In wrench sets, they will be all positioned in order from smallest size to largest. SAE and metric nuts and bolts will need to be used with the corresponding wrench sizes. For example, an SAE nut will need to be used with an SAE wrench to ensure that you get the correct fit. Similarly, a metric bolt should be used with a metric-sized wrench.

Measurement system: INCH, Metric Size: 1/4''-4''; M6 - M100 Grade / Class: ASTM A194 2, 2H, 4, 7, 7M,8, 8M; A563 Gr. A, C, Thread: M, UNC, UNF Heavy Hex Nut Dimensions Description Heavy hex nuts are slightly larger and thicker than standard (finished) hex nuts. There are numerous grades and the heavy pattern is typically used for

To determine if a nut is metric or standard, look for a dash (-) followed by a number in the size designation. For example, M12-1.75 is a metric nut and 3/8-16 is a standard nut. What does SAE bolts stand for? The Society of Automotive Engineers (SAE) designation for bolts is a standard system for determining the strength of bolts.

Metric Bolt Conversion. Metric bolt conversion data for industrial bolts/rods , machine screws and small diameter fasteners from Raaj Sagar Steels includes metric to standard bolt conversions. The chart below shows metric bolt conversions and DIN numbers for fasteners.

Metric 18-8 Stainless Steel Thin Hex Nuts. Useful in low-clearance applications, these metric nuts are roughly half the height of standard hex nuts, but aren't as strong. All are 18-8 stainless steel, which is nearly as strong as steel but won't rust in outdoor, washdown, and other corrosive environments.
