Wensilon（300pcs）#8×3/4” for Sheet Metal Self-Tapping Screws 410 Stainless Steel Truss Head High-Strength Quick Tapping Screws

Description

Wensilon #8×3/4” sheet metal screws are made from premium 410 stainless steel, giving them exceptional strength and corrosion resistance. The hardened 410 alloy (11.5–13.5% chromium) provides high hardness and wear resistance. These self-tapping screws are magnetic, so they cling to magnetic tools for easy installation.

The truss head design gives each screw a wide, low-profile head for a larger bearing area. This helps prevent the screws from pulling through thin sheet metal or soft substrates. The Phillips drive recess is compatible with standard bits, making installation quick and efficient. Each precision-threaded screw forms its own mating threads as it is driven in, so you can fasten into sheet metal, plastic, or similar materials without pre-tapping.

Use this 300-piece kit for metal roofing, HVAC ductwork, automotive panels, appliances, and more. Wensilon is a professional fastener brand known for quality manufacturing. The stainless steel construction and wide truss heads ensure a long-lasting, reliable hold in your projects.

Benefits of Using This Product

• Corrosion Resistance: Stainless steel construction resists rust and corrosion, making these screws ideal for indoor or outdoor use.
• Self-Drilling Design: The sharp self-drilling point (#3) cuts into metal (up to 12 gauge), eliminating the need for pilot holes.
• Large Bearing Surface: The wide truss head provides greater contact area, reducing pull-through in thin metal or soft materials.
• Magnetic for Ease: The 410 stainless steel is magnetic, so screws stick to magnetic bit holders and stay in place during driving.
• Versatile Applications: Perfect for metal-to-metal fastening in roofing, automotive, HVAC, electrical enclosures, and general metalwork.

FAQs

Q: What are sheet metal screws used for?
A: Sheet metal screws fasten metal parts or metal to other materials without the need for nuts. They create their own threads as they drive, making them ideal for roofing, automotive panels, HVAC ducts, electrical boxes, appliances, and more.

Q: Can I use these screws on wood or plastic?
A: Yes. These #8 screws will also hold in wood or plastic. The wide truss head prevents pull-through in softer materials. For very thick wood, use a wood screw instead.

Q: Do I need to pre-drill holes?
A: Not usually. The sharp Type-AB point drills and taps up to 12-gauge sheet metal in one go. For very hard or thick metal, a small pilot hole can help.

Q: Will these stainless steel screws rust?
A: Grade 410 stainless steel is corrosion-resistant, so these screws resist rust under normal conditions. They are fine for outdoor and indoor use.

Q: Are these screws magnetic?
A: Yes. 410 stainless is magnetic, so the screws stick to magnetic drivers or nutsetters, which simplifies handling.
