M12 x 30 Purlin Flange Bolt & Nut Kit - Grade 8.8 High Tensile Zinc

Features and Benefits

• Grade 8.8 tensile strength provides substantially higher clamping force capacity than Grade 4.6.
• Integral serrated flange replaces a separate washer while improving anti-loosening performance.
• Zinc plated for corrosion protection within roofing and cladding environments.
• M12 and M16 coverage for the standard range of high-load purlin connections.

Typical Applications

• High-load purlin and girt connections in heavy industrial or commercial steel buildings.
• Structural connections where Grade 4.6 is insufficient and Grade 8.8 is specified.
• Roof and wall cladding systems in buildings with high wind or seismic design loads.
• Portal frame and steel building connections requiring high-tensile flange bolts.
