The main materials for medical screws range from titanium alloy and stainless steel to biodegradable materials. Titanium alloy is widely used due to its excellent biocompatibility, lightweight, and strength, but it’s relatively costly.Stainless steel offers good mechanical performance and cost-effectiveness, although its biocompatibility isn’t as good as titanium alloy.Biodegradable materials slowly decompose in the body, removing the necessity for follow-up surgery to extract the medical screws. But their mechanical properties may not be as good as metal screws.
Medical screws ensure stability and safety inside the body through precise design and manufacturing processes. Including optimized thread design and surface treatment to enhance their grip in bone and promote bone integration.Moreover, using high-quality materials and strict production standards ensure the biocompatibility and corrosion resistance of the screws. Reducing the risk of in-body reactions and complications.
Self-tapping screws have special threads that can directly cut into bone without the need for pre-drilling. However, self-drilling screws come equipped with drilling features at their tips, allowing them to penetrate bone without necessitating pre-drilling. Both aim to reduce surgery time and minimize damage to bone.


When choosing medical screws, factors such as the type of surgery, location, and size of fracture or defect. And the patient’s bone quality needs to be considered. Typically, doctors refer to our guidelines and specifications. Based on surgical requirements and experience select the most suitable screw size and type.
When evaluating suppliers, consider factors such as ISO 13485, production and testing standards, past customer feedback, and case studies. Additionally, good ASS, technical support, and flexible customization capabilities are also important considerations.
The biocompatibility of medical screws is verified via a sequence of clinical studies and lab tests. Includes cytotoxicity tests, allergy reaction tests, and chronic toxicity tests, among others. The tests guarantee screw materials are safe for use in the human body.
Medical screws need to be stored in a dry, clean environment. Undergo appropriate sterilization following our guidelines to maintain their sterility until use. Different sterilization methods may be suitable for different materials and products.
