Buying Guide
Key considerations for choosing No. 12 self tapping screws:
- Material and corrosion resistance: Choose 410 stainless steel for outdoor or high-humidity environments, or a coated finish when aesthetics matter.
- Head type and drive: Hex washer heads offer strong bearing surfaces; Phillips or pan heads suit different countersinking needs and tool availability.
- Length and thread: Ensure the length penetrates the material without protruding excessively; deeper threads improve holding power in metal.
- Magnetic vs non-magnetic: Some stainless steels are magnetic and can affect certain projects; verify substrate compatibility.
- Kit composition: For mixed projects, select kits with a range of sizes; avoid over-buying one size for use-cases that require variety.
- Application notes: Self drilling capability saves pilot holes but verify material thickness to avoid stripping or breakage.
FAQ
- What is No. 12 in self tapping screws? Answer: It refers to the screw diameter, approximately 5.5 mm, commonly used for metal-to-metal or metal-to-wood fastening in thin sheets and hardware installations.
- Are No. 12 self tapping screws suitable for aluminum? Answer: They are generally not ideal for aluminum; verify material compatibility before use.
- Do I need pre-drilling for No. 12 self tapping screws? Answer: Most self drilling screws are designed to drill their own pilot holes in thinner metals, saving time.
- What is a hex washer head? Answer: A hex washer head provides a larger bearing surface for better load distribution and reduced cam-out.
- Which rust resistance is best for outdoor use? Answer: 410 stainless steel offers good corrosion resistance, but consider additional coatings for severe exposure conditions.
- Can I use these screws for wood? Answer: Yes, self tapping screws can fasten wood and metal together, though performance depends on material thickness and screw length.
