We stock a wide variety of fasteners ideal for many applications around the home, farm, business, automotive, and in industry. Most of our fasteners have a light zinc plating over steel giving a more rust resistant finish. We also sell coated and stainless products for additional rust resistance. We stock many grades of fasteners ranging from low carbon steel on up to hardened, heat treated steel. Not all fasteners are applicable for all applications so be certain to test thoroughly and get the opinion of a licensed builder or certified building or structural engineer before relying on these fasteners for any situations where failure would result in damage to property or person.

  • Premium Strength: Manufactured from Grade 8 hardened steel for superior durability and high-torque applications
  • Course Threaded: Designed with a course thread for a more secure attachment between pieces. Compatible with standard nuts and washers.
  • Hex Cap Construction: These large bolts feature a hex cap that allows for greater torque application than circular caps
  • Large Hex Bolts: The greater diameter of these steel hex bolts allows for stronger, more heavy-duty load bearing across the join
  • Versatile Use: Ideal for automotive, industrial, and heavy machinery projects requiring maximum fastening security. The corrosion-resistant zinc finish protects against corrosion for long-lasting performance indoors and outdoors.
  • Diameter: 3/8"
  • Length: 1-1/4 inch
