Review on 520pcs Metric Hex Socket Pan Head Screws & Nuts Assortment Kit, 304 Stainless Steel M3 M4 M5 Bolt Nuts Flat Washers Machine Screws by Kenny Davey

Product: 520pcs Bolts and Nuts Metric Hexagon Pan Head Bolts Stainless Steel Screws 304 M3 M4 M5 Screw Nuts Washers Mounting Screws Set in Assortment Save time with this assortment of screws , as we homeowners and kids are busy doing weekend repairs . M3 M4 and M5 thread specs are the most common these days so this is a great kit that you probably won't need in a few years. This is 304 stainless steel based on the description as well as the printed description on the box. Normally 304 steel is non-magnetic, but in some cases they become paramagnetic (stick to a magnet), especially in cold working or machining etc. These screws are magnetic as shown in the picture, but that is due to the nature of the thread or the embossing. Process. The quality looks good and in general 304 stainless steel has better strength and corrosion resistance compared to low alloy mild steels. I also find it good value for money.
