Frequently Asked Questions (FAQ)
Q1: What is the difference between an M6x16 hex bolt and a hex cap screw?
A: In many international standards (like ISO), the terms are often used interchangeably for fully threaded fasteners. However, in some contexts, a "bolt" is designed to be used with a nut, while a "screw" is designed to mate with a pre-formed internal thread. Our M6x16 hex bolt is fully threaded and can function effectively in both scenarios.
Q2: Can you provide M6x16 bolts in stainless steel for marine environments?
A: Absolutely. For highly corrosive environments like marine applications, we recommend our A4-80 (316 stainless steel) grade M6x16 hex bolt. It offers excellent resistance to saltwater and chlorides. Hot-dip galvanized steel is another robust option for outdoor exposure.
Q3: What is the recommended torque for tightening an 8.8 grade M6x16 hex bolt?
A: Torque values depend on the friction condition (lubricated or dry). As a general guideline for a zinc-plated, dry 8.8 grade M6 bolt, a torque of approximately 10 Nm is typical. We strongly advise consulting engineering guidelines for your specific joint design and safety requirements.
Q4: Do you offer smaller packaging for samples or low-volume orders?
A: Yes. We understand the need for prototyping and testing. We can supply sample quantities of our M6x16 hex head bolts in small, labeled packages. For production runs, we offer bulk boxes, cartons, or custom palletized packaging.
Q5: How do I place a custom order for a non-standard length or finish?
A: Custom orders are a core part of our service. Simply contact our sales team with your detailed specifications (e.g., material grade, exact length, specific finish like black oxide). We will provide a quotation, lead time, and support you through the process.
