Specify the head and joint for the sheet-metal fastener request. The photograph shows elongated transverse-head bolts and hex nuts rather than a confirmed square flat head.
Set the head contact within the sheet joint
Define head width, bearing face, anti-rotation requirement, shank dimensions and thread engagement. Choose one metric or inch standard with actual diameter and pitch.
- Select the transverse or requested square head profile.
- Define bearing, shank and thread dimensions.
- Specify actual material and property-class standard.
- Confirm the mating nut and passivated surface scope.
- Agree joint-specific dimensional and mechanical checks.
Separate A2-70 from stainless chemistry
SS304 or SS316 names do not establish the carbon-steel strength classes in the general menu. A2-70 needs applicable fastener evidence for the selected material and configuration.
Verify acceptance for fabrication duty
Provide sheet thickness, tightening requirements, quantities and revision. Fit, load capacity and corrosion performance require relevant records for the supplied joint rather than a photograph or general grade list.
Our Custom A2-70 Stainless Steel 304 Square Flat Head Bolts are designed for exceptional performance and durability in sheet metal fabrication. These bolts offer a precision-manufactured square flat head, making them ideal for a variety of industrial and commercial applications where tight fastening and corrosion resistance are essential.
