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.
