5/8" ASTM A193 B8 / A194 Gr 8 Stainless Steel Heavy Hex Hardware Lot

​Up for sale is a clean lot of industrial-grade 5/8" 304 stainless steel heavy hex hardware. This is high-strength, corrosion-resistant, high-temperature rated fastening hardware—far superior to standard commercial or off-the-shelf stainless.

​Included in Lot:

​(48) 5/8"-11 x 4" Heavy Hex Bolts (Head Stamped: B8)

​(96) 5/8"-11 Heavy Hex Nuts (Face Stamped: 8)

​Specifications & Details:

​Bolt Spec: ASTM A193 Grade B8 (High-pressure / high-temperature 304 Stainless)

​Nut Spec: ASTM A194 Grade 8 Heavy Hex

​Pattern: Heavy Hex — Requires a 1-1/16" wrench/socket (wider head and thicker nut body than standard 15/16" 5/8" hardware for higher load/torque capacity).

​Condition: Fully cleaned, spotless, clean threads, ready to install.

​Paperwork / Certification Note:

Sold WITHOUT Mill Test Reports (MTRs) or trace papers. Because there are no certs, these cannot be used for certified code-inspected pressure piping or vessel installations.

​However, for heavy equipment repairs, structural steel fabrication, custom machinery, skid builds, or high-end shop inventory where you want maximum strength and rust resistance without paying $1,300+ at an industrial supplier, this is a top-tier lot.

​Price: $500 CAD for the entire lot (Cash or E-transfer).

Location: Meet up in the Camrose / Wetaskiwin area.
