Uncoated plain hex nuts with a natural finish retain the original surface state of the raw material and are supplied without electroplating or chemical treatment. The hexagon profile provides standard wrenching faces for installation and does not carry additional surface coatings that might interfere with downstream processing.

These nuts are intended for applications requiring follow-up surface treatment, such as welding, painting or other secondary processing, and for general equipment assembly and structural connections. Complete specifications are available on request — please confirm required size, thread form, material and mechanical grade before ordering.
