Key Features

Thread Accuracy:Threaded features inspected using go/no-go gauges.
Controlled Dimensions: Critical dimensions identified on engineering drawings receive specific inspection attention.

Surface Finish:Specified surface roughness of Ra 1.6 μm for turned surfaces and Ra 3.2 μm for milled surfaces, where applicable.

Clean Finish:Burr-free edges, controlled chamfers and no visible scratches or indentations.

Engineering Considerations

Thread Fit · Dimensional Tolerances · Surface Quality

Thread specifications, critical dimensions and mating interfaces are defined by engineering drawings. Unless otherwise specified, general dimensional tolerances follow ISO 2768-m, and unspecified chamfers are C0.1 mm.

Manufacturing Process

01 — Drawing & Specification Review

Confirm material grade, thread specifications, critical dimensions and applicable tolerances.

02 — CNC Turning & Milling

Machine bolt heads, shanks, profiles and other specified features according to the approved drawings.

03 — Thread Machining

Machine the bracket profile, mounting bosses and bores, followed by finishing passes on critical features.

04 — Deburring & Chamfering

Remove sharp edges and burrs, applying C0.1 mm chamfers where specified by the drawing requirements.

05 — Surface Finishing

Meet specified surface roughness requirements for turned and milled surfaces.

06 — Dimensional & Visual Inspection

Inspect critical dimensions, thread conformity, surface finish and visible defects.

07 — Kit Verification & Packaging

Verify kit quantities and component specifications before protective packaging and shipment.

Quality Inspection

Thread Inspection:Check all threaded features using appropriate go/no-go gauges.

Dimensional Inspection:Inspect critical dimensions identified on the drawing and apply ISO 2768-m general tolerances where applicable.

Surface Roughness:Verify specified roughness requirements: Ra 1.6 μm for turned surfaces and Ra 3.2 μm for milled surfaces, where applicable.

Visual Inspection:Check for scratches, indentations, burrs and sharp edges.

Kit Completeness:Verify component types and quantities against the approved packing list.
