ANSI Zinc Plated Round Head Square Neck Bolt M20 BSW Thread - Carbon Steel Grade 4.8-8.8 Industrial Fastener

These M20 BSW thread bolts are ideal for applications requiring minimal surface projection and moderate load capacity.
- Square neck prevents rotation during installation and use
- Round head design minimizes protruding surface height
- Blue-white zinc plating provides corrosion resistance
