Finally found some standoffs with proper nylon threads that don't cross-thread on the first twist—these went in smooth and held a small prototype board securely at half-inch height.

Just the right size for lifting a PCB off the panel, and the nylon threads cut cleanly without any burrs. The 1/2" length gave me exactly the clearance I needed for the components underneath.

The threads on these #4-40 nylon standoffs are clean and cut perfectly, so they screw on without any binding. I used them to mount a small circuit board and the 1/2" length gave just the right amount of clearance. Solid little spacers for the price.
