Define the metal-fabrication bolt by its required head and connection dimensions before selecting material or mating hardware.
Separate the requested head from the photograph
This metal-fabrication enquiry requests square or flat heads, while the example shows hex-head bolts with blue packaging or sleeves. Neither the head alternative nor SS304 chemistry can be verified from that image.
Locate the bolt in the fabricated joint
Specify clearance, seating contact and access for installation. YS001 is a source model reference, not a fastener standard or verified property designation.
Define the selected bolt configuration
- Draw the square or flat head and its bearing face.
- State sheet stack and required thread engagement.
- Name the metric or inch thread standard.
- Identify SS304 material and any property requirement.
