Evelyn ★★★★★

Installed these nylon shoulder washers in a small control panel to keep #4 screws from grounding out—the fit was perfectly centered and snug. They’re strong enough to hold up without cracking, and the pack of 100 should last me through several projects.

Miles ★★★★★

Finally got around to mounting some electronics in a metal enclosure and these shoulder washers made centering the #4 screws a breeze. The natural nylon feels sturdy and the insulation is exactly what I needed for the job.

Riley S. ★★★★★

Used a few of these to isolate a mounting screw from a metal chassis, and the natural nylon held up perfectly against vibration. The #4 size was spot-on for the fastener I was using. Exactly what I needed for the job.
