Define the assembly condition
Complete the Details Your Assembly Needs
Assembly-ready sheet metal parts start with clear thread, hardware and connection details, consistent across drawing, BOM and assembly references.
Fastener Models and Quantities
Provide the manufacturer, full part number and quantity for each installed fastener. Include specified material and finish requirements.
BOM and Assembly References
Match hardware items to the BOM and assembly drawing. Show installation locations, orientation and the current document revisions.
Hardware Supply Arrangements
State whether hardware will be customer-supplied or sourced for the project. Confirm purchasing responsibilities and approval requirements for alternatives.
Hole and thread definition
Tapping and Drilling Requirements
Tapping and drilling for sheet metal parts should be reviewed around thread engagement, hole accuracy and access after forming.
Specify the Complete Thread
For sheet metal tapping, provide the thread standard, size, pitch and tolerance class where required. Identify through or blind threads and the usable thread depth.
Define Finished Hole Requirements
For sheet metal drilling, specify finished hole diameter, positional requirements and inspection datums. Identify any holes that require drilling or reaming after initial cutting.
Review Thickness and Tool Access
Check available thread engagement against sheet thickness and connection requirements. Nearby bends, short flanges and restricted access may affect the operation or fastening choice.
Protect Threads Through Finishing
Identify threads and mating surfaces that require protection during coating or finishing. Confirm inspection requirements for the final delivery condition.
Installed hardware
Fastener Insertion and Riveting Options
Review self-clinching fastener installation and sheet metal riveting against the sheet material, thickness and connection geometry.
Self-Clinching Nuts
Add internal threads to sheet metal mounting points. Review the selected nut, sheet thickness, hardness and installation-hole requirements together.
Self-Clinching Studs
Provide fixed external threads for mounting components. Specify thread size, projection length, installation side and clearance.
Standoffs and Spacers
Create spacing between panels or mounted components. Confirm length, thread details, orientation and mating-part clearance.
Riveted Connections
Join sheet metal components using the specified rivet. Review total grip thickness, hole preparation and installation access.
Specified PEM Fasteners: For PEM fastener insertion, give the full part number and location. Installation follows the product's sheet and hole specifications.
Review Your Fastener and Connection Requirements
Share your drawing and hardware list to discuss installation compatibility and assembly access.
Four-step review
Thread, Fastener and Assembly Inspection
Check assembly features against the approved drawing, BOM and agreed inspection requirements.
Verify Documents and Hardware
Confirm drawing revisions, thread specifications and fastener models.
Check Threads and Holes
Inspect specified thread and hole features against the agreed criteria.
Verify Fastener Installation
Check fastener quantity, orientation and seating against the drawing.
Review Assembly Fit
Check critical clearances and mating positions using the provided references.
Retention testing: Specify any push-out, torque-out or retention tests at quotation; methods and acceptance criteria are agreed before production.

Frequently asked questions
Sheet Metal Secondary Operations FAQ
What sheet metal secondary operations can STARWAY review?
STARWAY reviews sheet metal tapping, drilling, self-clinching fastener installation and riveting for custom parts. Share your drawings and assembly requirements so we can assess the operations, access and manufacturing sequence needed for the next assembly stage.
What information is needed for tapping and drilling for sheet metal parts?
Specify thread standards, sizes, pitches and usable thread depths, together with finished hole dimensions and inspection datums. Identify through or blind features and critical mating locations. Nearby bends, sheet thickness and tool access should also be considered during review.
Can thin sheet metal be tapped directly?
Suitability depends on material, thickness, required thread engagement and connection requirements. Direct tapping may not provide enough engagement for every application. Self-clinching nuts or other fastening options can be reviewed where additional thread engagement is needed.
How do I specify PEM fastener installation for sheet metal?
Provide the complete PEM part number, quantity and installation location. Include sheet material, thickness, insertion side and required projection. Installation holes, edge distances and sheet-hardness limits must follow the selected product's specifications. Any alternative fastener requires approval.
What details are needed for sheet metal riveting?
Provide the rivet type, material, diameter and specified grip range, together with the combined thickness of the joined parts. Show hole locations, installation direction and available access. Include any load, sealing or cosmetic requirements for joint review.
Should fasteners be installed before or after coating?
The sequence depends on the fastener specifications, coating process and final assembly requirements. Review thread protection, coating buildup, installation marks and fastener seating before confirming the route. Mark cosmetic areas and mating surfaces that require protection.
How are threads and installed fasteners inspected?
Inspection follows the agreed drawing and BOM requirements. Checks can cover thread features, hole dimensions, hardware identity, quantity, seating and orientation. Mating references help verify assembly fit. Special retention testing requires agreed methods and acceptance criteria before production.
What should I send for an assembly-ready sheet metal parts quote?
Send part drawings, material and thickness, quantity, thread specifications and the fastener list. Include the BOM, assembly drawing and current revisions where applicable. State the hardware supply arrangement, finishing and inspection requirements, and target delivery date. Each uploaded file must be smaller than 130 MB.
