MIDWEST FASTENER CORP 66385 Nylon Snap Bushings 20PK

Snap Bushings for Wire Protection

MIDWEST FASTENER CORP 66385 Nylon Snap Bushings come in a 20-pack designed to protect cables and wires passing through sheet metal or plastic panels. The shallow snap-in design allows quick installation without tools, making them suited for automotive wiring, appliance repair and general electrical maintenance. Each bushing provides a smooth nylon surface that prevents insulation abrasion on sharp panel edges. Builders who need strain relief or threaded inserts should look elsewhere as these are simple pass-through guards.

3/8 Inch ID Fits Standard Cable Bundles

The 3/8 inch inside diameter accommodates common automotive and low-voltage wire bundles while the 1/2 inch mounting hole matches standard panel punch sizes. Twenty pieces give enough spares for multiple panel cut-outs or future repairs. The shallow profile works best on thin panels where deeper bushings would protrude; installers working with thick enclosures or requiring watertight seals will find these unsuitable.

Nylon Plastic Resists Vibration and Heat

Molded nylon construction resists cracking from vibration and handles under-hood temperature cycles better than brittle plastics. The material stays flexible in cold weather and does not conduct electricity, maintaining isolation between wires and grounded panels. Technicians needing metal bushings for grounding continuity or high-temperature ceramic insulators must choose a different product line.
