What is ASME B18.2.2?
ASME B18.2.2 is an American national standard that was developed by the American Society of Mechanical Engineers (ASME) under its B18 Committee on Fasteners. It was first published in 1948 and has been revised several times since then, with the latest edition being issued in 2020.
The scope and purpose of the standard
The standard covers nuts for general applications, such as machine screw nuts, hex nuts, square nuts, hex flange nuts, and coupling nuts in inch series. It does not cover special-purpose nuts, such as locknuts, slotted nuts, castle nuts, wing nuts, etc., which are covered by other standards.
The purpose of the standard is to provide uniformity and consistency in the design, manufacture, testing, inspection, and marking of nuts that are intended for use with bolts, screws, studs, and other fasteners that conform to ASME B18 standards or other recognized standards.
The main types and dimensions of nuts covered by the standard
The standard defines five main types of nuts based on their shape and function:
Machine screw nuts: These are small hexagonal or square nuts that are used with machine screws or similar small-diameter fasteners.
Hex nuts: These are six-sided nuts that are used with bolts or studs that have a hexagonal head or shank.
Square nuts: These are four-sided nuts that are used with bolts or studs that have a square head or shank.
Hex flange nuts: These are hexagonal nuts that have a flange or washer at one end that provides a larger bearing surface and prevents the nut from loosening.
Coupling nuts: These are long hexagonal or cylindrical nuts that are used to join two threaded rods or studs end-to-end.
The standard specifies the nominal sizes, threads, widths across flats, widths across corners, thicknesses, and chamfers for each type of nut. It also provides tables of dimensions and tolerances for each size and grade of nut. The standard covers nut sizes from #0 to 6 in. and grades from 2 to 8, with different grades indicating different mechanical properties and hardness levels.
Why do you need ASME B18.2.2?
If you are involved in the design, engineering, fabrication, installation, maintenance, or repair of mechanical systems or structures that use nuts as fasteners, you need ASME B18.2.2 for several reasons:
The benefits and applications of using nuts that conform to the standard
Using nuts that conform to ASME B18.2.2 can offer you the following benefits:
Quality and reliability: You can be assured that the nuts you use meet the minimum requirements for strength, durability, corrosion resistance, and performance under various conditions.
Safety and compliance: You can avoid potential hazards and liabilities that may arise from using substandard or defective nuts that may fail or cause damage to the system or structure.
Compatibility and interchangeability: You can easily find and use nuts that match the size, thread, and grade of the bolts, screws, studs, or other fasteners that you are using.
Cost-effectiveness and efficiency: You can save time and money by reducing the need for testing, inspection, sorting, or rework of nuts that may not fit or function properly.
Using nuts that conform to ASME B18.2.2 can also enable you to comply with various codes, regulations, specifications, or contracts that may require or recommend the use of this standard for certain applications. Some examples of such applications are:
Building and construction: Nuts are used to fasten structural elements, such as beams, columns, trusses, frames, etc., as well as non-structural elements, such as doors, windows, cabinets, etc.
Machinery and equipment: Nuts are used to fasten components, such as gears, shafts, bearings, motors, pumps, valves, etc., as well as accessories, such as guards, covers, handles, etc.
Automotive and transportation: Nuts are used to fasten parts, such as wheels, axles, brakes, suspension, steering, engine, transmission, etc., as well as accessories, such as lights, mirrors, seats, etc.
Aerospace and defense: Nuts are used to fasten parts, such as wings, fuselage, landing gear, engine, propeller, etc., as well as accessories, such as instruments, controls, sensors, etc.
In these applications, nuts have to withstand high stresses, vibrations, temperatures, pressures, and corrosive environments. Therefore, nuts that conform to ASME B18.2.2 can provide high performance and reliability for aerospace and defense applications.
