At Fastener SuperStore, our parts selection includes over 650 different spacers of varying materials and sizes, in both hex and round shapes. Spacers are unthreaded and are used to hold components at a set distance apart from one another, usually with a screw or rod holding them in place.

Hex Spacers are available in 6/6 nylon in outer diameters of 3/16", 1/4" and 5/16" diameters (measured across the flats of the hex). Hole sizes of .072, .091, .115 and .140 (equivalent to #1, #2, #4 and #6 screw sizes). Lengths of 1/4" up to 1 1/2" are available.

Round Spacers are more common than hex, as they allow for more clearance room.

Round shaped spacers are also available in 6/6 nylon, as well as in stainless steel, aluminum and brass / nickel. We carry outer diameters of 3/16", 1/4", 5/16", 3/8" and 1/2"; hole sizes from #2 up to #14; and lengths from 1/8" to 1 1/4" can be ordered.
