Our heavy black hex bolts are made from grade 8, featuring an overall length of 7 and a diameter of 9/16. Their zinc plated finish ensures corrosion resistance while the grade 8 material offers excellent tensile strength and high resistance to wear, making them suitable for industrial applications that require durable bolts. These hex bolts are compatible with 1 5/32 or larger hardware nuts or coupler nuts for a tight and secure hold, ideal for assemblies where strong bolt retention is necessary. Their overall length of 7 provides enough thread engagement for securing materials while the standard hex head design provides access to tight spots making them useful in automotive, structural, or equipment fabrication where high strength bolts are required.
