Aluminum Standoff: 1/2" Length, 4-40 Thread, F-F (4-Pack)
These 1/2"-long hexagonal female-female aluminum standoffs keep parts spaced 0.5 inches (13 mm) apart. They are like elongated, 3/16”-wide hex nuts, with 4-40 threads running through the entire length of each standoff. They are sold in packs of 4.

These F-F (female-female) aluminum standoffs are great for separating stacked components or chassis tiers and can be used as an alternative to our nylon spacers. Each hexagonal standoff is 3/16” wide and has threading running through the entire length, similar to an elongated hex nut. A variety of lengths are available with either 2-56 or 4-40 threading.
Longer standoffs can be made by stacking multiple F-F standoffs on a single screw.
M-F (male-female) standoffs are also available, and can be screwed together or combined with F-F versions to make longer standoffs.
We carry a variety of 2-56 and 4-40 screws and hex nuts that can be used with these standoffs.
