#12 × 3/8" غسالات مسطحة قطر خارجي | سمك .062" | نايلون (1000/عبوة)

I’ve been using these nylon washers under stainless screws on a boat trailer, and they’re holding up great in saltwater conditions without any corrosion or cracking. The 3/8" OD fits perfectly under the fastener heads, and the flat profile distributes the load evenly. A thousand in one package means

The .062" thickness gives these washers a nice firm feel while still being flexible enough to seat flush against the surface. I used them to protect a painted frame under some screws and they did the job perfectly without any cracking.

I needed a bulk pack of nylon washers for a marine project, and these 1,000-count flat washers delivered perfectly. The .062-inch thickness gives them just enough rigidity to hold without cracking under pressure.
