Stainless Steel Cone Point Grub Screw - Grade 202, 304, 316, A2, A2-70

A type of headless screw, the cone point grub screw (also referred to as a cone point set screw), is specifically designed to create a firm, semi-permanent hold by applying compressive force. Its distinctive characteristic is its pointed tip, which concentrates pressure upon tightening and enables it to effectively grip the mating component. Such screws are often utilized in securing rotating parts (such as collars, gears, and pulleys) onto shafts.

A Cone Point Grub Screw (also called a set screw) is a type of headless fastener used primarily to secure an object within or against another object, typically without protruding above the surface.

Drive Type

Hex Socket (Allen)

Hardness

45–53 HRC

Typical Sizes (Metric)

M3 to M20

Tensile Strength

~700 MPa

Cone Point

The pointed end is specifically crafted for thorough insertion and strong grip, particularly when fastening parts onto rods or similar circular items.

Headless Design

Grub screws are ideal for situations where a visible head would be less than desirable, as they are specifically designed to be driven flush with or below the surface.

Internal Drive

These sockets usually have an internal hex drive, although there are also options for slotted and other drive types.

Materials

A range of materials are offered, such as stainless steel, carbon steel, and other alloys, to accommodate various environments and uses.

Holding Power

The cone point is known for its superior holding power compared to other point types, thanks to the intense pressure it applies.

Semi-Permanent Fastening

Cone point grub screws are ideal for applications where a secure hold is necessary, yet periodic removal may be required for maintenance or fine-tuning purposes.
