Astm A307a ((link))

This is where Grade A shines. It is the mechanically rated bolt you can buy. It is stocked at every hardware store, big-box retailer, and industrial supplier in the country. No special ordering. No long lead times.

ASTM A307 is the standard specification for carbon steel bolts, studs, and threaded rods with tensile strengths ranging from 60,000 to 100,000 psi. It is broken down into three distinct grades: astm a307a

ASTM A307 is the standard specification for carbon steel bolts, studs, and threaded rods with a tensile strength of 60,000 psi. It is the most common standard for general-purpose fasteners. This is where Grade A shines

If you are ordering threaded rod for general hanging or anchoring, you are almost always looking for ASTM A307A . No special ordering

Head markings are the easiest way to identify your fastener. While markings can vary by manufacturer, A307A bolts typically display the manufacturer's symbol and may not have radial lines like high-strength bolts. Always verify the Mill Test Report (MTR) to confirm compliance.

According to the standard, a standard hex nut is the proper companion. These nuts are also low-carbon and will deform before the bolt fails, ensuring ductile behavior.
