Error-Proof Your Line Before Defects Ship
See how vision AI error-proofs assembly steps before defects leave the station.
Add a real-time verification layer to every fastened joint with vision AI for fastener verification. Built for the lines where a torqued bolt and a snug bolt look identical from a step away, two bolt grades differ by a head mark a few millimeters wide, and the missing fastener announces itself months later and miles away. Whether you're running assembly stations, torque cells, or final checks, Roboflow verifies every bolt, nut, washer, and rivet at line rate, with per-unit records tied to serial and VIN behind every assembly.

What is fastener verification with Vision AI?
Fastener verification with vision AI uses computer vision models to verify fastened joints through assembly: presence and count of bolts, nuts, screws, and rivets against each variant's expected map, washer and clip presence, grade mark and head type checks, seating and flushness, and torque stripe and witness mark verification. Models trained on your actual assemblies verify every joint at line rate, with per-unit records tied to serial and VIN that support IATF 16949 and AS9100 documentation.
Can Vision AI tell nearly identical fasteners apart?
Fasteners are the near-twin problem: an M8 and an M10 a step apart on the same bracket, grade marks that differ by a numeral a few millimeters wide, black-oxide and phosphate finishes that read the same under station light, and a hundred of them per assembly. Deep-learning models trained on your actual fasteners, joints, and lighting learn the differences that matter for each position, verify each joint against the variant's expected map, hold that judgment across model mix, and route uncertain joints to a check instead of guessing, which is how the wrong bolt gets caught at the station instead of the audit.
Does this replace torque monitoring?
No. DC nutrunners and torque controllers keep owning clamp load, angle, and the torque trace; those curves remain the joint's functional record. Vision AI adds what the tool can't see: the joint the tool never reached, the washer missing under a properly torqued head, the wrong-grade bolt that torqued fine, the proud head sitting at an angle, and the stripe that never got struck. Torque traces and visual verification land in the same per-unit record, joint by joint.
Can it integrate with our torque tools, PLCs, and MES?
Yes. Roboflow Inference exposes a standard API and supports common industrial protocols, so fastener verification events flow into your existing systems: station and torque cell PLCs from Allen-Bradley and Siemens, MES and ERP platforms like SAP and Oracle, and SCADA and HMI platforms like Ignition and AVEVA, through REST, MQTT, OPC UA, and direct database writes. PLC-level integration holds an assembly the moment a joint fails verification, and every event carries unit serial, station, joint, imagery, and disposition, with a full audit trail behind every build.
