Star Socket Shoulder Screw
Star socket head (Torx Socket compatible) shoulder screws provide a cylindrical head with a recessed six-pointed, star-shaped socket drive and an integral shoulder between the head and thread. The head is the largest diameter of the recessed star socket shoulder screws, followed by the shoulder and thread. Only the thread of a star socket screw is embedded, allowing the shoulder to extend beyond the part surface and create a journal.
Ondrive’s star screw socket’s unique design allows for rotational or axial motion of the component mounted on the screw, making these screws an excellent choice for mounting bearings, bushings, gears, pulleys, sprockets, and other rotating parts.

Torx Socket Head Screws for High Torque Exertion
The shape of a star screw drive allows for high torque exertion and prevents “cam out” that can damage or break the screw head and tooltip. The ability to achieve higher torque also means a smaller fastener's head can be used in applications where space is limited.Star Socket Screws for High Torque Tightening Applications
Star socket head screws are highly versatile and used by industries ranging from aerospace to consumer goods. In addition to mounting rotating parts, they can be used as linear slides for aligning die and mold halves in punch-and-die or injection molding applications.Star Screw Socket Material Options
Star socket screws from Ondrives.US are Torx® compatible and available in 303 stainless steel. This austenitic material is cold-drawn and widely used to manufacture precision fasteners. It provides Rockwell B83 hardness, good corrosion resistance, and enhanced tensile strength.Torx Socket Shoulder Screw Tolerance Measurements
Our recessed star screws are precision grade and have a tighter shoulder diameter and shoulder-length tolerance than commercial shoulder screws. We offer a broad range of standard, in-stock sizes to give you more flexibility in finding the right star head socket screw for your precision application. We also provide custom sizes and materials upon request.Measurements are as follows:
- Head Height: measured from the top to bottom of the screw head
- Shoulder Length: measured from under the screw head to the bottom of the shoulder
- Thread Length: measured from under the shoulder to the tip of the thread
Selecting the Right Recessed Star Head Shoulder Screw Size
Shoulder length and diameter are the portions that create the journal; thus, they are essential factors in selecting a Torx® compatible head screw. The shoulder must be the appropriate size for secure mounting and proper rotation or alignment. Our Shoulder Screw Buyers Guide provides additional information about selecting the right hexalobular star socket screw for various rotational and sliding applications.View our product specifications PDF to see a complete listing of our in-stock recessed star screw sizes. All sizes are listed in inches and specified by head diameter and height, shoulder length and diameter, thread length and type, and star drive size. Custom sizes are also available upon request.
