JEGONFRI (180pcs) #8 x 3/4" 410 Stainless Steel Self Tapping Screws for Metal Plastic & Wood, Phillips Drive Modified Truss Head, High Strength Sheet Metal Screws (#8 × 3/4")

As received (#8 3/4" 410 SS screws) the head diameter measured 0.359 inches. Head diameter should be provided in description. Rough testing indicates that the SS is probably 410 (indoor) SS.

I keep pleanty of these around to replace similar screws. The broad head helps hold.

Good screws for going into plastic. Thanku amazon

Perfect for a small job I have,best price and I didn't have to buy 5x morethan I needed. Thanks.

phillips was great square would be better

These things are brittle! They're sharp and inexpensive but not for any heavy duty jobs.

Tried to run in about four of these screws. The head snaps right off. They are cheaper and better quality at home depot, had to find that out the hard way.

Item description: #8 x 1-inch 410 SST self-tapping screws, 150 ctBrand: JEGONFRIItem: B0C3R2SQF2Date received: 2023-06-07Headline - Good value on self-tapping stainless steel screwsProduct Claims150 ct, #8 x 1 inch self-tapping screwscross-slot drive, modified truss head410 stainless steelno claim of compliance to a standardI received exactly what was claimed in the product description as to quantity (150 count), material (stainless), nominal size (#8 x 1 inch), and type (modified truss-head, cross-slot drive, self-tapping). They arrived loose within a labelled, white and yellow thin pasteboard box imprinted with manufacturers information. The box adhesive label notes a product number X003SZ03CZ followed by "JEGONFRI (150 pcs) #8 x 1" 41... Sheet Metal Screws (8# x 1")". Elsewhere on the box is "Made in China".I did not count the screws individually; I measured the weight of 35 of them (average 1.9823 grams each) and confirmed by weight the total count at 150 screws. The heads are modified-truss head, composed of a washer-like thin annular ring surrounding a deeper mushroom-head dome containing the driver recess.

They appear to be stainless by surface appearance, but 410 stainless (especially highly cold worked material such as this) is about as magnetic as regular carbon steel, so the magnet test that I would normally use for 300-series stainless is not definitive.Why stainless? - stainless screws are not necessarily the highest strength screw you can find (carbon steel screws are normally stronger), but they are normally strong enough for most uses, and they will not corrode (much, some mild surface corrosion is possible). They provide a great broad-based solution for small shops.
