The Safety Locking Screws – 3.5 mm Stainless Steel 316L – 220 Pcs, Lengths 12–50 mm are specialized orthopedic implant screws designed for use with compatible locking plate systems. This comprehensive 220-piece configuration provides a range of screw lengths from 12 mm to 50 mm, allowing qualified orthopedic surgeons to select an appropriately sized screw according to the patient’s anatomy, fracture characteristics, plate position, and manufacturer’s surgical technique.

The 3.5 mm locking screw is intended to engage with a compatible threaded plate hole, creating a fixed-angle relationship between the screw and plate. This locking interface can contribute to angular stability within an appropriately designed fixation construct. The exact locking mechanism and plate compatibility must always be verified against the manufacturer’s technical documentation.

The availability of 12–50 mm lengths provides flexibility for different anatomical requirements. Correct screw length selection is essential to achieve appropriate fixation while avoiding excessive penetration beyond the intended bone structure. Screw length should always be determined intraoperatively using appropriate measurement techniques and the manufacturer’s recommendations.

These screws are manufactured from 316L stainless steel, a material widely used in medical and orthopedic applications because of its corrosion resistance, mechanical strength, and established use in implantable medical devices. The exact material certification, mechanical properties, and applicable implant standards should be confirmed with the manufacturer.

The term safety locking screw refers to the screw’s intended role within a compatible locking fixation system. It should not be interpreted as a guarantee against surgical or mechanical complications. Proper plate compatibility, screw trajectory, insertion technique, torque control, and patient-specific planning remain essential to achieving the intended fixation outcome.

The 220-piece configuration is particularly useful for orthopedic hospitals, trauma centers, surgical facilities, and medical distributors that require a broad inventory of 3.5 mm locking screws. Multiple lengths in one system can simplify implant preparation and help surgical teams select the appropriate component during fracture fixation procedures.

Only compatible plates, drivers, and instrumentation should be used with these screws. Using a screw with an incompatible locking interface can result in poor engagement, damage to the screw head or plate, or failure of the fixation construct. The manufacturer’s approved combination of components should always be followed.

Before implantation, every screw should be inspected for damage, deformation, corrosion, surface defects, or compromised packaging. Screws that have been previously implanted, used, dropped, damaged, or exposed to contamination should not be implanted unless the manufacturer provides validated instructions permitting otherwise.

Implantable screws are generally intended for single-patient use. They should not be reused or reprocessed for implantation unless explicitly authorized by the manufacturer. Proper storage should protect the screws from contamination and physical damage before use.

The 3.5 mm Safety Locking Screw Set is intended for qualified orthopedic and trauma surgeons trained in internal fixation techniques. Screw selection, length, placement, insertion torque, and final fixation should be determined according to patient anatomy, fracture morphology, bone quality, compatible plate design, and the manufacturer’s instructions for use.

FAQs

1. What are 3.5 mm safety locking screws used for?

They are designed for use with compatible 3.5 mm locking orthopedic plates as part of an internal fracture fixation construct.

2. What material are the screws made from?

The screws are specified as 316L stainless steel.

3. What lengths are available?

The set includes screw lengths ranging from 12 mm to 50 mm.

4. How many screws are included?

The stated configuration contains 220 pieces.

5. Can these screws be used with any 3.5 mm plate?

No. The screws should only be used with compatible locking plates that have the corresponding locking interface and are approved by the manufacturer.

6. Are the screws reusable?

No. Implantable fixation screws are generally intended for single-patient use unless the manufacturer specifically states otherwise.

7. How should the correct screw length be selected?

The surgeon should determine the appropriate screw length based on patient anatomy, bone thickness, plate position, fracture characteristics, and the manufacturer’s surgical technique.

8. What driver is required?

The appropriate driver depends on the screw-head design. Always use the manufacturer-specified compatible driver to prevent damage to the screw or locking interface.
