These M-F (male-female) aluminum standoffs are great for separating stacked components or chassis tiers. Each hexagonal standoff is 3/16” wide with male threading extending 3/16” to 1/4” from one end (dimension M on the mechanical drawing to the right) and female threading to a depth of 3/16” to 1/4” in the other end (dimension F). A variety of lengths are available with either 2-56 or 4-40 threading.
The standoffs can be screwed together to make longer standoffs.
F-F (female-female) standoffs with threading running through the entire length of the body are also available.
We carry a variety of 2-56 and 4-40 screws and hex nuts that can be used with these standoffs.
