The Moroso 5/16-18 serrated zinc flange bolts are sold as a 10-pack for general fastening and light fabrication needs. Each flange bolt uses a serrated seating surface to resist loosening under vibration and zinc plating to slow corrosion. The common 5/16-18 thread makes these fasteners useful for service, small engine fixtures, and aftermarket assemblies where flange-style bolts are preferred.
