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.

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. Unified coarse threads are specified on the majority of common ASTM construction fastener grades. Unified National Fine UNF — Fine threads have more threads per axial distance than coarse threads and a smaller thread form relative to the diameter. Fine thread bolts are often used in OEM type applications such as automotive, machinery, etc. Fine threads are also frequently used with high strength bolts because they have less thread depth and a greater minor diameter in comparison to bolts with coarse threads. UNF threads will be stronger and more resistant to vibration loosening than UNC threads, but are susceptible to damage and cross threading. However, the 8-thread series is also used where and engineer is looking for a compromise between coarse and fine thread series. As the thread class increases the tolerances become tighter more precise. The A and B following the class designate whether the threads are external A or internal B. Class 1 threads are loose tolerance threads meant to allow for quick and easy assembly even if the threads are slightly damaged.

However, in recent years the metric thread standard is becoming more common. The standard defines diameter and pitch combinations along with allowances , tolerances, and designations. The basic dimensions are nominal dimensions of a unified thread profile without allowance and tolerances The thread class defines that. The basic dimensions can be used for design. However, for manufacturing and machining, you need the allowable range of each dimension.

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.
