating for corrosion resistance and durability. The standoff has a #6-32 thread size and is threaded throughout its entire length.

With an overall length of 57.15 mm (2.250 inches) and a between board height of 50.80 mm (2.000 inches), it provides precise separation for PCB assemblies. The hex shape measures 6.35 mm (0.250 inches) across flats, allowing easy installation with standard tools.

This component is commonly used in electronic enclosures, test equipment, and industrial control systems where reliable mechanical support and electrical isolation between boards is required. The nickel plated brass material ensures good conductivity and resistance to environmental factors.
