Cleaning, Locking & Assembly

Drawing review example

Decide when to clean, apply locking patches and assemble seals

Illustrative drawing review. Confirm the route, dimensions and acceptance for your part.

What drives the route: For a captive screw with a seal or pre-applied patch, map every later cleaning, coating or heating step against compatibility. Identify the sealing face, required retention and patch position. Keep the passage and the useful thread clear of unintended residue.
What changes the quotation: Price the sequence as delivered: cleaning and drying, patch application or washer/seal assembly, sorting and packaging. Define cleanliness and any torque or reuse requirement by method and conditions rather than ordering a generic clean or locked part.
How to release the sample: Verify final condition after all operations and protective packing. Check retention, seal orientation and patch coverage separately from the agreed functional trial. Record the lot and distinguish technical-cleanliness results from any inspection of visible debris.

Process decision and release matrix

Resolve these items during technical review. Each row identifies a decision or evidence requirement; it does not imply a universal process limit or an in-house equipment claim.

Decision	Required input	Release question
Burr and residue	Identify internal/external edges, passages and contamination concerns	What edge condition and cleaning acceptance does the application need?
Locking feature	Specify patch/adhesive type, coverage and assembled requirements	What installation, reuse or torque behavior is to be verified?
Pre-assembly	Show washers, seals or springs and their retention	What sequence avoids exposing components to incompatible later processing?
Packaging	Agree lot separation, protection and labeling	How will the approved parts reach assembly in the required condition?

AFTER PROCESSING

See the resulting feature.

Visual references help explain geometry and finish. Material properties, coating performance and acceptance require the agreed inspection methods.

Post-processing — clean and deburred — Process outcome reference; final requirements follow the approved drawing.

Inputs and outputs for Cleaning, Locking & Assembly

The process review begins with Hollow & Through-Hole Screws, Captive Screws, Custom Flange Screws, Modified-Tip Self-Tapping Screws and the actual drawing, not a generic equipment list. Identify the incoming stock or part condition and the dimensions that must remain controlled at this stage.

Use the process topics above to resolve cleaning and burr control; technical cleanliness; pre-applied locking systems; pre-assembly and sorting. Record the selected requirements in the order specification. A process name does not establish the resulting tolerance, property class or inspection coverage.

Coordinate the next operation

The next review may involve CCD Vision & Dimensional Inspection or Coatings & Surface Treatments. Check which surfaces are used to locate the part, whether the next operation changes dimensions and at what stage final acceptance is measured. Where a requirement cannot be checked after assembly or finishing, agree an intermediate check as well as final verification.

For samples involving tooling, the typical lead time is approximately 10–15 days, subject to drawing review and confirmation of material, finishing and inspection scope. The complete route determines the confirmed schedule; the duration is not a promise for each individual process.
