Cortex Screw 20 TPI

The Cortex Screw 20 TPI from Glass Agencies is an orthopedic fixation implant used for securing plates to dense cortical bone in fracture fixation and reconstructive bone procedures where fine thread engagement is required. This screw features a 20 threads per inch profile, which provides closer thread spacing compared to lower TPI screws, supporting controlled advancement and strong purchase in hard cortical bone. The finer thread pattern helps distribute holding forces more evenly along the bone interface, supporting stable fixation in regions such as the diaphyseal sections of long bones including the femur, tibia, humerus, radius, and ulna. The screw head is contoured to seat accurately within standard dynamic compression plate holes, enabling secure plate-to-bone contact and effective load sharing across the fixation construct. The core diameter and shaft geometry are proportioned to maintain mechanical strength while supporting smooth insertion through predrilled holes. The tip profile assists with predictable entry and controlled cutting action, allowing the surgeon to advance the screw with consistent torque and reduced risk of cortical splitting. Cortex screws with 20 TPI are commonly used in conventional plating systems and are suitable for applications where enhanced thread engagement is preferred, such as in very dense bone or when precise adjustment of compression is needed. The screw is manufactured from medical grade stainless steel or titanium alloy, providing high strength, resistance to corrosion, and compatibility with the physiological environment of the human body. These materials support resistance to cyclic loading and mechanical stresses encountered during the healing phase. The surface finish is carefully controlled to support smooth interaction with bone and surgical instruments, reducing insertion torque and minimizing wear on drivers. The drive recess is compatible with standard orthopedic instrumentation, supporting secure torque transmission during placement and removal. Cortex Screw 20 TPI is available in multiple diameters and lengths, allowing selection based on anatomical location, bone thickness, and plate system requirements. Glass Agencies follows strict quality control processes, including inspection of dimensional accuracy, thread consistency, surface quality, and structural soundness.
