Frequently Asked Questions
Q1: What is the difference between a set screw and a grub screw?
A: They are essentially the same. "Grub screw" is a common term for a headless set screw that is fully threaded and designed to be driven by an internal socket.
Q2: Which point type should I choose for my application?
A: Cup points are the most popular for general use. Cone points are best for permanent settings, while dog points are ideal for preventing rotation on shafts with pre-drilled holes.
Q3: Do you provide samples before bulk orders?
A: Yes, we can provide samples for quality verification. Please contact our sales team to discuss specific requirements.
Q4: What is the highest grade of set screws you offer?
A: We offer high-tensile alloy steel set screws up to Grade 12.9, which provides excellent strength for industrial applications.
Q5: Can you produce non-standard sizes?
A: Yes, we offer OEM/ODM services and can customize dimensions, thread types, and finishes based on your technical drawings.
Q6: What surface treatment is best for outdoor use?
A: For outdoor or high-moisture environments, we recommend Stainless Steel (SS316) or treatments like Dacromet for superior corrosion resistance.
