Self-Tapping Locking Screw 3.5mm is a stainless steel veterinary orthopedic implant screw designed for locking plate fixation, TPLO construct support, cortical bone purchase, fracture stabilization, and corrective osteotomy workflows. The available variants are Self-Tapping Locking Screw 3.5mm Length 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, and 70mm. The screw has a 3.5mm diameter, self-tapping pointed tip, locking thread geometry, and hex head drive interface for controlled insertion with compatible veterinary orthopedic instrumentation. It is used during tibial plateau leveling osteotomy, locking plate application, long bone fracture repair, metaphyseal fixation, compression or neutralization plate support, and orthopedic trauma stabilization. Veterinary orthopedic surgeons, referral hospitals, small animal surgical teams, teaching laboratories, distributors, and procurement teams use this screw family where secure plate engagement and accurate length selection are required.
The Self-Tapping Locking Screw 3.5mm uses a pointed self-tapping tip to advance through a prepared pilot hole while forming thread engagement during insertion. The locking head profile is designed to interface with compatible locking plate holes, creating a fixed-angle relationship between screw and plate when the construct is assembled correctly. This differs from standard cortex screws, which rely primarily on plate-to-bone compression through conventional screw seating. The 3.5mm diameter provides a mid-size orthopedic fixation option for veterinary TPLO plates, long bone plates, and selected trauma constructs. The hex head allows controlled driver engagement, torque transfer, axial alignment, and final seating into the plate interface. The shaft threads provide cortical purchase along the prepared track, while the head locks into the plate system according to implant compatibility. Correct placement follows drill guide alignment, depth measurement, compatible driver selection, measured insertion, and final inspection of screw seating.
Clinical use begins after radiographic planning, patient positioning, surgical exposure, osteotomy or fracture reduction, plate selection, drilling, and depth measurement. In TPLO procedures, Self-Tapping Locking Screw 3.5mm is selected when the plate system requires fixed-angle screw engagement around the proximal tibial construct. The screw helps secure the locking plate after tibial plateau leveling, plate positioning, and hole-specific measurement. In fracture repair, it supports locking plate constructs where screw-plate stability is required across cortical bone segments. It may also be used during corrective osteotomy, long bone stabilization, metaphyseal-adjacent fixation, and veterinary trauma procedures where a 3.5mm locking screw matches the implant plan. The surgeon selects the correct length after measuring the prepared track and confirming near cortex, far cortex, plate thickness, trajectory, and target purchase. Proper use depends on compatible drill guides, hex drivers, locking plates, reduction forceps, bone quality, and the selected veterinary implant system.
The 10mm, 12mm, 14mm, 16mm, 18mm, and 20mm variants are selected for shallower fixation points, compact bone corridors, and plate positions where limited working length is required. The 22mm, 24mm, 26mm, 28mm, 30mm, 32mm, 34mm, 36mm, 38mm, and 40mm options support routine locking plate fixation when moderate cortical purchase is confirmed by depth measurement. The 45mm, 50mm, 55mm, 60mm, 65mm, and 70mm variants are selected for deeper trajectories, larger patient anatomy, longer plate constructs, or fixation points requiring extended working length. Each hole should be measured after drilling so the selected screw matches the actual bone corridor and plate position. Keeping the full range in inventory allows the surgical team to respond to intraoperative depth measurements without changing screw diameter or locking head style. Variant selection follows drilled depth, plate thickness, screw angle, cortical thickness, and construct role.
Stainless steel construction supports thread integrity, head geometry, shaft strength, and handling during orthopedic tray preparation. Before surgical use, the team should inspect the locking head, hex recess, self-tapping tip, threads, and shaft for visible damage, contamination, deformation, or packaging concerns. The hex recess should remain clean and clearly defined so the driver seats fully during insertion. The locking head must engage the compatible plate hole without cross-threading, incomplete seating, or driver slip. Implant handling should follow facility protocol for sterile transfer, documentation, tray organization, and single-patient orthopedic use. Procurement teams can standardize Self-Tapping Locking Screw 3.5mm variants with compatible TPLO plates, locking plates, drill guides, depth gauges, hex screwdrivers, screw racks, and implant storage systems. CE marking, ISO 13485 certification, and FDA compliance support purchasing documentation for veterinary hospitals, distributors, teaching programs, and institutional buyers maintaining repeat orthopedic case inventory.

How does Self-Tapping Locking Screw 3.5mm compare with a standard cortex screw?
Self-Tapping Locking Screw 3.5mm is designed to lock into a compatible plate hole, creating a fixed-angle screw-plate construct. A standard cortex screw seats against a conventional plate hole and relies more directly on plate-to-bone compression. The locking screw is selected when the orthopedic plan requires angular stability through a locking plate system. The self-tapping tip supports insertion after pilot drilling when the chosen protocol allows direct advancement. A standard cortex screw may be selected for conventional compression or neutralization plating. The choice follows plate design, bone quality, fracture pattern, TPLO construct requirements, and surgeon technique.
Which length should be selected from the 10mm to 70mm range?
Length selection follows drilling, depth measurement, plate thickness, bone corridor, screw trajectory, and intended purchase. Shorter 10mm to 20mm options support shallower fixation points and compact plate positions. Mid-range 22mm to 40mm screws cover many routine TPLO and locking plate applications. Longer 45mm to 70mm options are selected for deeper measured tracks, larger patients, and longer orthopedic constructs. The surgeon confirms each hole with a depth gauge before choosing the final length. Accurate selection supports proper seating and reduces unwanted protrusion beyond the target cortex.
How do CE, ISO 13485, and FDA compliance support procurement?
Self-Tapping Locking Screw 3.5mm supports procurement programs that require documented sourcing for veterinary orthopedic implants. CE marking supports international conformity records for regulated purchasing environments. ISO 13485 certification supports manufacturing control, inspection consistency, traceability, and quality-system documentation. FDA compliance language supports USA-facing procurement files where supplier and device records are reviewed. These credentials help veterinary hospitals, referral centers, distributors, and teaching programs standardize TPLO and locking plate implant inventories. The one-piece MOQ, OEM availability, warranty coverage, and return and replacement support assist repeat purchasing and distributor planning.
How is the self-tapping locking head used during insertion?
The surgeon prepares the pilot hole using the compatible drill guide and measures the required depth. The selected screw is loaded onto the matching hex driver with the head aligned to the locking plate hole. As insertion begins, the self-tapping tip advances through the prepared track while the shaft threads engage cortical bone. The locking head then seats into the plate interface to create the intended screw-plate relationship. The driver remains aligned to avoid cross-threading or incomplete engagement. Final seating is confirmed by tactile feedback, plate stability, and construct inspection before closure.
What role does this screw serve in a veterinary orthopedic implant inventory?
Self-Tapping Locking Screw 3.5mm serves as a core screw option for TPLO plates, locking plate constructs, fracture stabilization, corrective osteotomy, and trauma fixation trays. It is stored with compatible locking plates, drill guides, drill bits, depth gauges, hex drivers, reduction forceps, screw racks, and implant handling supplies. The 10mm to 70mm range helps the surgical team match screw length to each measured plate hole. Keeping the full range available reduces intraoperative compromise caused by missing lengths. The screw family supports standardized case preparation for veterinary orthopedic clinics, referral hospitals, and distributor inventories.
