Specify the actual bolt head for the sheet-metal joint. The examples show hex-head bolts and separate nuts, not verified square flat heads or a flush installation.
Define the bearing contact and mating thread
Provide head geometry, shank length, thread standard, diameter, pitch and nut engagement. Include sheet thickness and required tightening conditions on the selected drawing.
Select material independently from property class
SS304 or SS316 needs an actual material specification. A2-70 and the general carbon-steel class references are different requirements, not interchangeable ratings or certification of the pictured bolts.
- Select the head and sheet-joint drawing.
- Dimension bearing face and threaded engagement.
- Specify actual alloy and applicable property class.
- Confirm nut scope and compatible passivation.
- Agree relevant dimensional and mechanical records.
Verify the delivered fastener's identity and duty
YISHENG and YS001 are source identifiers rather than verified Relia identity or authorization. Fit, load and corrosion performance require applicable evidence for the actual ordered joint.
The YISHENG YS001 A2-70 Custom Stainless Steel 304 Square Flat Head Bolt is engineered to meet the demanding requirements of sheet metal applications. Manufactured from premium-grade SS304 stainless steel, this bolt delivers exceptional corrosion resistance and strength, making it ideal for both indoor and outdoor usage in industrial environments.
