Jam nuts are smaller than average nuts, roughly half the size. In actual use, these nuts are well-tightened against one another after being screwed onto the bolt. You might utilize jam nuts for several different purposes. The first situation is if you are fastening to exceptionally soft material and you cannot take the chance of damaging the material by doing so. The second situation is when you need to secure something to the bolt while still allowing it to move. Explore our selection of Brown JAM NUT SET 3/4-10 (3/4-10 JN SET), which are ideal for commercial fastening operations where a regular nut won't fit. Utilize them with fasteners to tightly lock in machinery. Threading these nuts over the bolts will prevent loosening. Use these when a conventional nut doesn't fit because of the lack of room. Different nut designs are available in stainless steel and carbon steel. Our jam nuts have a hexagonal body and a circular opening.
