Frequently Asked Questions (FAQ)
Q1: What is the difference between Grade 5 and Grade 8 for a 2 inch hex bolt?
A: Grade 5 bolts are medium-strength fasteners suitable for most general applications. Grade 8 bolts are high-strength, with a higher minimum tensile strength (150 ksi vs. 120 ksi for Grade 5), making them ideal for critical, high-stress applications like automotive and heavy machinery.
Q2: Can I get these bolts in stainless steel?
A: Absolutely. We offer 2 inch hex bolts in Austenitic stainless steels (304 and 316). Type 304 provides good corrosion resistance, while Type 316 offers superior resistance to chlorides and acids, making it ideal for marine and chemical environments.
Q3: What is the lead time for a custom order (e.g., special coating or material)?
A: Standard items are typically ready for shipment from stock. For custom orders involving special materials, finishes, or large quantities, lead times generally range from 4 to 6 weeks, depending on the specific requirements. We provide a firm timeline upon order confirmation.
Q4: Do you provide certificates for your bolts?
A: Yes. We can provide Mill Test Certificates (MTCs) or Certificates of Conformance (COCs) for our products, detailing chemical composition and mechanical properties, upon request. This is standard practice for many of our B2B clients in regulated industries.
Q5: What is your minimum order quantity (MOQ)?
A: Our MOQ is flexible to accommodate both large projects and trial orders. For standard 2 inch hex bolts, we can often accommodate MOQs as low as one carton or pallet. Please contact our sales team for specific MOQ details based on your specifications.
