What size nut is M20?
20mm
M20 (20mm) Thread Size. 16mm Nut Thickness (T)
Can you use a regular nut as a jam nut?
The term “jam nut” can also refer to any nut that is used in the same function (even a standard nut used for the jamming purpose). Jam nuts, other types of locknuts, lock washers, and thread-locking fluid are ways to prevent vibration from loosening a bolted joint.
How thick is a jam nut?
Jam nut size refers to its nominal thread diameter. Typically, sizes range from 1/4″ to about 2 1/2″.
What is a half jam nut?
Hex Lock Nuts, also called Jam Nuts are thin nuts that lock another hexagon nut in place by clamping without exerting force, when tightened. The Hex Lock Nuts can also be used when a standard Hex Nut would not fit.
What grade are jam nuts?
Jam Nuts are often used to lock or “jam” something in place without clamping against another object; Jam Nuts are typically low profile compared to a standard nut. Grade A per ASTM A563 hardness: HRB 68 Minimum.
What size nut goes on a 1/4 bolt?
US Nut Size Table
| Size | Diameter* | Height |
|---|---|---|
| Hex Nut | Hex Nut | |
| 1/4″ | 7/16″ | 7/32″ |
| 5/16″ | 1/2″ | 17/64″ |
| 3/8″ | 9/16″ | 21/64″ |
Why are jam nuts thinner?
Jam nuts are thinner because it helps save space when locking a pair of nuts together.

Why are Hex jam nuts good for low clearance?
Made with fine-pitch threads, vibration is less likely to loosen these metric nuts than those with coarse-pitch threads since the threads sit closer together. Also called jam nuts, they are roughly half the height of standard hex nuts, so they’re good for applications with low clearance.
What’s the best way to tighten a metric nut?
Tighten these nuts by turning them to the left; once fastened, they resist loosening from counterclockwise motion. These metric nuts have good chemical resistance and may be mildly magnetic. These metric nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.
What kind of stainless steel are metric nuts made of?
These metric nuts are made of 316 stainless steel and half as tall as regular hex nuts— use them around chemicals and salt water when space is limited. Made of 316 stainless steel for excellent corrosion resistance— including in salt water— these nuts tighten to the left and won’t loosen from counterclockwise motion.
What kind of nuts can I use in a small space?
Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels. These nuts are half the height of standard hex nuts, and have closely spaced threads to prevent loosening from vibration.
