There are several different thread series available for construction fasteners. Below are the three of the most common thread series utilized in the fastener industry. Unified National Coarse UNC — Coarse threads have fewer threads per axial distance than fine threads and a larger thread form relative to the diameter. Coarse thread bolts are often used in the construction industry because they allow for more rapid assembly, are more resistant to damage from handling or corrosion, and lend themselves to thicker corrosion resistant coatings. Coarse threads also provide greater resistance to internal thread stripping and, because if this, are often used with relatively low strength material.

ASTM A is a fastener specification covering alloy and stainless steel bolts and threaded studs for use with flanges, valves, pressure vessels, and fittings for high temperature and high pressure service. Various grades exist within the A specification and vary in chemical composition, mechanical properties, and high temperature characteristics. The most common grade within the A specification is Grade B7, however several other grades exist. Fasteners under the A specification are most commonly specified, manufactured, and supplied as heavy hex bolts or fully threaded studs. However, the specification does not restrict A fasteners to only these items. A variety of bent bolts, rods with thread on one or both ends, and headed bolts other than heavy hex are commonly provided under the A specification. All bolts and studs shall be chamfered pointed. ASTM A is a related specification that covers a group of common requirements as they relate to the A specification. Section 13 of the A specification addresses thread form and class. Certain grades of fasteners manufactured to ASTM A can be zinc coated per F hot-dip galvanized , B mechanically galvanized , or F zinc plated. Allowance for the omission of product marking on very small diameter fasteners and makings in alternate locations are laid out in section 17 of the A specification, but rarely come into play. Dual grade markings are allowed provided the fasteners meet all requirements of both specifications.

Bolts with hexagonal heads and machine threads for use with a nut or in a tapped hole. Also known as hex cap screws or machine bolts. Flange bolts have a flange on the bottom of the head that distributes the load like a washer. Screws with machine threads for use with a nut or in a tapped hole. Bolts with no drive and machine threads for use with a nut. Screws with no head and machine threads for use in a tapped hole. Nuts have internal machine threads, for use with machine thread bolts and screws. Used to spread the load of a bolt or screw over a larger area or to help prevent loosening under vibration. A fully threaded rod with no head or drive. Commonly used in manufacturing, automotive, electrical, plumbing, and general construction applications.

Grade B7, these threaded rods have a tensile strength about one and a half times stronger than low-strength steel rods. They meet the pressure and temperature requirements of ASTM A and are often used to secure pressure tanks, valves, and flanges. Made of Grade B7 steel, the tensile strength of these threaded rods is one and a half times higher than low-strength steel threaded rods.
