8mm (5/16") Black Hole Plugs are plastic hole plugs to cover, conceal and decorate 8mm or 5/16" inch diameter holes in cabinets, furniture, window frames, vinyl fences and elsewhere. 8 mm (5/16") diameter holes. Hole Cover Widgets work practically anywhere indoors and out. Made from high-impact injection molded plastic. More colors.
I collect miniatures and these work great to securely seal items in small glass bottles. Great product.

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.

5/16" ~8mm Black Hole Plugs
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.

Look Great, but Loose Fit
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.

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

5/16" black hole plugs.
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.
Jerry T, Villa Rica, GA - 8/24/2015
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.
Mark E., Central New York - 1/19/2015
The Best. Will buy again.

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.
Dwayne M., Illinois - 2/21/2014
Exactly what I was looking for
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!
Dennis W., New Jersey - 2/17/2014
Exactly what I needed for my FJ Cruiser
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.
James S., Virginia - 7/18/2013
Quick shipping and great product. Can't ask for anything more.

Toyota FJ Cruiser Bling Ring Screw Covers
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.
War Wagon, Blowing Rock, NC - 6/15/2013
Works great and fast service, would purchase again.
