Stainless Steel 304

Composition

304 (A2) is the most extensively used austenitic stainless-steel. It's also known as stainless steel 18/8 which is derived from the nominal composition of 18% chromium and 8% nickel.

Thanks to the chromium content, 304 stainless steel products show excellent corrosion and oxidation resistance.

Weakness

304 Stainless Steel is more likely to corrode from saline environments in coastal areas. That means grade 316 stainless steel is highly recommended for tough applications under the marine environment where there is more powerful acids and chemicals.

Application

  • Hardware (Bolts, Screws, Nuts, Washers and etc.)
  • Sanitaryware
  • Chemical Equipment
  • Machinery
  • Engineering
  • Architectural panelling

These bolts seem built to last. I put them in using an impact driver. They have held up well.

These provide a strong sturdy connection like any other lag bolt with the added bonus of corrosion resistance. The bolts are well formed and seem comparable in quality to others I have used. They don't have any stamp or indication on the head that they are stainless.

I recently received a set of hex lag screws and I am thoroughly impressed with their quality. The 304 stainless steel is sturdy and durable, perfect for outdoor use. The hexagon head design makes for easy tightening with a wrench, and the 3" length provided plenty of depth for securing into wood. I appreciate that they come in a pack of 6, which is perfect for small projects. The packaging was also done well, ensuring that the screws arrived in perfect condition. Overall, I am satisfied with the product and would recommend them to anyone in need of high-quality hex lag screws.

We find this length and diameter lag screw to be very adaptable when building a structure of 2" planks, 1" boards, 3" squares and even 4" squares. The 5/16" size is much stronger than equivalent 1/4" screws, yet not so large as to risk splitting less robust components (we always drill pilot holes, often with a flat washer under the head). Much of our work is with so-called "Ag-Treated" lumber, which can corrode common steel fixtures. We would expect the 304 stainless would be pretty resistant to preservative corrosion ~ The Duffian

Nice solid, well made stainless lag screws - what else can you say. These went in perfectly and seem to be of good quality. My only gripe is they're actually a little bit more expensive per screw for the 15 pack on amazon at about 66 cents each versus 63 cents each when purchased in a 50 pack at that big orange store, but I guess if you only need a handful around for when you need them, to save a trip to the store it ends up being kinda a wash and the convenience of ordering on here makes them worth it.Pretty happy overall.

Lag bolts are one of those items I think everyone should always keep an extra of on-hand!These particular bolts are priced very close to what I would expect to pay from a local big box orange or blue store. The quality is the same and the set I received came with no noticeable flaws such as burrs in the metal or messed up threads.I used 4 of these to mount a Bandsaw to a home-made wooden base and after pre-drilling the holes, these sunk into the wood with ease. I am pleased by the overall quality and this is is a good buy if you don't need them right away for a project.While these are advertised as Stainless steel, I'm not sure I would trust using them in an outdoor application personally.

In my humble opinion, you can never have too many lag bolts. They are good for a wide variety of tasks where a heavier duty attachment is needed. I mostly use these outdoors so the fact that these are stainless steel is a big plus. These are cleanly made without a lot of burrs. They screwed in well during a test. I will be using these to make a cold frame for my garden so I am happy that the stainless steel should last a long time. They also came nicely packaged in a zipper bag and cardboard box.

Not convinced these are 304 stainless steel due to it's attraction to magnets, but none the less they are working very good for my purposes where I'm not going to use them in a dry environment.
