FAQS on bolt hex flange head
Q: What are hex flange head bolts used for?
A: Hex flange head bolts integrate a washer-like flange to distribute load evenly, eliminating separate washers. They provide vibration resistance in machinery, automotive, and structural applications.
Q: Are stainless steel flange head self-tapping screws corrosion-resistant?
A: Yes, stainless steel flange head self-tapping screws offer excellent corrosion resistance due to their material composition. They're ideal for outdoor, marine, or chemical-exposed environments requiring durable fastening without pre-drilled holes.
Q: How do flange head bolts differ from standard hex bolts?
A: Flange head bolts feature an integrated radial flange beneath the hexagonal head, acting as a built-in washer. This design increases bearing surface area for better clamping force and stability compared to standard hex bolts needing separate washers.
Q: Can stainless steel flange head bolts handle high temperatures?
A: Yes, grade 304 or 316 stainless steel flange head bolts withstand temperatures up to 1500°F (816°C). They maintain integrity in high-heat scenarios like exhaust systems or industrial equipment.
Q: What materials are flange head self-tapping screws available in?
A: Common options include 18-8 stainless steel for corrosion resistance and carbon steel with zinc plating. Specialty coatings like galvanization enhance durability for specific environments like construction or automotive assemblies.
