1/4"-20 Zinc Plated Steel Coarse Thread Hex Bolts
These high-quality fasteners are engineered for reliability and durability in a wide range of general-purpose fastening applications. Manufactured from robust steel and finished with a protective zinc plating, these bolts offer essential corrosion resistance for indoor environments and standard construction projects.
This collection features both hex cap screws and carriage bolts to meet various mechanical and structural needs. The hex cap screws are designed with a hexagonal head for a secure fit and ease of installation using a standard 7/16" wrench. The carriage bolts feature a domed head with a square section underneath the head that grips into the material—typically wood—preventing the bolt from turning when the nut is tightened.
The coarse threading on all variants ensures a strong grip in various materials, making them a versatile choice for maintenance, repair tasks, and industrial assembly. These fasteners meet standard specifications for Grade 2 / A307 steel, ensuring consistent performance and quality for your hardware needs.
