Leading-edge technology and precision manufacturing have defined Keystone’s performance as a world-class manufacturer of precision electronic interconnect components and hardware since 1950.

We manufacture precision stampings, in metallic or nonmetallic materials for all industries, and are specialists in progressive dies, four slides, wire forming, in-die tapping, and high-speed blanking. Screw machine products are made with automatic machinery and support equipment to produce precision turnings from .020” to 1.00” diameters. Our assembly procedures include eyeleting, riveting, staking, swaging, inserting, crimping, and screw insertion, with automatic
and semi-automatic operations assembling components into finished products.

Our Product Design Guide M70 features products that are engineered specifically for use by OEM Designers and Engineers who create and develop state-of-the-art electronic
products, instruments, and systems.
While our catalog products meet most standard requirements, modifications as well as custom fabrications can be manufactured to meet customer-specific needs.
