This closed-end hex nut with a single external thread is machined from H59 brass and supplied with a cleaning and passivation treatment. It functions as a threaded spacer, blind-hole support nut, or standoff for chassis and enclosure assemblies. The hexagonal body allows tightening with a standard wrench, while the closed internal thread prevents screws from passing through the body. It has a hex outer diameter of 7 mm, a total length of 10.8 mm, and an internal M5 metric thread. The blind-hole design suits applications requiring spacing, elevation, or support between panels in electronic and mechanical assemblies.

FAQ and Solutions
Q1: What is the function of the closed internal thread?
A: The closed thread and blind hole prevent a screw from passing through the body. This suits spacing and support functions where a defined thread depth is required and through-access is not needed.
Q2: How is this part installed?
A: The external thread is fixed into a threaded panel or chassis, and the hex body can be tightened with a wrench. A mating screw is then threaded into the internal M5 thread.
Q3: What is the purpose of the cleaning and passivation treatment?
A: Cleaning removes machining oils, chips, and surface contamination. Passivation supports corrosion resistance on the brass surface. Together they prepare the part for use in electronic and mechanical assemblies.
Q4: What information is needed for a custom quote?
A: Please provide hex outer diameter, total length, internal and external thread sizes, blind-hole depth, material, surface treatment, quantity, and any drawing or tolerance requirements.
