Separate or connect parts with these unthreaded spacers.
Lightweight, corrosion-resistant nylon is commonly used in electronics applications because it is nonmagnetic and nonconductive. It may absorb moisture, causing dimensional changes.
At roughly 1/3 the weight of steel, aluminum is a strong, corrosion-resistant metal commonly used for its lightweight properties. Material is nonmagnetic.
This magnetic material is the most common choice for everyday fastening applications. Chrome plating provides a mildly corrosion-resistant, attractive finish.
Recognizable by its bright yellow color, brass is a relatively soft, corrosion-resistant material that is nonmagnetic.
All have a hex shape for tightening with a wrench.
A retaining rib grips the threads and holds the spacer in place on the screw.
