Hex Socket Set Screws

Hex Socket Set Screws, also known as grub screws or hollow screws, are essential fasteners used in various industrial applications to secure objects within or against another object without protruding. These screws feature a headless design with an internal hexagonal drive, allowing for a flush fit that is ideal for applications requiring a smooth surface. Available in a range of materials including steel, stainless steel, titanium, brass, and aluminum, they are designed to suit different environmental conditions and mechanical requirements. The screws come in multiple tip shapes such as flat tip, cone point, cup point, dog point, and more, each providing unique holding characteristics and suited for specific uses. Surface treatments like black oxide, nickel plating, chrome plating, and trivalent chromate enhance their durability and resistance to corrosion. These versatile screws are commonly used in securing pulleys, collars, and gears to shafts, ensuring reliable performance in machinery and equipment.

Material and Construction

Available in a range of durable materials to meet diverse industrial requirements:

Steel: Strong and reliable for general industrial applications.
Stainless Steel: Corrosion-resistant, perfect for humid or outdoor environments.
Titanium: Lightweight, high-strength, and resistant to corrosion for specialized machinery.
Brass: Provides corrosion resistance with an aesthetic appeal, suitable for low-load or decorative applications.

Tip Shapes

Hex socket set screws offer multiple tip options to suit various fastening needs:

Flat End: Provides non-damaging, uniform surface contact.
Cone Point: Ensures precise, centered positioning.
Cup Point: Offers strong holding power for medium-duty applications.
Dog Point: Guides alignment and prevents lateral movement.
Soft Pad/Metal Pad: Protects mating surfaces while maintaining secure grip.
Rounded End: Allows slight adjustments and smooth engagement.

Drive Types

Hex Socket: Standard internal hex drive for tightening with Allen keys.
Cross-Head (Phillips) and Straight-Slot: Optional drives for specific applications.

Surface Treatments

Enhancements such as black oxide, nickel plating, chrome plating, and trivalent chromate improve corrosion resistance, wear durability, and overall lifespan of the screws.

Applications

Commonly used for:

Securing pulleys, collars, and gears to shafts.
Mechanical and industrial components requiring flush fastening without protruding heads.
Ensuring reliable performance in motors, machinery, and precision equipment.
