Self-Drilling Screws for Iron Plates Power Point Type: Countersunk Head Size: 4.0 x 25mm Quantity: 100 pieces Material: Steel/Unichrome Applicable Plate Thickness: Up to 3.2mm These will be shipped in bags of 100. Other sizes are also available, so please comment if you're interested, and I'll prepare them depending on stock. Shipping will likely be via Yu-Packet, so I can combine items up to 1kg and offer a discount for set purchases. These are surplus items, so while I believe there are no issues with the product, I cannot offer a complete guarantee. The screws themselves are, of course, unused. What are self-drilling screws? They have a drill-bit shaped tip, making it convenient to install them into iron plates without pre-drilling. You can drill, insert, and tighten with a single screw. They are also often used as a substitute for wood screws. I also have various other types of screws for sale, so please take a look at my home page if you'd like (^-^) There are also great value sets! I have many other screws for sale, so please take a look! ↓↓↓ #KontaDIY DIY Screws Bis (Screw) DIY Drill Power Point Pan Head Countersunk Head Shin Washer Iron Self-Drilling Screws Hobby For Iron Plates #DIY #Screws #Bis #DIY #Drill #PowerPoint #PanHead #CountersunkHead #ShinWasher #Iron #SelfDrillingScrews #Hobby #ForIronPlates #Carpenter
