Plain Finish A307 Hex Bolts – Versatile, Jobsite-Ready Fasteners for General Construction

A307 hex bolts with a plain (uncoated) finish are a staple in general construction, utility work, and machinery assembly. Manufactured from low-carbon steel and conforming to ASTM A307 standards, these bolts are commonly used for non-critical structural connections where corrosion resistance isn’t a primary concern. They're ideal for use in dry, interior environments or where finish coatings like zinc or galvanization are not required.

Whether you're bolting together wood framing, securing steel plates, or assembling utility infrastructure, A307 hex bolts offer dependable strength and value. The plain finish makes them easy to weld, modify, or coat as needed in fabrication shops or field installs.

  • ASTM A307 Rated: Meets standards for general-purpose carbon steel bolts
  • Plain Finish: Uncoated for welding, fabrication, or protected interior use
  • Hex Head Design: Easy to install with standard tools for a wide range of construction applications

Available in multiple diameters and lengths to match your job specs. Most orders placed before 4:00pm CST ship out the same day, Fasteners Plus has you covered.
