Dorman 370-225 Trailer Floor Screws - Torx 1/4-20 In. x 2-1/2 In. - Black Universal Fit

Pre drilled with 7/32nd and drove these right through 1/8 in mild steel. Everything worked perfectly. I had zero failure, every single bolt threaded snug. The job took less than half of the time I expected because these work so well.

Good product used when we placed the 2x8 deck boards on our 14’ utility trailer. Use in conjunction with drill bits to pre-drill the frame. We had zero problems with these fasteners.

Worked just as described…would buy again

Worked great all around only had 2 not work

Standard deck scree but not forgiving. This might be the standard, however if you dont' have the correct size bit, it doesn't work. No self drilling tip on these

Predrilled, worked great.

Dorman always seems to make better replacement fasteners. Needed to replace the deck on my trailer. These are great for that purpose

These worked perfectly attaching 2x8 pressure treated boards to my heavy duty trailer frame. Drilled the hole with the 7/32 bit through both the wood and the metal, switched to the T30 bit and screwed it down. I put in 36 screws in less than an hour. There was no need to drill out the wood with a larger bit like I expected I would have to do. If you have 2 drills, even easier. Easy as pie. Very pleased with the product. Not one stripped or broke a head off. Would definitely purchase again.

Used about 300 screws and didn’t strip one. 22x8 trailer deck, would highly recommend

Couldn’t find where I live. Used to redeck pull trailer. 0 slips or failures over 150 screws into metal. Taper head leaves smooth finish unlike hex head equivalent.

Durable and easy to use. This was exactly what we needed for the job!

Great product

Was very happy with them, i used nearly 100 of them
