Frequently Asked Questions
Q1: What are set screws (grub screws) used for?
Set screws, also known as grub screws or headless screws, are primarily used to secure an object within or against another object, such as securing a gear, pulley, or collar onto a rotating shaft. They prevent relative movement between the two parts.
Q2: What is the benefit of a headless design?
The headless design allows the screw to be fully threaded and driven entirely into the pilot hole. This creates a flush surface fastening, which is essential for rotating machinery, compact assemblies, and aesthetic furniture components where protruding heads could cause obstruction or safety hazards.
Q3: How do I choose the correct point type (Cup, Flat, Cone, Dog, Oval)?
- Cup Point: The most common type, offering quick and permanent locking.
- Flat Point: Best for frequent adjustments without damaging the shaft.
- Cone Point: Ideal for permanent setting with high holding power.
- Dog Point: Used for aligning parts or locking into pre-drilled grooves.
- Oval Point: Minimizes surface damage and works well with angled surfaces.
- Flat Point: Best for frequent adjustments without damaging the shaft.
- Cone Point: Ideal for permanent setting with high holding power.
- Dog Point: Used for aligning parts or locking into pre-drilled grooves.
- Oval Point: Minimizes surface damage and works well with angled surfaces.
Q4: What materials and grades do you offer?
We manufacture set screws in Carbon Steel (C45, 40Cr), Stainless Steel (SS304, SS316) for excellent corrosion resistance, and high-strength Alloy Steel (Grade 12.9) for heavy-duty industrial applications.
Q5: Do you support customized sizes and OEM packaging?
Yes, Hebei Chudu offers complete OEM/ODM customization services. We can manufacture custom thread profiles, lengths, and drive styles according to DIN, ISO, or ANSI standards, and support custom box designs, logos, and barcode packaging.
