Lesson 1 • Manual Torque Wrench Types and Use

Covers click, beam, dial, and electronic torque wrenches with correct operating technique. Ensures students apply torque accurately and avoid common user errors.

Lesson 2 • Pneumatic Impact and Pulse Tools

Explains impact wrench and pulse tool operating principles and their torque output variability. Students learn when these tools are appropriate and how to control output.

Lesson 3 • Tool Selection for Application

Provides a decision framework matching tool type to torque range, access, and accuracy needs. Students justify tool selection in a given assembly scenario.

Lesson 1 • Tightening Strategy Programming

Teaches multi-stage tightening strategies including torque-to-torque, torque-to-angle, and yield-point control. Students configure strategies to maximize preload accuracy.

Lesson 2 • DC Electric Nutrunner Fundamentals

Covers motor types, transducer feedback, and controller architecture in DC electric tools. Provides the technical basis for programming and troubleshooting these systems.

Lesson 3 • System Integration and Error Proofing

Addresses tool network integration, barcode scanning, and poka-yoke features that prevent assembly errors. Students design an error-proofing scheme for a sample assembly.

Lesson 4 • Maintenance and Troubleshooting

Covers preventive maintenance schedules, common fault codes, and systematic troubleshooting for electric tightening systems. Students resolve simulated tool faults.

Lesson 1 • Lubrication Application

Covers lubricant types, application methods, and coverage requirements for consistent nut factor. Students apply lubricant correctly and verify coverage before tightening.

Lesson 2 • Thread Engagement and Hole Preparation

Addresses minimum thread engagement, hole cleaning, and tapped hole inspection. Ensures the threaded interface can sustain the required clamp load without stripping.

Lesson 3 • Mating Surface Preparation

Details cleaning, flatness verification, and surface finish requirements for bolted interfaces. Connects surface condition to friction coefficient and preload accuracy.

Lesson 1 • Multi-Pass Tightening Techniques

Explains star pattern, percentage-of-final, and sequential multi-pass methods for uniform clamp load. Students apply each method and measure resulting load distribution.

Lesson 2 • Structural Bolting Procedures

Covers snug-tight, pretensioned, and slip-critical installation methods for structural connections. Students apply the correct method based on connection classification.

Lesson 3 • Flange and Gasketed Joint Assembly

Applies multi-pass tightening to pressure-containing flanged joints with gasket compression requirements. Students follow a flange assembly procedure to achieve leak-free sealing.

Lesson 4 • Work Instruction Development

Guides students in writing clear, complete assembly work instructions from engineering inputs. Produces a usable document that controls the assembly process on the shop floor.

Lesson 1 • Torque Audit Methods

Teaches residual torque, breakaway torque, and torque-angle audit techniques with acceptance criteria. Students perform each audit type and classify results correctly.

Lesson 2 • Visual and Dimensional Inspection

Covers marking, thread protrusion, and alignment checks performed after tightening. Provides a systematic inspection checklist students apply to completed assemblies.

Lesson 3 • Nonconformance and Corrective Action

Establishes the process for documenting, containing, and resolving bolted joint nonconformances. Students complete a root cause analysis and corrective action for a sample defect.

Lesson 4 • Statistical Process Control for Tightening

Applies control charts and capability indices to tightening process data. Students calculate Cpk and interpret control charts to assess process stability.
