Define the actual bolt head and sheet-metal joint required. The examples show elongated transverse heads and hexagonal nuts rather than verified square flat heads.
Locate the under-head contact within the joint
Dimension head width, bearing face, anti-rotation clearance, shank length and thread engagement. Select the metric or inch standard, diameter and pitch for the mating nut.
- Select the head and joint drawing.
- Define bearing and anti-rotation geometry.
- Specify actual material and property-class requirements.
- Confirm nut inclusion and compatible passivation.
- Agree dimensional and relevant mechanical evidence.
Specify SS304 independently of A2-70
A2-70 is not a simple synonym for SS304. SS316 and the carbon or high-strength-steel class references are separate options, not simultaneous properties of one bolt.
Verify the delivered sheet-metal fastener
Provide sheet thickness, tightening conditions, quantities and drawing revision. Structural load, corrosion duration and secure fit require applicable fastener and joint records rather than a general material menu.

Our Custom Stainless Steel 304 Square Flat Head Bolts A2-70 are designed specifically for sheet metal fabrication, providing exceptional strength and corrosion resistance for industrial applications. Manufactured with precision, these bolts ensure reliable fastening and long-lasting performance even in demanding environments.

The bolts are available in various head styles, including hexagon, T head, eye, flange, and round options, catering to diverse engineering needs. Each bolt features a metric system thread and is made from high-quality stainless steel A2-70, equivalent to SS304 grade, for superior durability and passivation-treated surface for enhanced rust protection.

Choose from a range of mechanical classes such as 4.8, 5.6, 6.8, 8.8, 10.9, SS304, and SS316, as well as different materials like carbon steel and high-strength steel to meet your project's specifications. Bulk packaging is secure, with 20-25 kg per cardboard box and up to 900 kg per pallet, ensuring safe transportation for wholesale orders.

These square flat head bolts are ideal for OEM manufacturers, construction companies, and machinery suppliers who require custom solutions at competitive Chinese wholesale prices. Trust our factory's expertise and customization capabilities to deliver the right fasteners for your business.
