Fastener Verification AI Across Assembly, Torque, and Final Check

Deploy Anywhere, Run Everywhere
Run fastener verification on the edge, on-prem, in your VPC, or via API, wherever your assembly stations, torque cells, and final check lines need it.
One Platform, Full Adoption
Tools every assembly team can adopt, from station operators and torque techs to line leads, manufacturing engineers, and quality managers, no separate ML team required to ship and own inspection models.
Secure, Compliant, and Audit-Ready
Data stays safe with SOC 2 Type II compliance, encrypted data, and an uptime SLA, with per-unit records that support IATF 16949, AS9100, and customer-specific PPAP audit requirements.

Talk to a vision AI engineer who's shipped fastener verification.

A subframe bolt that never made it in, a lower-grade bolt that torqued fine and stretched under load, or a joint that got snugged but never struck can mean a warranty campaign counted in torque audits, a joint that held at the plant and let go on the road, and a recall traced to one station on one shift. Bring us your toughest fastener verification problem and we'll map a working solution.

Ask us about:

Solution architecture for IATF 16949, AS9100, and customer-specific PPAP environments
Live demo on your joint imagery, station photos, or torque cell footage
Deployment options: edge, on-prem, air-gapped, or VPC, with integration into torque tools, station PLCs, and MES

Verify Every Bolt on Every Joint, with Vision AI

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.

Presence, Count, and Position:

Verify every fastener is present and counted on every joint, against the expected map for each variant
Confirm washers, clips, and retainers are present under heads and in position, not just the bolts above them
Catch missing and extra fasteners before a panel, cover, or carpet closes over the evidence

Correct Part and Condition:

Check grade marks, head types, lengths, and finishes, so the 8.8 that reached a 10.9 joint gets caught at the station
Flag proud, cross-threaded, and unseated fasteners, the heads that sit at an angle no torque trace reports
Detect damaged heads, stripped drives, and thread damage before the tool makes them worse

Torque Marks, Lines, and Systems Integration:

Verify torque stripes and witness marks are present and aligned on every marked joint, on every unit
Trend findings by station, tool, and shift, so a drifting process shows up before an audit finds it
Route assemblies in real time through PLC and MES integration, with per-unit records tied to serial and VIN that support IATF 16949 and AS9100 documentation

Bring intelligence to every joint today. Stop fastener defects from becoming torque audit findings, roadside failures, or the recall traced to one station on one shift.

More About Fastener Verification

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.
