We have a cabin. The metal railing was custom made. We thought the installer was going to paint the silver lag bolts black. Intalled silver and it looked terrible. Your covers were a perfect solution to our issue. They worked great and added a professional appearance to our railing. Thank you.

For the price, the difference it makes in a completed product is not to be gone without! Easy to use and once installed doesn't come off without use of a tool which is perfect for its purpose.

I used to buy the 3/8 chrome caps from your company but there’s hardly any chrome on these new vehicles. So I switched to the 3/8 black chrome caps and I love the look on my Chevy truck.

the mortar like substance to add weight to the floor lamp and connect the base dried out and caused separation. Added 1/4" bolts and nuts to hold it together. Caps over the nuts finish it off like it was designed that way!

These black 1/2" caps were just what I needed to make my truck steps complete. Get them lined up and tap them on with a hammer. Done, and they look great. I can't beleive no one in my area carries these and I had to order them. Without the caps a shiny bolt would show. Worst yet that the makers of the steps dont include them with the steps. Shame on you "Bully brand steps".

I repaired my leaky Lund visor on my 1996 Ford Bronco. It was attached with #14 sheet metal screws but the holes in the Bronco roof were damaged and oversized. It took a bit but I found 5/16" sheet metal screws to replace the old ones but the hex size went from 7/16" to 1/2". This caused a dilemma since the old screw caps were to small. After searching the internet I found caps for the 1/2" hex were not a common off the shelf part. After much digging on the internet I found PRO-DEC and there 1/2" hex caps were just what the project needed. Now I am happy on the road with a good looking solution and a leak free roof.

Needed those white caps to put the finishing touches on an aluminum deck railing purchased online. Manufacturer supplied no way to hide ugly screw heads. Thanks to you folks at Pro-Dec

Great product! My bedframe has lots of bolts but didn’t come with covers. And since I’m not using slats, the mattress and bedding were exposed to them - and they scratched my hands when making the bed. These are a huge improvement and shipped/arrived super quickly!

The fabric on my chairs deteriorated over time. Instead of throwing them away i replaced the fabric with wood slates, bolted down with a neoprene nut which I covered with the caps. They worked perfectly.

Add a finishing touch to a seat conversion I did on a hobby truck. I had to fabricated a seat frame and the caps gave a factory look to the way I had to bolt it down. Also really appreciate the courtesy you extended me when I miss ordered. Thank you.

These hex caps fit perfectly over the hex bolt heads that were visible on the base of our new white swimming pool handrail. This gave a much nicer finished look to this part of our recent pool renovation. Arrived in short time after order. Thanks.
