The example shows broad round-head fasteners, a separate hex-head bolt and a washer. A square or flat head request needs its own drawing; the photograph does not verify SS304 chemistry.
Select the head and bearing contact
Dimension the required profile and installation clearance against the sheet-metal joint. Distinguish head shape from the shank grip and thread engagement.
State the actual fastener requirements
Choose thread series, diameter and pitch, plus matching nut and washer requirements. Stainless grade and numeric steel property classes describe different selections.
- Draw the selected square or flat head.
- Locate smooth grip through the sheet stack.
- Specify thread start and engagement length.
- Identify material and property requirements.
- Agree hardware finish and joint checks.
Confirm evidence for the ordered configuration
Review passivation against the selected material and service conditions. YISHENG source wording does not independently verify Relia authorization; quantities and acceptance documents require order agreement.
