The AO Cortical 2.4 mm Star Head Self-Tapping Screws Set is an orthopedic fixation product designed for use in procedures requiring compatible small-diameter cortical screws. The set is described as containing 112 pieces, including a screwdriver.

Cortical screws are used in selected orthopedic fixation systems to secure compatible implants or support bone fixation, depending on the specific screw design and approved application. The 2.4 mm designation refers to the stated screw diameter; individual lengths, thread specifications, and material details are not provided in the product title.

The star-shaped head design indicates a driver interface intended to engage with a matching screwdriver tip. Correct engagement between the screw head and driver is important for controlled insertion and to help reduce the risk of damaging the drive recess.

Before purchasing, review the full screw inventory and confirm that the screws and screwdriver are compatible with the intended plate system and surgical requirements.

2.4 mm Cortical Screw Design

The product is identified as a 2.4 mm cortical screw set. Cortical screws are generally designed with threads suited to engagement with cortical bone, but the exact thread geometry, pitch, and other technical features depend on the manufacturer and screw model.

Screw length is a key selection consideration because the appropriate length depends on the anatomy, fixation plan, implant design, and clinical requirements. The available lengths and quantity of each size are not specified, so buyers should request a detailed size chart.

The product title also identifies the screws as self-tapping. Self-tapping screws are designed to form threads as they are inserted into an appropriately prepared hole. Whether pre-drilling, a specific drill size, or other preparation is required must be determined from the manufacturer's instructions for the particular system.

Star Head Design and Screwdriver

The star head is intended to work with a compatible driver tip. The exact recess profile is not specified, so the screwdriver interface should be verified before use.

The product title indicates that a screwdriver is included in the 112-piece set. However, it does not establish whether the package contains one screwdriver, multiple drivers, interchangeable tips, or additional accessories.

Using the correct driver helps achieve proper engagement with the screw head. Do not assume that a screwdriver designed for one star-drive profile will fit every screw with a star-shaped recess.

Orthopedic Applications

Small-diameter cortical screws may be used in selected orthopedic fixation applications when their dimensions and design are appropriate for the intended implant and anatomy. The specific clinical applications for this set cannot be confirmed without the manufacturer's documentation.

The treating orthopedic surgeon must determine the appropriate screw type, length, and fixation method. The term “AO” in the product title should not be taken as proof of affiliation, licensing, or compatibility with a particular manufacturer's system unless documented by the supplier.

Material and Product Quality

The screw material and finish are not specified in the product title. Confirm whether the screws are manufactured from stainless steel, titanium, or another material, and obtain the relevant technical documentation.

Buyers should review the manufacturer's quality information, traceability, applicable regulatory status, and instructions for use. These details are especially important for implantable medical devices.

Set Configuration and Inventory

The set is advertised as containing 112 pieces, including a screwdriver. The exact breakdown of screws by length, the number of each size, and the number of accessories should be confirmed before ordering.

A complete inventory list supports purchasing decisions, stock control, and verification that the set meets the intended procedural requirements. Confirm whether the product is supplied in a storage case or organizer, as this is not specified in the title.

Handling, Cleaning, and Sterilization

Follow the manufacturer's instructions for storage, handling, preparation, and sterilization. Confirm whether the screws are supplied sterile or non-sterile and whether the screwdriver is reusable and compatible with the required reprocessing method.

Inspect the packaging, screw heads, threads, and screwdriver tip before use. Do not use damaged components or instruments that fail inspection. Only use the screws and driver according to the manufacturer's instructions and approved clinical applications.

Choosing the Right 2.4 mm Screw Set

When selecting this set, verify the screw diameter, available lengths, thread design, head recess, material, and screwdriver compatibility. Confirm that the components are approved for the intended fixation system and that the 112-piece inventory contains the required sizes and quantities.

A manufacturer's specification sheet and complete packing list are the best sources for confirming product details before procurement.
