5/16" | 8mm Black Hole Plugs

I collect miniatures and these work great to securely seal items in small glass bottles. Great product.

These hole plugs were exactly what I needed. They fit perfectly and were shipped super fast. Thanks!

Product arrived quickly, was perfect for what I needed. Thanks for a great product at a great price and superb service!

Awesome product.

The only source I could find for these. Thank you!

I've been looking all over for a plug that size and no one had them, so really happy you did and they work perfectly.

They fit just right. Thanks.

Used them to plug unused fender holes Fit perfect look great!

Fast service and love the product. We use them for plugging holes after taking static readings.

I ordered these to sample as a possible replacement for a similar item we obtain from a different vendor. These plugs fit the holes in our product better than the other vendors, and the matte surface finish better matched our finish. Lastly, WIDGETCO offers custom color molding for a very reasonable price, which we are now pursuing.

The black 5/16-inch hole plugs arrived quickly, look great and are cleanly molded. I am fitting them into unused 5/16-inch pre-drilled holes in a wooden piece of furniture assembled from a kit made in China (of course). While they fit into the holes and give a finished look, they are loose and some seem to want to fall out easily. I could not go with larger plugs or they would not fit at all. So I wish the fins (thicker parts) on the stem were a little bigger for a tighter fit, which would make them a more flexible choice when holes are not exactly the 5/16-inch size. The photos of the plugs show larger fins on the stem, and look different than the actual plugs I received. I tightened the fit with an old stand-by: a toothpick piece wedged in the hole between the wood and the plugs, and that has worked well. But just 4-star rating since the plugs do not match the photos, and that meant I had to do a bit of extra work to make them fit tightly.

I use these plugs to cover up some Phillip Screw-heads. These plugs are hard to come off which is great news for me.

Quick.

I used the hole plugs to fill the bolt holes after I removed trim rings from my Toyota TRD rims. The plugs fit tight and tapped them in with a rubber mallet. So far so good, they have not moved and they look great, will keep the holes clean. I took the rings off for winter time so that they don't corrode in the salt.

Ordered these to plug holes that someone drilled in dash of farm tractor. Just what I needed at a reasonable price. Second time I ordered from WIDGETCO. I will order again if I need some more.

Great customer service. I ordered a small quantity of the 1/4" plastic hole plugs to fill a 1/4" hole (musical instrument cable connection). Upon receipt, the parts didn't fit (too small). We tried two other orders, each at no additional cost. Unfortunately, none were the exact size, however, the customer service has been outstanding and makes all the difference.

The Best. Will buy again.

Incredibly fast shipping. Excellent product - highly recommended!!

Purchased a slew of Black Hole Plugs of varying sizes...plugs worked great for my project which was covering holes that were drilled into my Harley Davidson Fairing. WIDGETCO was found to be a reliable company with excellent customer service. Highly recommend them!

I have bought 2 types recently and this company has a great website. Received my merchandise within days. This is a five star company to buy from.

Fast shipping and great communication on order status.

It used to be there were real hardware stores, where you could find little gems like this. WidgetCo delivered. My first shipment was lost by USPS. WidgetCo didn't hesitate to send a duplicate order immediately. First Class customer service!

Like what War Wagon said "I needed 60 satin black hole plugs to cover the 8mm holes in the wheels. These worked perfectly, tapping them into place with a rubber mallet. Fast shipping as well." Shipping was faster than I expected. Glad I found this site.

Quick shipping and great product. Can't ask for anything more.

After removing the 'bling rings' on my 2013 Toyota FJ Cruiser wheels, I needed 60 satin black hole plugs to cover the 8mm holes in the wheels. These worked perfectly, tapping them into place with a rubber mallet. Fast shipping as well.

Works great and fast service, would purchase again.

Fast & Superb Service
